What is Oxidation in Chemistry? (athleticinsight.com)

These subatomic particles are removed from the substrate during oxidation. (athleticinsight.com)

Specifically, glucose, the chief energy source for cells, undergoes oxidation to produce adenosine triphosphate (ATP), the primary energy currency within biological systems. (athleticinsight.com)

It is seen that electron affinities generally increase on crossing the periods (same trend as for IE's, and for the same reason). (nyxnews.com)

This property of elements changes as we move towards the right side of the table, where the elements tend to gain electrons and have a negative oxidation number. (scienceabc.com)

Finally, oxidation is key to the combustion of hydrocarbons, a process that powers engines and generates electricity. (athleticinsight.com)
