Covalent Bonding Basics

What is a covalent bond?

• a bond where neutrons are shared

• a bond where one electron is lost forever

• a bond where two atoms share a pair of electrons

• a bond where two atoms lose 3 protons

What group of elements on the periodic table typically form COVALENT bonds?

• Metals

• Metalloids

• Nonmetals

Which groups on the periodic table form covalent bonds?

What is the octet rule?

• Atoms want to have 2 electrons in the valence (outer) electron shell in order to be stable.

• Atoms want to have 8 electrons in the valence (outer) electron shell in order to be stable.

• Atoms want to lose all their electrons

• Atoms want to gain as many electrons as possible.

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 aren't really nonmetals.
