Front

Why are covalent compounds non-conductive to electricity?

Back

They do NOT contain charged atoms (ions).

Front

What is the basis of a metallic bond?

Back

The attraction between positive metal ions and free floating electrons.

Front

Define solubility.

Back

The ability of a substance to dissolve in a solvent, forming a solution.

Front

What is hydrogen bonding?

Back

A strong type of dipole-dipole attraction between molecules that occurs when hydrogen is bonded to highly electronegative atoms like N, O, or F.

Front

What are covalent compounds?

Back

Compounds formed by the sharing of electrons between nonmetal 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 metallic bonds?

Back

Bonds formed by the attraction between positively charged metal ions and the electrons that are delocalized among them.
