Question

An element of group 15 has atomic number 15. Examine if this element will have metallic properties or not. Also give name of the element.​

Answer 1

Answer:

The element is phosphorous.

The electronic configuration of phosphorous is:

$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{3}$

Since the p-orbital of the valence shell is half filled , therefore it has a stable configuration.

This concludes that it would be difficult for removal of electron from the valence shell. Therefore phosphorous will not show metallic properties.
