The first analysis on a rock started on Sol 3 with Barnacle Bill. The Alpha Particle X-ray Spectrometer (APXS) was used to determine its composition, the spectrometer taking ten hours to make a full scan of the sample. It found all the elements except hydrogen, which constitutes just 0.1 percent of the rocks or soils mass.. The APXS works by irradiating rocks and soil samples with alpha particles (helium nuclei, which consist of two protons and two neutrons). The results indicated that "Barnacle Bill" is much like Earths andesites, confirming past volcanic activity. The discovery of andesites shows that some Martian rocks have been remelted and reprocessed. On Earth, Andesite forms when magma sits in pockets of rock while some of the iron and magnesium settle out. Consequently, the final rock contains less iron and magnesiums and more silica. Volcanic rocks are usually classified by comparing the relative amount of alkalis (Na2O and K2O) with the amount of silica (SiO2). Andesite is different ...
Two days ago, Curiosity stopped to analyze a football-size piece of Martian basalt called Jake Matijevic. Not only did Curiosity analyze the rocks structure and chemical makeup using itsChemCam spectroscopic laser, but it also used its Alpha Particle X-Ray Spectrometer (APXS) for the first time, and also took the first ultra-close-up photos using the MAHLI camera. The rock was primarily chosen to see if the results from APXS match up with ChemCam.. ...

This ingenious illustrated periodic table by Keith Enevoldsen shows how the chemical elements are part of daily life and is available in a printed version.
The history of the periodic table reflects over a century of growth in the understanding of chemical properties, and culminates with the publication of the first actual periodic table by Dmitri Mendeleev in 1869. [1] While Mendeleev built upon earlier discoveries by such scientists as Antoine-Laurent de Lavoisier and Stanislao Cannizzaro, the Russian scientist is generally given sole credit for development of the actualperiodic table itself. The table itself is a visual representation of the periodic law which states that certain properties of elements repeat periodically when arranged by atomic number.. The table arranges elements into vertical columns (groups) and horizontal rows (periods) to display these commonalities. ----------------- Elemental ideas from ancient times People have known about some chemical elements like gold, silver and copper from antiquity, as these can all be discovered in nature in native form and are relatively simple to mine with primitive tools. [2] However, the ...

The collection of atmospheric deposition by technical samplers and validated deposition modelling using chemical transport models is spatially complemented by using mosses as bioindicator: since 1990, the European moss survey has been providing data on element concentrations in moss every 5 years at up to 7300 sampling sites. In the moss specimens, heavy metals (since 1990), nitrogen (since 2005) and persistent organic pollutants (since 2010) were determined. Germany participated in all surveys with the exception of that in 2010. In this study, the spatial structures of element concentrations in moss collected in Germany between 1990 and 2015 were comparatively investigated by using Morans I statistics and Variogram analysis and mapped by use of Kriging interpolation. This is the precondition to spatially join the moss survey data with data collected at other locations within different environmental networks and to validate spatial patterns of atmospheric deposition as derived by technical sampling and
Occult Chemistry: Investigations by Clairvoyant Magnification into the Structure of the Atoms of the Periodic Table and Some Compounds is a book written by Annie Besant, C.W. Leadbeater and Curuppumullage Jinarajadasa, who were all members of the Theosophical Society (based at Adyar, India). Annie was at the time the President of the Society having succeeded Henry Olcott after his death in 1907. The first edition was published in 1908, the second edition in 1919, and a third in 1951. Since the first edition was published in 1908, the book is in the public domain, and available in whole or in excerpts, on many sites on the internet. Occult Chemistry states that the structure of chemical elements can be assessed through clairvoyant observation with the microscopic vision of the third eye. Observations were carried out between 1895 and 1933. "The book consists both of coordinated and illustrated descriptions of presumed etheric counterparts of the atoms of the then known chemical elements, and of ...
The nuclei of hydrogen and most helium atoms were formed about one microsecond and three minutes respectively after the original Big Bang. Heavier elements were made later, by nuclear reactions in the core of stars - the heaviest reactions being formed inside exploding stars.. It is estimated that the rate of element formation peaked sharply at around 11,000 million years ago. Galaxies around 6000 million light years distant (redshift z=0.5) show more blue, element making stars than nearer (closer to us in time) galaxies do.. The average age of those elements heavier than hydrogen, found in meteorites and on earth, is, according to ...

