Electrons and also Sublevels

Principal power levels are damaged down right into sublevels. About theory there space an boundless number principal energy levels and sublevels. If you room just beginning to research chemistry, you need to only be came to with the an initial 4 sublevels.

You are watching: What electron sublevel starts to fill after completion of the 5s sublevel?

Each sublevel is assigned a letter. The four you require to understand are s (sharp), ns (principle), d (diffuse), and also f (fine or fundamental). So, s,p,d & f.

The Principal energy Level (the #) only holds that # the sublevels.


Principal energy Level# that Sublevels sublevels
111s
222s 2p
333s 3p 3d
444s 4p 4d 4f
555s 5p 5d 5f 5g

Yes, the fifth energy level stop 5 sublevels and also that critical one would certainly be 5g.

Electrons to fill in energy order (Aufbau Principle) not power level order.

NOTE-Some Principal power Levels start to fill before previous ones finish. ex 4s fills prior to 3d, due to the fact that 4s has less energy than 3d. It need to fill first.
