Question

Sodium (Atomic.No.11) readily forms ions whereas neon (Atomic.No.10 )does not . Explain why?​

Answer 1

Explanation:

Sodium ( Na)

Electronic configuration : 2 , 8 , 1

Neon (Ne)

Electronic configuration: 2 ,8

Since sodium has 1 electron in its outermost shell it transfers the electron to gain stability and hence form ion whereas neon has filled outermost shell and is already stable

Answer 2

Answer:

outermost shell of a  neutral sodium atom consists 1 electron so it loses it (forming Na+)  to make its second shell the outermost which consists 8 electrons and completes the octate whereas, a neutral neon atom have 8 electrons in its outermost shell and its octate is already complete so it doesnot need to form ion.
