Question

If the electronic configuration of Ca (Calcium) is 1s?, 25², 2p", 3s?; 3pº,4s’and Ne (Neon) is 152,2s2 2p6. Which element is more stable and why? Ca or Ne?​

Answer 1

Answer:

Neon is more stable than Calcium. This is because Calcium has an incomplete electronic configuration and has 2 electrons in its outermost shell. Whereas, Neon has 8 electrons in its outermost shell making it a complete, stable element. And the reason behind this is we know that having 8 electrons in outermost shell makes an element stable [Octet Rule].

I hope this helps.
