# What values of m are permitted for an electron with #l = 2#?

##### 1 Answer

Possible

#### Explanation:

There are four quantum numbers: the principle quantum number,

The

angular momentum quantum number,#l# , describes the shape of the subshell and its orbitals, where#l=0,1,2,3...# corresponds to#s, p, d, # and#f# subshells (containing#s, p, d, f# orbitals), respectively. Each shell has up to#n-1# types of subshells/orbitals.An angular momentum quantum number of

#l=2# describes a#d# subshell.The

magnetic quantum number,#m_l# , describes the orientation of the orbitals (within the subshells) in space. The possible values for#m_l# of any type of orbital (#s,p,d,f...# ) is given by any integer value from#-l# to#l# .

Therefore, given
