Will lithium gain one electron when it reacts to form a compound?

No, lithium loses one electron to form a compound. It is an alkali metal with an electron configuration of 1s² 2s¹, so it tends to lose one electron to achieve a stable electron configuration.


What is the complete electron configuration of lithium?

The complete electron configuration of lithium is 1s^2 2s^1. This means that lithium has 3 electrons, with 2 electrons in the 1s orbital and 1 electron in the 2s orbital.

Why lithium highly reactive?

if lithium loses one electron it attains the stable noble gas electron configuration of helium. hence it is highly reactive.


When reacting with an atom of chlorine an atom of lithium will lose an electron and become a litium?

In a reaction with chlorine, a lithium atom will lose an electron to achieve a stable electron configuration. Once it loses an electron, it becomes a lithium cation, which has a charge of +1.
