Answer is: electron in 2pz orbital.

The principal quantum number is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state, n=1,2,3... n=2 - the second energy level.
The azimuthal quantum number is a quantum number for an atomic orbital that determines its orbital angular momentum and describes the shape of the orbital. l = 0,1...n-1, when l = 1, that is p 
subshell.

The magnetic quantum numberml, show orbital in which the electron is located, ml = -l...+l, ml = 0  is pz orbital.

The spin quantum numberms, is the spin of the electron; ms = +1/2 or -1/2.
