2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
There is only one 2s orbital in an atom.
It is a mixed number.

The 2s sublevel can hold a maximum of 2 electrons.
The difference between the number of 2s and the number of 4s in a sum.
To find how many 2s are in a number, you need to divide it by 2. In this case we have 232, so do: 232/2 = 116. Therefore there are 116 twos in 232.
