Question

what side of the periodic table tends to gain electrons to form ions?

Answer 1

The non-metallic elements on the right-hand side of the periodic table tend to gain electrons to form ions. These elements are located in groups 15, 16, and 17 (also known as the nitrogen group, oxygen group, and halogens group, respectively). The elements in these groups typically have higher electron affinities and higher electronegativities, which means they have a stronger tendency to gain electrons to achieve a stable electron configuration.
