A- Arrangement of sub shell is given by (n + 1) numbers

B- Filling of electrons in degenerate orbitals is given by Hunds rule

C- Filling of electrons in an orbital is given by Pauli's exclusion principle

D- Two electron in an orbital can have same value of four quantum numbers​

Answer 1

Explanation:

(d) two electron in an orbital can have same value of four quantum numbers

just mark me as Brainliest

Answer 2

D -Two electron in an orbital can have same value of four quantum numbers

Explanation- No two electrons can have the same four quantam numbers. They must have different spin quantam number if they are in same orbital.
