Question

List all possible values of the magnetic quantum number ml for a 1s electron:

a) ml = 0
b) ml = -1, 0, 1
c) ml = -2, -1, 0, 1, 2
d) ml = -1

Answer 1

The possible value of the magnetic quantum number (ml) for a 1s electron is 0, as it is determined by the angular momentum quantum number (l), which is 0 for the s orbital.

Step-by-step explanation:

The possible values of the magnetic quantum number (ml) for a 1s electron are determined by the value of the angular momentum quantum number (l). For an electron in a 1s orbital, l is equal to 0, and therefore the possible values for ml range from -l to +l in integer steps. Since l=0 for a s-orbital, this means that the only possible value for ml of a 1s electron is 0.However, differences in range are generally not used to signal a downbeat. Range refers to the span from the lowest to the highest notes an instrument or voice can produce, and while changes in range could potentially happen at any point in the composition, they are not specifically indicative of a downbeat.
