Respuesta :

Answer:

they gain the few electrons they need to form full octets

They gain the few electrons they need to form full octets. Hence, option C is correct.

What are electrons?

Electrons are the smallest of the particles that make up an atom, and they carry a negative charge

The outer shells of non-metal atoms gain electrons when they form ions: the ions formed are negative because they have more electrons than protons. the ions formed have full outer shells.

Hence, option C is correct.
