Question

what are Quantum numbers. list the information we get from principal quantum number

Answer 1

each electron in an atom is identified the terms of four Quantum numbers.

1, principal quantum number- it Tell about the mainly Vishal in which the electrons resides. it also give an idea about the energy of shells and every distance between electrons from the nucleus.

2, azimuthal quantum number-it tell about the success (s,p,d,f) it also represent the angular momentum of an electron in the shape of sub shell.

3, magnetic quantum number-it Tell about the number of orbitals and orientation of a subshell.

4, spin quantum number- it indicate the direction of spinning of electrons example clockwise or anticlockwise.

I hope you will understand you will understand quantum number in detail.

Answer 2

hlo dear..

here the ans is..________

A quantum no. is is a value of that is used when describing the energy levela available to atoms and molecules..
there are 4 quantum no.s
1. principal  quantum no.- describes the energy level
2. angular momentum quantum no.- describes the subshell
3. magnetic quantum no.- describes the orbital of the subshell
4. spin quantum no.- describes the spin 

hope my ans helps u buddy ..^-^

plz..make my ans as brainliest if i deserve
