Dihydrogen Monoxide

Front

Define covalent bond.

Back

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

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What are intermolecular forces?

Back

Intermolecular forces are forces of attraction or repulsion which act between neighboring particles (molecules, atoms, or ions).

Front

What is a polar molecule?

Back

A polar molecule has a net dipole moment due to the presence of polar bonds that do not cancel out.

Front
