Question

What is the maximum number of electrons that can occupy the n = 2 shell?For a 4s orbital ,what are the possible values of n, l and ml.

Answer 1

`8\text{ electrons}`

Explanations:

Here, we want to get the maximum number of electrons

Mathematically, we have that as:

`N\text{ = 2n}^2`

Now, we simply have to substitute 2 for n

`N\text{ = 2\lparen2\rparen}^2\text{ = 8 electrons}`
