Bookmark Glossary Terms Humans have always used materials from the earth selectively. Early human artists who painted on rock walls made their own paints from red and yellow pigments present in soils pigments we now know as the minerals hematite and ochre. Countries have fought wars and trade companies battled over deposits of table salt also called halite in the East Indies.

2020-8-3 · Oxidation may be a spontaneous process or it may be started artificially. Sometimes it is helpful and sometimes it is very destructive. At its most basic level oxidation is the loss of electrons
Oxygen constitutes about 21 per cent of atmospheric gases and is very reactive. All elements on earth react with oxygen to form oxygen-containing compounds. Of the oxygen compounds binary compounds of oxygen with lesser electronegative elements are called oxides. Fluorine is the only element having large electronegativity than oxygen.
