What is the most stable monatomic ion formed from lithium?
s344n2d4d5 [400]

<u>Answer:</u> The ion formed by lithium element is Li^+

<u>Explanation:</u>

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^+
