Ionic bonding

Question 1

Ionic bonding takes place between what type of elements?

Answer 1

Between metals and non-metals

Question 2

Why do atoms react to form ionic bonds?

Answer 2

To achieve and electron configuration of a noble gas.

Question 3

What charge do the metal and non-metal ions make?

Answer 3

Electrons transferred from metals to non-metals. Metal: lose electrons( +)
Non-metals: gain electrons( - )

Question 4

What forces of attraction holds a giant ionic lattice?

Answer 4

Strongs electrostatic forces of attraction between oppositely charged ions.

Question 5

List (and explain where necessary) 4 properties of ionic compounds

Answer 5

1. High MP/BP
2. Do not conduct electricity unless dissolved or molten (ions can move and carry charge when molten otherwise they are in fixed positions).
3. Brittle (if ions of the same charge meet, they will repel and structure will break).
4. Soluble in polar solvents, eg. water
