Question

Formation of a positive ion from an atom is oxidation.
If true enter 1, else enter 0.

• A. 1
• B. 0
• C. Both
• D. None

Answer 1

The correct option is A 1

Formation of a positive ion from an atom is oxidation. This involves loss of electrons by an atom or an ion or a molecule and the oxidation number increases. For example, sodium metal is oxidized to sodium ion by losing one electron. The oxidation number of sodium increases from $0$ to $+1$.
Oxidation: $Na\to N{a}^{+}+e^{-}$
