उत्तर

Element X has 2 electrons in its M shell.

The electronic configuration would be 2, 8, 2.

So, element X is Mg (12).

Element Y has 7 electrons in its third orbit.

The electronic configuration would be 2, 8, 7.

So, element Y is Cl (17).

  1. MgCl2
  2. The nearest inert gas electronic configuration for element X is 2,8, while that for element Y is 2,8,8.
  3. Orbital diagram showing the formation of the compound between X and Y:

Magnesium chloride:
