Answer: The ion formed by lithium element is $Li^+$

Explanation:

Ions are formed when an atom looses or gains electrons.

If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form $F^-$ ions.

If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form $Na^+$ ions.

Lithium is the 3rd element of the periodic table having 3 electrons.

The electronic configuration of lithium element = $1s^22s^1$

This element will loose 1 electron to attain stable electronic configuration and will lead to the formation of $Li^+$ ion.

Hence, the ion formed by lithium element is $Li^+$
