Question

what are s,pd,f in chemistry... explain them in easy words....no spam pls guys....I have confusion in it.... how r these formula 2S2 2p1 comes for boron...like that how for other elements...pls explain..... how to determine them easily...​

Answer 1

Explanation:

$\mathfrak{\huge{\orange{\underline{\underline{Answer :}}}}}$

To know what are s,p,d,f in chemistry,you have to know what is an orbit and what is an orbital

Orbit

⇒ the region around the nucleus in which electron revolves is called orbit

Orbital

⇒ The region in the orbit where the probability of finding electron is maximum is called orbital

⇒orbitals are of four types ,they are

● s - orbital

● p - orbital

●d - orbital

● f - orbital

So,s,p,d,f are types of orbitals in chemistry.

To know how 2s²2p¹... come for boron,you should know what is electronic configuration

Electronic configuration

⇒The arrangement of orbitals in increasing order of their energies is called electronic configuration

Important points

●s - orbital can accommodate 2 electrons

●p-orbital can accommodate 6 electrons

●d-orbital can accommodate 10 electrons

●f -orbital can accommodate 14 electrons

Energy order of orbitals

1s<2s<2p<3s<3p<4s<3d<4p...

Ex: Electronic configuration of lithium:-

1s²2s¹(as s-orbital can fit only 2 electrons,electron from 1s orbital jumps to 2s orbital)
