Match it! Select the correct answer from the pull down...Good luck!

How many electrons are involved in a double bond?

Lattice energy increases as ionic charges * and as their radii *.

Ionic compounds have * melting points and covalent compounds have relative * melting ponts.

Bond breaking is always * and bond forming is always *.

Arrange NaF, CsI and CaO in order of decreasing lattice energy.

List the following in order of decreasing bond polarity: C-F, Be-F, O-F

Bond length * as the number of shared electron pairs increases.

The electronegativity of an atom generally decreases to the * and *.
