Question

Which of the following energy levels has the highest energy? And why?

A) 4p

B) 4s

C) 3d

D) 4f

Answer 1

Take a look at the attachment.
From low energy to high:
You start in the left upper corner, so with 1s. then you go to the right untill you cannot go further, that's where you go 1 period lower. So s2, then you go to the right again. You'll see there's 2p next. then 3s, 3p. etc
So which level has the highest energy?

Answer 2

4f ?

Answer 3

yes :)

Answer 4

actually 4f is between 6s and 5d, as in a normal periodic table. And 5f is between 7s and 6d. But still 4f has the highest energy.
