For example:
If we add a small amount of arsenic to silicon, several valence electrons of each arsenic atom will form covalent bonds with the neighbouring atoms of silicon.
If gallium is introduced into a silicon crystal, each gallium atom will attempt to form a covalent bond with each of its four neighbouring silicon atoms.
