What is the total number of orbitals associated with the principal quantum number n = 3 ?

The total number of orbitals in a shell having principal quantum number 'n' is

The total number of orbitals in L shell of an atom is

The total number of orbitals in M shell of an atom is

The total energy of a Bohr’s orbit is proportional to (n = Principal quantum number)

Assertion : The maximum number of electrons in the shell with principal quantum number nis equal to 2n^(2) ?. Reason : Two electrons in an orbital have the same value of three quantum numbers n, l and m, but must have different spin quantum numbers.

Write the 4 quantum numbers

Assertion : 2p orbitals do not have any spherical node. Reason : The number of nodes in p-orbitals is given by (n-2) where n is the principal quantum number.

Does the angular momentum of an electron in an atom depend on the principal quantum number (n)?

Represent the orbital with quantum numbers n=1 and l=0
