Concept explainers
Interpretation:
The number of orbitals in a subshell which are designated by the quantum numbers
Concept Introduction:
Quantum Numbers
The distribution of electron density in an atom is defined by Quantum numbers. They are derived from the mathematical solution of Schrodinger’s equation in the hydrogen atom. The four types of quantum numbers are the principal quantum number (
Principal Quantum Number (
The size of an orbital and the energy of an electron are specified by the principal quantum number (
Angular Momentum Quantum Number (
The shape of the atomic orbital is given by the angular momentum quantum number (
Magnetic Quantum Number (
The orientation of the orbital in space is given the magnetic quantum number (
There is one possible
There are three
There are five
There are seven
For a particular
To find: Get the number of orbitals in a subshell which are designated by the quantum numbers
