Question

Elements X and Y have electronic configuration-
X-2,8,6
Y-2,8,3
(a)Which of them is a non-metal and why?
b) To which periods of Modern Periodic Table do each of these
elements belong?
c) Compare the atomic radius of elements X and Y and explain your
answer.​

Answer 1

Explanation:

X is a non metal because it present in oxygen family

2,8,6 = sulpher(16)

b) both occupy in 3 period of modern period table

c) element X have more electronegativity than Y because

Y =2,8,3 it is loosely bonded hence the radius is greater than the component X
