Quantum numbers are numerical values that describe the properties of atomic orbitals and the electrons in those orbitals. They are essential for understanding the arrangement of electrons in atoms and the resulting chemical behavior of elements. There are four primary quantum numbers: principal (n), azimuthal (l), magnetic ($m_l$), and spin ($m_s$). Here is the chart
