What is the last energy level of N? Mg?
Alexandra [31]

Answer:

2

3

Explanation:

To infer the last energy of the given atoms, we need to write their electronic configuration:

For N = 1S² 2S² 2P³

     Mg  = 1S² 2S² 2P⁶ 3S²  

The energy levels are usually designated as;

   n = 1

   n = 2

   n = 3

   n =4

For N, the last energy level is 2

     Mg, the last energy level is 3

We can also determine this number by the periods the atoms can be found.
