Question

Plzzz tell this ques !!

I will mark effective answer as brainliest answer!!

It's Emergency

Answer 1

Electronic configuration of X

K L M

2 8 2

Electronic configuration of Y

K L M

2 8 6

X belong to period 3( no of shells =3)

X belong to group 2(valence electron=2)

They will form electrovalent bond because Y will take 2 electrons and X will donate 2 electrons to attain stable configuration

Answer 2

X= 2,8,2. This is the electronic configuration

Y=2,8,6

Element X belongs to the 2nd group and 3rd period

Element y belongs to 6th group and 3rd period

The bond between x and y will be ionic bond or electrovalent bond

Hope it helps....
