Question

For an element X it is given that atomic number is equal to 17 and mass number is equal 35.
a) what will be the formula of the compound formed between X above and Y having valency 3?

Open in App

Solution

X has atomic number 17, so it is Cl. Y has a valency 3.This means there should be minimum 2 electrons in the s shell. This means that Y has total 5 electrons. Thus the element is Boron. The compound formed between X and Y after exchange of valency will be BCl3. Regards
