Question

what is SPDF cell snd define its structure

Answer 1

s=2,p=6,d=10,f=14,electro configuration

Answer 2

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).
