Answer 1

Answer:

Covalent bond forms where there is less difference of electronegativity. So, Y and Z atoms will form covalent bonds.

Ionic bond forms where there is large difference in electronehativities. X and Z can form ionic bond because X has to donate 2 electrons and Z has to gain 2 electrons to achieve noble gas configuration.
