(I) MO is the formula of metal oxide M.
∴ Valency of M = 2
Formula of its :-
(a) Chloride
Valency of Chlorine = 1
M² Cl¹
= MCl₂
Formula of its chloride = MCl₂
(b) Hydroxide
Valency of Hydroxide = 1
M² OH¹
= MOH₂
Formula of its hydroxide = MOH₂
(c) Nitrate
Valency of nitrate = 1
M² (NO₃)¹
= M(NO₃)₂
Formula of its nitrate = M(NO₃)₂
(d) Carbonate
Valency of carbonate = 2
M² CO₃²
= MCO₃
Formula of its carbonate = MCO₃
(II) MCL is the formula of the chloride of Metal M.
∴ Valency of M = 1
Formula of its :-
(a) Oxide
Valency of oxide = O²
M¹ O²
= M₂O
Formula of its oxide = M₂O
(b) Chloride
Valency of chloride = 1
M¹ Cl¹
= MCl
Formula of its chloride = MCl
(c) Nitrite
Valency of nitrite = 1
M¹ NO₂¹
= MNO₂
Formula of its nitrite = MNO₂
(d) Peroxide
Valency of peroxide = 2
M¹ O₂²
= M₂O
Formula of its peroxide = M₂O
(e) Bicarbonate
Valency of bicarbonate = 1
M¹ HCO₃¹
= MHCO₃
Formula of its bicarbonate = MHCO₃
(III) MOH is the formula of the hydroxide of Metal M.
∴ Valency of M = 1
a. oxide
Valency of oxide = 2
M¹ O²
= M₂O
Formula of its oxide = M₂O
b. carbonate
Valency of carbonate = 2
M¹ CO₃²
= M₂CO₃
Formula of its carbonate = M₂CO₃
c. Bi-sulphate
Valency of bisulphate = 1
M¹ HSO₃¹
= MHSO₃
Formula of its bisulphate = MHSO₃
d. Sulphite
Valency of sulphite = 2
M¹ SO₃²
= M₂SO₃
Formula of its sulphite = M₂SO₃
e. Nitride
Valency of nitride = 3
M¹ N³
= M₃N
Formula of its nitride = M₃N
1. If MO is the formula of Metal Oxide, it means that the valency of M is 2 since Valency of oxygen is 2
- Formula of its chloride:
M has valency 2 and
Chloride (Cl) has valency -1.
So, the formula of its chloride → MCl₂
- Formula of its Hydroxide:
M has a valency of 2 and
Hydroxide has a valency of -1.
So, the formula of its hydroxide → M(OH)₂
- Formula of its nitrate:
M has a valency of 2
Nitrate (NO₃) has a valency of -1.
Formula of its nitrate → MNO₃
- Formula of its carbonate:
M has a valency of 2 and
Carbonate (CO₃) has a valency of -2
So, formula of its carbonate → MCO₃
- Formula of its sulphate:
M has a valency of 2 and
Sulphate (SO₄) has a valency of -2
So the formula of its sulphate → MSO₄

2. If the formula of chloride of metal M is MCl, then the valency of M is 1 since the valency of Chloride (Cl) is 1.
- Formula of oxide:
M has a valency of 1 and
Oxide (O) has valency of -2.
So, the formula of its oxide → M2O
- Formula of chloride → MCl (already given)
- Formula of Nitrate:
M has a valency of 1 and
Nitrate has a valency of -1
So, the formula of its nitrate → MNO₃
- Formula of peroxide:
M has a valency of 1 and
Peroxide has a valency of 2
So, the formula of its peroxide → M₂O₂
- Formula of Bicarbonate:
M has a valency of 1 and
Bicarbonate has a valency of 1
So, the formula of its Bicarbonate → MHCO₃
_____________________________________________
3. If MOH is the formula of its hydroxide, then metal M would have a valency of 1 because Hydroxide has Valency 1
- Formula of Oxide:
M has valency of 1 and
Oxide has a valency of -2
So, the formula of its oxide → M₂O
- Formula of carbonate:
M has a valency of 1 and
Carbonate has a valency of -2.
So, the formula of its carbonate → M₂CO₃
- Formula of Bi-sulphate:
M has a valency of 1 and
Bi-sulphate (HSO4) has a valency of 1
So, the formula of its Bi-sulphate → MHSO₄
- Formula of Sulphite:
M has a valency of 1 and
Sulphite has a valency of 2.
So, the formula of its Sulphite → M₂SO₃
- Formula of Nitride:
M has a valency of 1 and
Nitride has a valency of -3
So, the formula of its nitride → M₃N
