Complete the chemical formula for each ionic compound. Consult the periodic table to help you answer the question. magnesium nitride: Mg N calcium chloride: CaCl

Magnesium Nitride - Mg₃N₂

Calcium Chloride - CaCl₂

1. Magnesium (Mg) has a charge of +2, Nitrogen (N) has a charge of -3.

2. Adjust the subscript on each cation and anion to balance the overall charge.

3. Check that the sum of charge of cation equals the sum of charges of the anions.

Mg: 2(3) = 6

N: -3(2) = -6

The charges cancel out so the formula is .

ii)  1. Calcium (Ca) has a charge of +2, Chloride (Cl) has a charge of -1.

2. Adjust the subscript on each cation and anion to balance the overall charge.

3. Check that the sum of charge of cation equals the sum of charges of the anions.

 Ca: 2(1) = 2

Cl: -1(2) = -2

The charges cancel out so the formula is .

Magnesium Nitride - Mg₃N₂

Calcium Chloride - CaCl₂

Explanation:

Magnesium (Mg) has a charge of +2, Nitrogen (N) has a charge of -3.

Swap the charges and you get Mg₃N₂.

Mg: 2(3) = 6

N: -3(2) = -6

The charges cancel out so the formula is correct.

Calcium (Ca) has a charge of +2, Chlorine has a charge of -1.

Swap the charges and you get CaCl₂.

Ca: 2(1) = 2

Cl: -1(2) = -2

The charges cancel out so the formula is correct.

Hope this helps. :)
