If an element has 3 electrons, how many of them will be in the 2nd energy level?

Hello again!
The energy levels of an atom can be classified as follows:
First level-2 electrons
Second level-8 electrons
Third level-18 electrons
Fourth level-32 electrons

If an atom has 3 electrons, 2 of them will be in the 1st energy level making the 3rd one be on the 2nd energy level. Good luck with your homework!

Alinear relationship would look like a straight line on the graph. it could have a positive negative or 0 slope. so it could be a line potentially going in any direction but it must be perfectly straight.
