Question

If K and L shells of an atom are full ,what would be the total no.of electrons? a.8 b.10 c.18 d.32​

Answer 1

Answer:

The maximum number of electrons that can be occupied in the K and L-shells of an atom are 2 and 8 respectively. Therefore, if the K and L-shells of an atom are full, then the total number of electrons in the atom would be (2 + 8) = 10 electrons.

Explanation:

I hope it's help you

Answer 2

Answer:

10 electrons

According to rule First shell will only have atmost 2 electrons and the further shells follow the 2n² rule.

2n^2 is d formula used to find the electronic configuration of elements, where n denotes d number of shell.

2 + 2(2)²

2 + 2(4)

2 + 8

10

The element is Neon and has 10 electrons in total.
