Question

Name four ions that have this electronic confrigation 1s1 2s2 2p6

Answer 1

Answer:

Not possible.

Explanation:

It is not possible to have an electronic configuration with 2nd shell fulfilled and the 1st shell half filled.

If however the configuration is 1s2 2s2 2p6, Then four ions having the required configuration are... Ne, F(-1),O(-2),Na(+1),Mg(+2). The integer in bracket denote the charge on the elements.

Answer 2

Answer:

Explanation:

neon (Ne), argon (Ar), and krypton (Kr), Helium (He)
