Answer 1

${\huge{\underline{\boxed{\mathfrak{\fcolorbox{cyan}{red}{Answer:-}}}}}}$

Maximum number of electron in s,p,d,f orbitals are 2 ,6 ,10 and 14 respectively. ... For example we have to find unpaired electron in P(phosphorous) whose atomic numberis 15 then its electronic configurationis as follows 1s^2,2s^2,2p^6 ,3s^2 , 3p^3 number of unpaired electron is 3.
