a) A covalent compound is formed
b) Chlorine becomes a negative ion
c) The chemical formula is CaCl2
d) Calcium transfers electrons to the chlorine atoms
e) The subscript 2, is used to balance the charges

The correct statements about the compound calcium chloride are Chlorine becomes a negative ion, The chemical formula is CaCl₂, Calcium transfers electrons to the chlorine atoms and The subscript 2 is used to balance the charge.

Hence, Option B, C, D and E are correct.

Calcium Chloride

Calcium chloride is a crystalline white substance which is soluble in water. It is the chloride salt of calcium. The chemical formula of calcium chloride is CaCl₂. In calcium chloride, Calcium atom has two valence electrons.

Now lets check all statements one by one

Option (A): Calcium chloride is a ionic compound. Here calcium transfers its valence electrons to both chlorine atoms.

So, statement A is incorrect.

Option (B): In calcium chloride each chlorine atom gains 1 electron and we get a negatively charged ion Cl⁻.

So, statement B is correct.

Option (C): In Calcium chloride the valency of calcium is +2 and the valency of chlorine is -1. So the chemical formula is CaCl₂.

So, statement C is correct.

Option (D): In calcium chloride calcium transfer its two valence electrons to both the chlorine atoms.

So, statement D is correct.

Option (E): In calcium chloride the subscript 2 is used to balance the charge. The subscript show the number of atoms in compound.

So, statement E is correct.

Thus, from the above conclusions we can say that The correct statements about the compound calcium chloride are Chlorine becomes a negative ion, The chemical formula is CaCl₂, Calcium transfers electrons to the chlorine atoms and The subscript 2 is used to balance the charge.

Hence, Option B, C, D and E are correct.
