The salts from weakest to strongest lattice energy in the order is 1432.

1. calcium oxide 4. aluminum chloride 3. calcium chloride 2. sodium chloride

The energy required to split a mole of an electrovalent solid into gaseous ions is referred to as lattice energy. The two main factors contributing to lattice energy are:

the charge of the ions i.e. as charge rises, lattice energy increasesthe size of the ions i.e. as the size rises, lattice energy decreases.

The lattice energy helps to measure the bond strength in electrovalent compounds.

The reaction between group 1 element (alkali metal) and group 7 element (halogen family) is known as electrovalent bond and the greater the electrovalent bonding the stronger the lattice energy.

From the given compounds, In terms of lattice energy;

Sodium chloride will be greater than calcium chloride because the size of sodium is smaller compared to that of calcium. Also, the bond strength in Sodium chloride is greater than that of calcium chloride.

Also, the charge on Alumiumn is 3+ and that of Calcium is 2+. Hence, the lattice energy of aluminium chloride is higher than that of calcium oxide.

Therefore, in order of increasing lattice energy from the weakest to the strongest lattice energy, the order is 1432.

Answer from: hardwick744

1324

Explanation:

Lattice energy is defined as the energy required to released when ions are combined to make a compound. Lattice energy depends on the charge on the ions, and the size of the ion, small is the size strong is the lattice energy.

The salts in order from weakest to strongest lattice energy are calcium oxide, calcium chloride, sodium chloride, and aluminum chloride.

Aluminum chloride has strongest lattice energy because aluminum share its three valence electrons with three chlorides and form a very stable ion that results in a small size of the Aluminum chloride.

Calcium oxide has the smallest lattice energy because the charge on the ions is 2 cations (Calcium) and 2 anions (oxide) while calcium chloride have 2 cations and one anion.

Hence, the correct answer is "1324".
