What is Covalent Bond ?
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.
These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Silicon and nitrogen forms strong covalent bond . This stable covalently bonded material does not readily sinter and cannot be heated over 1850⁰C as it dissociates into silicon and nitrogen.
Therefore, The pair of elements which will form covalent bonds with each other are Si (Silicon) and N (Nitrogen). Hence the correct option is (B).

salt + water. It is called the ionic equation for neutralisation. the acid to form a salt solution.
Explanation:
So what you end up with is you always end up H+ plus OH- yields H2O, because HCl, and NaOH, since they're strong, they fully dissociate. So the Na+, and the Cl - are spectator ions. So with a strong acid and strong base, the net ion equation is always H+ plus OH- yields H2O.
