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