Question

Q Two elements Xand y belong to the
group 14 and 16 respectively in the
same periods compare them with
respect to:
a) The number pf valence electron
b) valency
ç ) electronegative characters
d)size of the atoms.
e) formula of oxide x​

Answer 1

Answer:

a) The valence number of electrons in X is 1 and in Y is 2.

b) The valency of the element is determined by the number of electrons in the outermost shell . Thus, the valency of element X is 1 and Y is 2.

c) Element X is more metallic than Y.

d) The size of element X is more than Y.

e) The formulae of oxide of element X is X
