Question

WHAT ARE QUANTUM NO.? IN BRIEF.

Answer 1

Quantum numbers are descicribe the size energy orentation and postion of electron
1.Principal quantum number (n)
describe size and energy of main shell n has integer values from 1 2 3......for each n value their is one main shell

2.Angular quantum number (l)
descibes size and energy of subshell it has values from 0to nminus 1

Answer 2

Answer:

Quantum numbers describe values of conserved quantities in the dynamics of a quantum system. In the case of electrons, the quantum numbers can be defined as "the sets of numerical values which give acceptable solutions to the Schrödinger wave equationfor the hydrogen atom".
