1. QUESTION:
How many ways can the magnetism generated by the orbital motion of an electron in a 3p orbital be oriented? A. 1, B. 3, C. 5, D. 7
Magnetism is due to circular type of motion of a charged particle. Each possible value of the magnetic quantum number (ml) corresponds to one way that the magnetism generated by the motion of an electron around the nucleus can be oriented.
For an electron in a 3p orbital: l=1, and the allowed values of ml are: -1, 0, +1. Since there are 3 possible values of ml, there are 3 ways.

Any type of circular motion involving a charged particle,…
such as the motion of an electron around the nucleus,…
generates a magnetic field.
The number of ways that the magnetism due to the motion of an electron around the nucleus is given by the number possible
values of the magnetic quantum number em sub ell.
CLICK For an electron in a p orbital, the orbital quantum number ell is equal to one, …
In this case, there are three possible values for the magnetic quantum number….-1, 0, and +1.
Therefore, there are three ways that the magnetism can be oriented.
