When n = 3, l= 0, 1, 2 (l takes on three values and thus there are three possible subshells)

four possible combinations

The angular momentum quantum number, signified as (l), describes the general shape or region an electron occupies—its orbital shape. The value of l depends on the value of the principle quantum number n. The angular momentum quantum number can have positive values of zero to (n − 1). If n = 2, l could be either 0 or 1.

Nine values of ml are possible for an electron with orbital quantum number l = 4.

Question : The total number of possible values of magnetic quantum number for the value of l = 3 is. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. When l= 3, m = -3, -2, -1, 0, +1, +2, +3, i.e., there are 7 values for m.

1 Expert Answer ml goes from -l to +l so if l = 0, ml can only be 0. The number of orbitals will be 1, but the value of ml will be 0.

For n = 3, l = 0, 1, 2 For l = 0 ml = 0 For l = 1 ml = -1, 0, or +1 For l = 2 ml = -2, -1, 0, +1, or +2 There are 9 ml values and therefore 9 orbitals with n = 3.

l=3

Given n, the value of l can be any integer from zero up to n − 1. For example, if n = 4, then l can be 0, 1, 2, or 3. Figure 1. The ground state of a hydrogen atom has a probability cloud describing the position of its electron.

Answer. The maximum value of L for n = 5 will 4.

7 values

2 electrons

Since each orbital can hold a maximum of two electrons, the number of electrons that can share the two quantum number n=3 and ml=−2 will be equal to 2 , each having opposite spin.

four sub

14

If l = 3 then the magnetic quantum number m takes the values -l….. 0….. +l . As you can see this means there are 7 orbitals, which in this case will be the 5f which can hold up to 14 electrons.

In your case, n=5 designates an element located in period 5 . Next, the angular momentum quantum number, l , tells you the subshell in which the electron resides. The subshells are equivalent to the blocks of the Periodic Table. In your case, l=2 designates an electron located in the d block of the Periodic Table.

two

An n = 5 means that the electron is at the 5th energy level while an l = 3 means that the shape of the subshell is that of an f subshell. Thus, the notation implies that it is a 5f subshell. The answer is choice c.
