What kind of bond holds together molecules?

COVALENT

200

The presence of a central unshared pair or uneven electronegativity of elements would result in this type of molecule.

POLAR

300

A compound with a very high electronegativity difference would be formed of this kind of bond.

IONIC

400

An electron dot configuration is called this.

LEWIS STRUCTURE

500

A model in chemistry used to predict the shape of individual molecules based upon valence shell electron pair repulsion.
