Question

what will be the maximum nom of electrons in the outermost shell of an atom having atomic number 36

Answer 1

Answer :-

8 Electrons

Explanation :-

The atomic number of the element is 36.

Its Electronic configuration can be written as:

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶

Here the number written as base indicate the number of shells and the numbers written on top represent the number of electrons.

From above configuration the total number of electrons in each shell can be written as:

• For 1st shell:

2 electrons

• For 2nd shell:

2 + 6 electrons = 8 Electrons

• For 3rd shell:

2 + 6 + 10 Electrons = 18 electrons

• For 4th shell:

2 + 6 electrons = 8 Electrons

So, the maximum number of electrons in each shell would be:

→ 2, 8, 18, 8

As we can observe from above,

The maximum number of electrons in the outermost shell = 8
