List two non-metal elements that combine with three hydrogen atoms to satisfy the octet rule

Nitrogen as in NH₃. Phosphorous as in PH₃. Explanation

Hydrogen is in group 1. It is one electron away from the next noble gas element. It would form one single covalent bond when it bonds to nonmetals.

A nonmetal atom will gain three extra electrons when it bonds to three hydrogen atoms. For the molecule to be stable, that nonmetal atom should be three electrons away from the next noble gas element. Each of the atoms in question should contain 8 - 3 = 5 valence electrons when neutral. Which column on a periodic table contains such elements?
