Question

stability order Li,Li^+1,Li^+2

Answer 1

the atomic no of Li,Li^+1,Li^+2 are 3,2,1 respectively.
so the right order is Li^+1 > Li > Li^+2.

Answer 2

Hey there!!!

We can find the order of stability by the electronic configuration.

☆ In Li(3) , the electronic configuration would be: 1s^2 2p^1

☆ In Li^+1(2) , the electronic configuration would be: 1s^2 2p^0

☆ In Li^+2 (1) , the electronic configuration would be: 1s^1 2p^0.

We know that only half filled or fully filled orbitals are more stable.

So, the order of stability would be :

Li^+1 > Li > Li^+2.
