Question

Elements X and Y have electronic configuration-
X-2,8,6
Y-2,83
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

Answer:

1) Y is non metal

Explanation:

because it is not stable by 5 electrons

Answer 2

the element X is Sulphur and. element Y is aluminium

the element X is a non metal because it has 5 electrons in it's valence she'll which make it unstable

both X and Y belongs to 3rd period .

atomic radius of element X is greater than element Y bcz x has more electrons in it's orbitals as compared to Y

there is a just neglectly difference in their atomic radius

hope u will satisfied
