In period 2, elements X is to the right of element Y. Then, find which of the elements have :
i) Low nuclear charge
ii) Low atomic size
iii) High ionization energy
iv) High electronegativity
v) More metallic character

X is to the right of Y. So they will be YX.

  1. Low nuclear charge : Nuclear charge increases from left to right in a period. So Y has low nuclear charge.
    ii) Low atomic size : Atomic size decreases from left to right in a period. So X has low atomic size.
    iii) High ionization energy : Ionization energy increases across a period from left to right. So X has high ionization energy.
    iv) More metallic character : Metallic nature decreases from left to right. So Y has more metallic character.
