The angular momentum quantum number (l) ...

The angular momentum quantum number `(l)` does not tell us the________of the orbitals.
(i) size (ii) shape
(iii) orientation (iv) sublevel

A

`(i),(ii),(iv)`

B

`(i),(iii)`

C

`(ii),(iv)`

D

`(i),(iii),(iv)`

Text Solution

Verified by Experts

The correct Answer is:
B
`l` designates the shape of the region in space that an electron occupies. Within a shell (defined by `n`), different sublevels are possible, each with a characteristic value of `l`.
