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,
- Iron> (water +oxygen)= iron oxide
- Mercury>(heat above 350 °C + oxygen)= Mercury oxide
- sodium>(water, even slight vapor in air+ oxygen) = sodium oxide.
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.

When elemental Lithium metal reacts with Elemental Bromine what is oxidized and what is reduced?
The lithium is oxidized an the bromine is reduced. In a chemical reaction involving a metal in elemental form, the metal will be oxidized.
What oxidized metal caused substantial quantities of oxygen to accumulate in Earth's atmosphere?
iron
An oxide ion is oxidized to an oxygen atom by what?
An oxygen atom can only be oxidized by some element with an equal or higher electronegativity. So, oxygen can be oxidized by fluorine (e.g., OF2) or by another oxygen atom (e.g., O2).
What are the color of metals?
Most metals are grey, as ores, unless oxidized. Then they become brown or red. Only gold and copper are not.variesmetallic colour, sort of shiny, metal-ish.
IFA metal forms two oxides the higher oxide contain 80 Metal 0.72Gm of lower oxide gave 0.8Gm of the higher oxide when oxidized show these data illustrate law of multiplication?
(100 -0.72)% = 99.2 (100 - 0.8)%=99.2
When elemental Lithium metal reacts with Elemental Bromine what is oxidized and what is reduced?
The lithium is oxidized an the bromine is reduced. In a chemical reaction involving a metal in elemental form, the metal will be oxidized.
What reaction will a metal have if it has no reaction with air?
This metal is not oxidized.
Is oxidized metal organic compound?
No. Only compounds containing carbon are organic. "Oxidized metal" is merely a metal with a coating of a corresponding metal compound, usually an oxide.
When 1 gram of metal is oxidized what is the resulting mass?
What metal?
Which is easily oxidized metal aluminium or lead?
Aluminium is more easily oxidized than lead.
Which metal Zn or Cu can be oxidized easily?
Zinc is oxidized more easily than copper.
Which metal was oxidized by two other ions?
Zinc
Why freshly cut metal has lustrous surface?
A freshly cut metal is not oxidized or contaminated.
What type of reaction happens when a metal gain oxygens?
It is an oxidation/reduction reaction. The metal loses electrons to become positively charged (it is oxidized) and the oxygen gains those electrons to become negatively charged (it is reduced). You end up with a metal oxide.
What metal is oxidized in the most common dry cell?
Zinc
