To determine the maximum number of orbitals that can be identified with the given quantum numbers, we need to understand the role of each quantum number:$\\$• $n$ is the principal quantum number, which indicates the energy level. Here, $n = 3. \\$• $l$ is the azimuthal (or angular momentum) quantum number, which defines the shape of the orbital. Here, $l = 1. \\$• $m$ is the magnetic quantum number, which specifies the orientation of the orbital in space. Here, $m = 0. \\$For a given $n$ and $l,$ the possible values of $m$ range from $-l$ to $+l. \\$Since $l = 1,$ the possible values of $m$ are $-1, 0,$ and $+1. \\$However, the question specifies $m = 0.$ This means we are looking for orbitals with $m = 0$ only.$\\$For $n = 3$ and $l = 1,$ the orbitals are $3p$ orbitals.$\\$The $3p$ subshell has three orbitals: $3p_x, 3p_y,$ and $3p_z. \\$Each of these orbitals corresponds to a different value of $m: \\$• $3p_x$ corresponds to $m = -1 \\$• $3p_y$ corresponds to $m = 0 \\$• $3p_z$ corresponds to $m = +1 \\$Since we are only interested in $m = 0,$ there is only one orbital that satisfies this condition: $3p_y. \\$Therefore, the maximum number of orbitals that can be identified with $n = 3, l = 1, m = 0$ is $1. \\$This corresponds to Option 1.
