Question

Write an equation that shows the formation of a lithium ion from a neutral lithium atom

Answer 1

Li + e- ===> Li+
it looses its valence electron to form a uni-positive ion

Answer 2

Answer: The equation for this is given below.

Explanation:

Lithium is the 3rd element of the periodic table having electronic configuration of $1s^22s^1$

This element will loose 1 electron to attain stable electronic configuration.

Oxidation reaction is defined as the reaction in which an atom looses its electron to form a positive ion.

The chemical equation for the formation of lithium ion from lithium atom follows:

$Li\rightarrow Li^++e^-$

Hence, lithium ion will form lithium cation by loosing 1 electron as shown in above equation.
