  • Isotopes
  • Its unstability is explained by Mattauch's rule which states that if two elements with consecutive atomic numbers each have an isotope of the same weight, one of the isotopes will be unstable and radioactive. (simply.science)
  • Kinetics
  • theories of reaction rates - collision and transition state theory, relaxation kinetics, kinetics of photochemical reactions and free radical polymerization, homogeneous catalysis, adsorption isotherms and heterogeneous catalysis. (way2freshers.com)
  • conductors
  • The most striking similarities shared by the 24 elements in question are that they are all metals and that most of them are hard, strong, and lustrous, have high melting and boiling points, and are good conductors of heat and electricity. (britannica.com)
  • brittle
  • When materials like rubbers and elastomers need to retain flexibility, they should be used and stored above the glass transition temperature (otherwise, it runs the risk of becoming brittle). (element.com)
  • stability
  • 27 technical papers were presented on prediction of crystal structure and phase stability, characterization of interfaces and grain boundaries at atomic scale, optimization of electrical, optical and mechanical properties, modeling of defects and related properties, design of materials and components at different length scales, application of novel computational methods for processing.
