What is the maximum number of electrons in an atom whose highest-energy electrons have the principal quantum number n=3?

Since you have n=3 then that means that the highest electron configuration it can get up to is 3p6.

This is the same as Argon, which has atomic number 18, and that means it can have 18 electrons.

  • Another way to solve this is just 2n^2. I hope this helps! Leo commented about 1 year ago

Since n=3, the highest energy it can hold is 18

18

n=3 means 3s^2 3p^6 3d^10 this adds up to a maximum of 18 electrons
