Answer:
Oxidation means the loss of electrons in metal atoms. The oxidation of a metal occurs when the metal loses one or more electrons, so that the atoms of the metal go from the neutral state and become a positively charge ion. This commonly results in the formation of a metal oxide (in the case of iron, that is known as rust).
It occurs in the presence of oxygen. For example,
Metals can also be oxidized when they are dissolved, for instance dissolving zinc metal in a solution of acid leads to Zn2+ ions in solution and the formation of hydrogen gas.
See the Related links for more information about oxidation process.
It occurs in the presence of oxygen. For example,
- Iron> (water +oxygen)= iron oxide
- mercury>(heat above 350 °C + oxygen)= Mercury oxide
- sodium>(water, even slight vapor in air+ oxygen) = sodium oxide.
