Answer:

  • zero

Explanation:

[tex]m_l[/tex]     is the magnetic quantum number.

The only possible value for the magnetic quantum number for an electron in an s orbital is 0.

The first three quantun numbers are:

  • n: principal quantum number. It may have positive integer values: 1, 2, 3, 4,5, 6, 7, ...

  • [tex]l[/tex] : Azimuthal or angular momentum quantum number. It may have integer values from 0 to n - 1.

       This quantum number is related to the type (or shape) of the orbital:

        For s orbitals [tex]l=0[/tex]

        For p orbitals [tex]l=1[/tex]

        For d orbitals [tex]l=2[/tex]

         For f orbitals [tex]l=3[/tex]

In this case, it is an s orbital, so we have [tex]l=0[/tex].

  • [tex]m_l[/tex] , the third quantum number can have integer values  [tex]{from-l}[/tex]   to    [tex]{+l}[/tex]

       Since, for the s orbitals  [tex]l=0[/tex] , the only possible value for [tex]{m_l}[/tex] is zero.