There might be not a single person around who dont know the harmful effects of smoking. But unfortunately, people tend to overlook the probable health damage they may experience through this bad habit. However, this article is another attempt to elaborate the injurious elements that cigarettes and tobacco smokes contain and make those realize the necessity of quitting immediately.. Nicotine: Nicotine is a strong insecticide and the most poisonous element for nervous system. If 50mg of nicotine which is equivalent to four cigarettes is injected directly into a mans bloodstream, he will die in just few minuets. Indeed, many casualties have occurred with children when they swallowed cigarettes or their butts.. Nicotine reaches the brain when diluted in smoke in just seven seconds and kindles the brain cells followed by blocking the nervous impulse. This is the place where tobacco addiction arises. Nicotine is also responsible for accelerated heart beats and all at once it contracts and hardens ...

Emphasizing, the other potential applications of biotechnology, the new NASA/Berkeley study mentions replenishing gases for life support only briefly. As well discuss a little later in connection with rocket fuel, the chemical elements needed, oxygen and nitrogen, are available in and in the vicinity of the places where we might put outposts. Its just that the atoms of these elements are not in a breathable form. Rather theyre combined with atoms of other chemical elements. On Mars, for instance, theres plenty of oxygen, but not a drop is useful either to mix with propellant in rocket engines, or for humans to breath. Thats because Martian oxygen atoms are bound with carbon atoms in molecules of carbon dioxide (CO2). For humans, CO2 is a waste product; instead, we need to breathe molecular oxygen (O2) to support life functions. But, in the presence of light, photosynthetic organisms, such as plants, algae, and certain bacteria take in CO2 and water (H2O) in and release O2. In the process, ...

Standard atomic weights last revised based on the 2005 review published in Pure Appl. Chem. 78(11), 2051-2066, 2006 and Aug 2007 release, and here reported to 5 significant figures. Elements with no reported values in the table above have no stable nuclides (alternative tables might display mean relative atomic masses or mass numbers for an arbitrarily selected unstable nuclide of that chemical element). However, three such elements -Th, Pa, and U- have a characteristic terresterial isotopic composition, and for these an atomic weight is tabulated..

Greetings, and welcome to the third installment of a regular feature on the Radleys blog - the Element of the Month.. To choose our element of the month, we used a random number generator to produce a figure between 1 and 118 - the current number of elements in the periodic table. This month, we drew the number 83, which makes bismuth our third element of the month.. Bismuth - The Key Facts. Bismuth is a chemical element with symbol Bi and atomic number 83. It is one of the few elements whose liquid state has a higher density than its solid state.. Almost twice as abundant as gold in the earths crust, bismuth is a brittle metal, silvery white in colour when it is freshly produced, and often seen with a pink tinge due to surface oxidation once in contact with air. Bismuth crystals are truly stunning, as the varying layers of oxidation disturb the light wavelengths that reflect on its surface, creating a veritable rainbow of colours.. Although rather alien-looking, you may be surprised to know ...
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a blue-silvery appearance when oxidation is removed. It is the first element in group 12 of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size. Zinc is the 24th most abundant element in Earths crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity (electrowinning).more.

Within the last six-eight years many papers have reported an association between increased levels of particulate (aerodynamic size less than 10 microns in diameter) air pollution and increased daily death rates and illness in major cities in the US, Europe, and South America. There is a need to better characterize the emission rates and chemical composition of particles emitted from vehicles equipped with the latest emission reduction technology. Particle-mass emission rates were measured for four 1995 Ford vehicles driven over three different driving cycles: the Urban Dynamometer Driving Schedule (UDDS), the Highway Fuel Economy Test (HFET), and the USO6 driving cycle. The average particle-mass emission rates were less than 10 mg/mi for any of the driving cycles. The particle-mass emission rate was least for the HFET and about equal for the UDDS and the USO6 cycles. The elemental composition of the particles, determined by X-ray fluorescence, suggests that 10-30% of the particle-mass is ...
