Identify the azimuthal quantum number \( l \) for the given subshell. For an \( f \) subshell, \( l = 3 \).
Recall that the magnetic quantum number \( m_l \) can take integer values from \( -l \) to \( +l \), including zero.
Write down the possible values of \( m_l \) for \( l = 3 \): \( -3, -2, -1, 0, +1, +2, +3 \).
Count the total number of possible \( m_l \) values. Since it ranges from \( -l \) to \( +l \), the total number is \( 2l + 1 \).
Calculate \( 2l + 1 = 2 \times 3 + 1 \) to find the number of allowed \( m_l \) values for the 5f subshell.
