What is the valency of the compound calcium carbonate?
The valency of calcium carbonate is 2. Calcium has a valency of 2 as it can lose two electrons to form a stable cation, and carbonate has a valency of 2 as it can accept two electrons to form a stable anion.
What is the valency of oxygen?
Oxygen has a valency of 2. This means that it can form up to two bonds with other elements in chemical compounds.
How can you explain the formula Fe3O4 if Fe has the valency 2 and 3 only?
The formula Fe3O4 is an empirical formula, and a more nearly structural formula is FeO.Fe2O3, which shows valency 2 in its first part and valency 3 in its second part. Two-thirds of the iron cations have valency 3 and the others valency 2, combined in a single crystal structure.
Why is valency of sulphate -2?
The valency of sulfate ion (SO4^2-) is -2 because sulfur contributes a charge of +6 and each oxygen contributes a charge of -2, resulting in a total charge of -2 for the sulfate ion. This allows for the ion to form stable ionic compounds with metals and other cations.
What is the valency of copper?
Copper has a valency of +1 and +2, meaning it can form ions with a charge of either +1 or +2.
What is valency of bisulphate?
-1
What is the valency of carbon?
The combining power of carbon is 4. This means that each carbon atom can form 4 bonds.
What is the valency of a sulphate ion?
The valency of a sulfate ion is -2, meaning it has a charge of -2 due to the presence of four oxygen atoms and a sulfur atom. This valency allows the sulfate ion to form compounds with metals and other ions through ionic bonding.
What is the valency of thiosulphate?
The valency of thiosulfate ion (S2O3^2-) is 2. This is because the sulfur atom can form two bonds with other atoms or ions.
What is the Valency of sulfur?
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
What is the valency of trioxide?
S = +6 valency O = -2 valency
Does hydroxide have valency?
Yes, hydroxide has a valency of 1. So sodium hydroxide - NaOH - is a compound with Na having a valency of 1 and hydroxide having a valency of 1. For calcium hydroxide, in which calcium (Ca) has a valency of two (2), the formula is Ca(OH)2.
