Question

What are the quantum numbers necessary to specify a `5p` subshell?

Answer 1

`n=5`
`l=1`

Explanation:

As you know, quantum numbers are sused to describe the exact location and spin an electron can have in an atom.

A total of `4` quantum numbers are used for this purpose, with every electron that's part of a given atom having a unique set of quantum numbers associated with its position ans spin.

Now, the principal equantum number, `n`, gives you the energy level on which you can find an electron.

Each energy level contains a specific number of subshells, given the possible values the angular momentum quantum number, `l`, can take.

For example, the second energy level is characterized by `n=2`. As you can see in the table, `l` can take values rnging from `0` to `n-1`.

This means that the second energy level will have a total of `2` subshells.

In your case, the energy level is given by the number that's placed in front of the letter p, which denotes a specific subshell.

So, the principal quantum number, `n`, for the 5p-subshell is `color(green)(n=5)`.

Now, the any p-subshell is characterized by `l=1`. Similarly, any s-subshell is characterized by `l=0`, any d-subshell by `l=2`, and so on.

Therefore, the value of angula momentum quantum number will be `color(green)(l=1)`.
