Question

hiiiiiii...........hw electrons r divided according to s, p,d,f. ...???!!!mention properly with detailed explanation ...ty

Answer 1

s, p, d, f and so on are the names given to the orbitals that hold the electrons in atoms. These orbitals have different shapes (e.g. electron density distributions in space) and energies (e.g. 1s is lower energy than 2s which is lower energy than 3s; 2s is lower energy than 2p).

Answer 2

in the s shell there are 2 electrons
Then there are 6 in the p shell 
Then in the d shell there are 10 
While in f there are 14
They are all divided equally using hund's rule, pauli's excrusion principle and afabadu's principle
