Question

The number of degenerate orbitals in an energy level of h atom having en=-rh/9

Answer 1

Answer:

3because it belongs to paschen series

Answer 2

The number of degenerate orbitals in an energy level of H atom having energy equal to -Rh/9 is 9.

• The energy of nth shell of a H atom is equal to -Rh/n² .
• Therefore, the given energy level refers to the third shell of the hydrogen atom.
• The third shell of hydrogen has 3s , 3p and 3d subshells having 1 , 3 and 5 orbitals respectively.
• All the three subshells of hydrogen are degenerate since hydrogen atom contains only one electron.
• So, the total number of degenerate orbitals is equal to 9.
