Solution
The chemical formula of Calcium nitrate:-
The chemical formula of a compound can be defined as the symbolic representation of its chemical composition.
The atomic number of calcium is 20 and its electronic configuration is .
Thus according to the octet rule, we know that, if calcium needs to lose 2 electrons then its outermost shell would have 8 electrons which would make it stable.
On the other hand, nitrate ions have a negative charge .
This means the nitrate ion needs 1 electron to become stable.
So, the calcium atom donates its 2 outermost electrons to 2 nitrate ions.
This makes both the nitrate ion and the calcium atom becomes stable.
Thus the formula of calcium nitrate becomes .
Therefore, the chemical formula of calcium nitrate is
