When using the sublevel designation, an atom can have a maximum of 2 electrons.

What is Quantum number?

  • Quantum numbers in quantum physics and chemistry explain the values of conserved quantities in a quantum system's dynamics.
  • Because they can be used to determine an atom's electron configuration and the likely placement of its electrons, quantum numbers are significant.
  • The atomic radius and other properties of atoms, such as ionization energy, are also understood using quantum numbers.
  • The maximum number of electrons that each atom with the specified sublevel designations can hold depends on its energy level.

Calculation of energy level:

For n = 2, I = 1, [tex]m_{l}[/tex] = 0,

Energy level = 2(1) + 1 = 3 sub-orbtials

= -1  0  1  : ( 2 electrons each)

As a result, an atom can have a maximum of 2 electrons using the sublevel designation.
