Select the true statments
Metals are poor conductors of electricity because they hold their electrons tightly.
Polymers with a lot of cross-linking are usually rigid.
Ionic compounds tend to be brittle.
Metals tend to be brittle.
A substance with hydrogen bonding usually has higher viscosity than a similar molecule without hydrogen bonding.
A nonpolar substance with weak dispersion forces tends to have high surface tension.
