Respuesta :

well first you can not go to the 2nd energy level without the first so the first takes up 2 electrons leaving you 5 electrons and the recommended amount is 8 electrons so you would have 5 electrons left

Answer:There are 5 electrons present in the second energy level.

Explanation:

The electronic configuration an element with 7 electrons is give as:

[tex][X]=1s^22s^22p^3[/tex]

Second energy level means that the second principle quantum number.

There are 2 electrons in first energy level and 5 electrons present in the second energy level.
