Expert Answer
Dear student,
The above rules are not applicable in general. Platinum is a transition element and does not follow the above rule. A more general definition applicable for calculation of valency in this case is 'valency or valency number, is a measure of the number of chemical bonds formed by the atoms of a given element.'
