Chemical Bonds

What elements generally make an ionic bond ?

• Metal and nonmetal

• 2 or more nonmetals

• 2 or more metals

• 2 elements

An ionic bond is formed when

• Valence electrons are shared.

• Valence electrons surround the cations.

• Valence electrons are transferred between atoms.

• Valence electrons are completely transferred between two metals.

What is a valence electron?

• an electron that is found in the outermost shell of an atom

• an electron found in the innermost shell of an atom

• an electron found in the middle shell

• an electon found in the nucleus
