YZ
Z2Y3
Z3X2

Answer 1

x=1s²,2s²,

y=1s²,2s²,2p6

z=

Answer 2

Explanation:

Given -

1. Electronic configuration of X is 2,4
2. Y is 2,6
3. Z is 2,8,3

To Find -

• The Formula of the ionic compound is ?

Solution -

Electronic configuration of X is 2,4

Then, it's atomic number is 6

Then, the element is Carbon (C)

And

Electronic configuration of Y is 2,6

Then, It's atomic number is 8

Then, the element is Oxygen (O).

And

Electronic configuration of Z is 2,8,3

Then, It's atomic number is 13

Then, the element is Aluminium (Al).

Then,

The Formula of ionic compound is Z2Y3.

Because Ionic compound is formed between Al and O. Then, The Ionic compound is Al2O3 (Z2Y3).
