What will be the valency of the element whose atom has three protons and four neutrons?

Open in App

Solution

Valency will be 1.
Given the element has 3 protons means it has 3 electrons as well.
Mass number =3+4=7
Thus the electronic configuration will be: 2,1
It has only one electron in the valence shell and by losing this electron it can attain stability.
Hence its valency will be one.
