Electrons and also Sublevels

Principal energy levels are broken down right into sublevels. Theoretically there room an boundless number principal power levels and also sublevels. If you are just starting to study chemistry, you must only be involved with the first 4 sublevels.

You are watching: Give the principal level for a 2 p sublevel.

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

The Principal power Level (the #) just holds the # the sublevels.

Principal power Level# of Sublevels sublevels
222s 2p
333s 3p 3d
444s 4p 4d 4f
555s 5p 5d 5f 5g

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

sublevel# of electrons in each sublevel

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

NOTE-Some Principal power Levels begin to fill before previous persons finish. ex 4s fills before 3d, since 4s has actually less power than 3d. It should fill first.
