A

reactions that release energy

17
Q

What is always exothermic?

A

The formation of ionic compounds from positive ions and negative ions.

18
Q

Lattice energy

A

energy required to seperate 1 mol of ions of an ionic compound

19
Q

The greater the lattice energy…

A

…the stronger the force of attraction

20
Q

(+ or o) Lattice energy is related to ion size.

A

+

21
Q

As the distance between opposite charges decrease…

A

the electrostatic force of attraction between opposite charges increase

22
Q

Smaller ions form compounds with more closely spaced ionic charges…

A

…so they have stronger attractions and greater lattice energy.
