Front

Define ionic bond.

Back

A type of chemical bond that involves the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What is the significance of the octet rule in chemical bonding?

Back

It explains how atoms tend to bond in order to achieve a full outer shell of electrons, typically 8.

Front

What is a metallic bond?

Back

A bond formed by the attraction between positively charged metal ions and the electrons in a metal.
