The allowable combination for the atomic orbital is n=4, l=2, =2.
Three quantum numbers specify an atomic orbital:
- The principal quantum number, n, which is a positive integer, describes the relative size of the orbital and its distance from the nucleus.
- l is the angular momentum quantum number that is related to the shape of the orbital; l is an integer from 0 to n-1 (so n limits l ),
- is the magnetic quantum number that prescribes the three-dimensional shape of the orbital around the nucleus;
values are integers from -l to =l(l limits ml)
For n = 4, l can four values: 0, 1, 2, and 3. To be consistent with =+2the l value must be higher than 1. There are two l values that are consistent with n and
values: l= 2 or 3
Therefore, the allowable condition is n=4, l=2, =2

The mass of 63 ml sample : 79.38 g
<h3>Further explanation</h3>Given
20 ml and 25.2 g of glycerol
Required
The mass of 63 ml sample
Solution
Density is the ratio of mass per unit volume
Density formula:
Density of glycerol :
= m : V
= 25.2 g : 20 ml
= 1.26 g/ml
Mass of 63 ml sample :
= density x volume
= 1.26 g/ml x 63 ml
= 79.38 g
