1.	The valency of aluminium is 3. Write the valency of other radicals present in the following compounds.(a) Aluminium chloride(b) Aluminium oxide(c) Aluminium nitride(d) Aluminium sulphate
Answer» (a) Aluminium chloride — (AlCl₃) here valency of Al is 3. Other radical – Chloride (Cl^-) Valency of chloride = 1 (b) Aluminium oxide — (Al₂O₃) Here valency of Al is 3 Other radical presents = oxide (O^2-) Valency of O^2- = 2 (c) Aluminium nitride — (Al N) Here valency of aluminium = 3 Another radical = Nitride (N^3-) Valency of nitride (N^3-) = 3 (d) Aluminium sulphate — Al₂(SO₄)³ Here valency of aluminium is 3 Another radical = Sulphate (SO ₄^2-) Valency of (SO₄^2-) = 2

The valency of aluminium is 3. Write the valency of other radicals present in the following compounds.(a) Aluminium chloride(b) Aluminium oxide(c) Aluminium nitride(d) Aluminium sulphate

Answer»

(a) Aluminium chloride — (AlCl₃) here valency of Al is 3.

Other radical – Chloride (Cl^-)

Valency of chloride = 1

(b) Aluminium oxide — (Al₂O₃)

Here valency of Al is 3

Other radical presents = oxide (O^2-)

Valency of O^2- = 2

(c) Aluminium nitride — (Al N)

Here valency of aluminium = 3

Another radical = Nitride (N^3-)

Valency of nitride (N^3-) = 3

(d) Aluminium sulphate — Al₂(SO₄)³

Here valency of aluminium is 3

Another radical = Sulphate (SO ₄^2-)

Valency of (SO₄^2-) = 2
