Question

The chemical formula of calcium chloride is:

• A.
• B.
• C.
• D. None of these

Answer 1

The correct option is A

Compounds are formed by the combination of atoms of more than one element. Atoms combine with each other in whole numbers. This whole number is the combining capacity of the elements.
Step-1: In calcium chloride - We write the symbol of both the elements.
Ca Cl
Step-2: Write down the combining power of the elements.
Step-3: Interchange the combining power, after removing the charge sign to obtain the chemical formula of the compound.

So, the chemical formula of calcium chloride is $CaC{l}_2$.
