Question

what are quantum numbers

Answer 1

Quantum numbers are a set of values that describe the properties of an electron in an atom. These numbers are used to specify the energy, angular momentum, and orientation of an electron in an atom. The four quantum numbers are the principal quantum number (n), the azimuthal quantum number (l), the magnetic quantum number (ml), and the spin quantum number (ms). These numbers help to define the electron configuration and behavior within an atom.
