If an element has 3 electrons how many of them will be in the second energy level?

The correct answer is:

One

If an element has three electrons two of them will be in the first energy level and one of them will be in the second energy level. This is because the first energy level of an element can hold a maximum of two electrons.

There will be one electron in the second shell

The number of electron in a particular shell are given by the formula 2n² where n shows the number of shell.

So according to the formula

1st shell will have 2 electrons

2nd shell will have 8 electrons

Now if total electrons are 3 then 2 will be accommodated in the first shell and the remaining one will go to the second shell.
