Front

What kind of chemical bond forms between a metal and a nonmetal?

Back

Ionic bond: A type of bond formed when electrons are transferred from one atom to another.

Front

What is electronegativity?

Back

Electronegativity: A measure of an atom's ability to attract and hold onto electrons.

Front

What is a nonpolar covalent bond?

Back

Nonpolar covalent bond: A bond where electrons are shared equally between two nonmetals.

Front

What is an ionic bond?

Back

Ionic bond: A bond formed through the transfer of electrons from a metal to a nonmetal.

Front

What is a metallic bond?

Back

Metallic bond: A bond formed by the attraction between positively charged metal ions and the electrons around them.

Front

What is a polar molecule?

Back

Polar molecule: A molecule with a partial positive charge on one side and a partial negative charge on the other due to unequal sharing of electrons.
