Question

why
The lithium forms +1 ions &
berylium forms +2 ions.​

Answer 1

Answer:

because of stability

Explanation:

as lithium has one electron in its outermost shell after releasing it it becomes Li+1 ion

and beryllium has 2 electron in it's outer shell

Answer 2

Answer: That's because lithium is in group I and beryllium in group II

Explanation: When the electrons are filled in the electron shells in lithium it's 2,1 it forms a +1 charge because it needs to loose one electron inorder to gain stable elctronic configuration.

In beryllium electons are filled 2,2 so it needs to loose two electrons to gain stable electronic configuraon so it form +2 charge .

Losing electrons means it forms + charge .
