What is the maximum angular momentum Lmax that an electron with principal quantum number n = 2 can have? Express your answer in units of ℏ.

Respuesta :

Answer:

[tex]L_{max} = 1.414 [/tex] ℏ

Given:

Principle quantum number, n = 2

Solution:

To calculate the maximum angular momentum, [tex]L_{max}[/tex], we have:

[tex]L_{max} = \sqrt {l(1 + l)}[/tex]                              (1)

where,

l = azimuthal quantum number or angular momentum quantum number

Also,

n = 1 + l

2 = 1 + l

l = 1

Now,

Using the value of l = 1 in eqn (1), we get:

[tex]L_{max} = \sqrt {1(1 + 1)} = \sqrt 2[/tex]

[tex]L_{max} = 1.414 [/tex] ℏ
