Explanation:
The electrons in the outermost shell of an atom are the valence electrons. These electrons are the most loosely held in an atom.
The energy required to remove these electrons are not as great as those of the inner shell electrons.
- Atoms of some elements show no tendency to combine with other atoms because they have completely filled outer energy levels.
- Their outermost shell, valence shell and the electron numbers are complete for them. These are the noble gases.
- other atoms share or exchange their valence electrons in order to have a stable configuration.
- The valence electrons are involve in inter-atomic bond formation and interactions
- Also the distribution of these electrons determines inter-molecular interactions between molecules.

The substance doesn't have a specific name. We just say that that substance is being reduced. Remember this mnemonic - OILRIG where "Oxidation is Loss, Reduction is Gain" of electrons.
