The valencies of elements X and Y will be 1 and 3.
Explanation:
- Valence is defined as the greater number of atoms that are univalent combining with an element’s atom, or a fragment or with a substitute element.
- Another definition of valence has been made recently. It says that the valence is the difference between the number of electrons in a free atom’s valence shell and the number of electrons that are non-bonding. It can also be defined as the sum of the number of bonds and the formal charge.
