please explain how to figure out subshells

The number of subshells is the same as N.
If N = 1 we have 1 subshell
If N = 2, we have 2 subshells, the s and p
If N = 3, we have 3 subshells, the s, p, and d.
If N = 4, we have 4 subshells, the s, p, d, and f.

If this isn't exactly what you want, please be more specific and post again. Thanks.

To figure out the number of subshells, you need to know the value of N. N represents the principal quantum number, which determines the energy level and size of an electron's orbit in an atom. Each energy level can have multiple subshells.

The number of subshells is equal to the value of N. For example:

- If N = 1, then there is only one subshell.
- If N = 2, then there are two subshells: the s subshell and the p subshell.
- If N = 3, then there are three subshells: the s subshell, the p subshell, and the d subshell.
- If N = 4, then there are four subshells: the s subshell, the p subshell, the d subshell, and the f subshell.

So, to figure out the number of subshells for a given N value, simply count the subshells based on the rules mentioned above.

Hope this helps! Let me know if you have any further questions.
