The magnetic quantum number is denoted by letter `m`, and for a given value of `l`, it can have all the values ranging from `-l` to `+l` including zero. For a given `l`, `m` has `2l+1` values. For example, if `l=2`, m can have values, i.e., `m=-2,-1,0,+1,+2`. This implies that there are five different orientations of the d-subshell. In other words, d-subshell has five d-orbitals.
Which of the following is correct for `2p`-orbitals?
`n=1,l=2`
`n=1,l=0`
`n=2,l=0`
`n=2,l=1`
