Question

write the electronic configuration of alkaly metals and alkaline earth metals​

Answer 1

Hey buddy! Here's yo' answer:

Alkali metals have one electron in their valence shell.

The electronic configuration is given by ns1. For example, the electronic configuration of lithium is given by 1ns1 2ns1.

They tend to lose the outer shell electron to form cations with charge +1 (monovalent ions).

This makes them the most electropositive elements and due to the same reason, they are not found in the pure state.

Hope you are safe and doing well, love.  :)
