प्रश्न
An element has an atomic number 12. How many electrons will be present in the K, L and M energy shells of its atom?
उत्तर
Electronic configuration of element with atomic number 12 is:
\[\underset{2}{\text{ K }}\underset{8}{\text{ L }}\underset{2}{\text{ M }}\]
There will be 2 electrons in the K shell, 8 electrons in the L shell and 2 electrons in the M shell of its atom.
