Atoms form ions in order to make a (a) outer shell.
Ionic bonds are formed between which type of atoms?
Metals only
A metal and a non-metal
Non-metals only
Two or more of the same atoms
How is an ionic bond formed?
Shared pair of electrons between 2 atoms.
Transfer of electrons from one atom to another.
A sea of delocalised electrons.
When 2 or more neutral atoms are near to each other.
What is an ionic bond?
The electrostatic attraction between oppositely charges ions.
The electrostatic attraction between a shared pair of electrons and the positively charged nuclei of the atoms involved.
The electrostatic attraction between positive metal ions surrounded by a sea of delocalised electrons.
Select all that apply to ionic substances...
They have low melting points due to weak intermolecular forces.
They have very high melting points.
It takes a lot of energy to overcome the strong electrostatic attractions between oppositely charged ions.

Why does NaCl have a high melting point?
It takes a lot of energy to overcome the strong electrostatic attraction of the ionic bond.
NaCl has lots of weak ionic bonds, and therefore it doesn't take much energy to melt it.
Because NaCl dissolves easily in water.
Because it doesn't take a lot of energy to break the intermolecular forces.
Select the properties that apply to ionic substances.
High melting points.
Conduct electricity when molten.
Conduct electricity when solid.
Strong electrostatic attractions between oppositely charged ions.
Strong electrostatic attractions between neutral atoms in the compound.
