Which groups on the periodic table form covalent bonds?
groups 3-12 (the Transition Metals)
group 18 (the Noble gases)
groups 1 & 2 (Alkali Metals and Alkaline Earth Metals)
groups 14-17
Why do you think that the nonmetals in group 18, the Noble Gases, don't form covalent bonds? Click all that apply.
They satisfy the octet rule and already have 8 electrons in the outermost electron shell
They actually do form covalent bonds.
Noble Gases satisfy the Octet Rule
Noble gases aren't really nonmetals.
Atoms can share electrons equally or unequally. When Atoms share electrons unequally, they are known as
non-polar covalent bonds
polar covalent bonds
