Because principal quantum numbers tells the size and energy of orbital or shells. And also tells the energy of electrons.

It only tells us about electronic configuration and position of electron and not about the nucleons

Quantum number nucleons ko represent Karne k Liye nh hote they just represent energy ,size, shape , orientation,and number of electrons in orbitals and shells and sub shells

One logical reason is ...proton tou increase ho rahy hoty hyn lakin principal quantum number same hota hay ... For example: Li,Be ,B,C,N,O has same principal quantum number but there number of protons increase respectively

Got the point....Thank You
