Q

What is ionic bonding?

A

The electrostatic attraction between oppositely charged ions.

17
Q

Why are almost all ionic compounds solids at room temperature?

A

Not enough energy to overcome strong electrostatic attraction between oppositely charged ions in giant ionic lattice.

18
Q

What about ions affects solubility?

A

The size of charge
Higher charge = more difficult for water to break down = less soluble

19
Q

What is covalent bonding?

A

The strong electrostatic attraction between a shared pair of electrons

20
Q

What is dative/co-ordinate covalent bond?

A

Where one atom donates a lone pair of electrons to another atom/ion
