### Subshell vs. Orbital

What is the difference between a subshell and an orbital? Are they the same thing?

### Re: Subshell vs. Orbital

Shells are divided into sub shells based on the l number and sub shells are further divided into orbitals. For example the shell n=2 can have sub shells l=0 which is 2s and l=1 which is 2p. 2s and 2p are further divided into orbitals which is where electrons can be paired up. For example, 2p orbitals consist of the orbitals 2px, 2py, and 2pz. When you draw out electron confutation and write out the lines to draw the electron spins on, each line represents an orbital which is why for 2p you would draw 3 lines.

### Re: Subshell vs. Orbital

They're different, but closely related. A subshell is a subdivision of its shell and is what we label as s, p, d, f, g... etc. The subshell has its own subdivisions, the orbitals, which are the clouds where electrons most likely are. Therefore each subshell can have multiple orbitals (the quantity depends on which subshell we're talking about).
Ex: The subshell 3p (energy level n is 3, subshell is p) can have up to three orbitals, px, py, and pz.

A subshell is determined by the l value, and an orbital is determined by the ml value.

### Re: Subshell vs. Orbital

An orbital is a subsection under a subshell. A subshell is recognized based off of the l value: 0=s, 1=p, etc. Then within these, each sub shell has certain orbitals with s having 1, p having 3, d having 5, and f having 7, where each orbital has 2 electrons paired based on their spin state.

Shells are divided into subshells, which are further divided into orbitals. The principle quantum number n gives the shell, while the angular momentum number l gives the subshell. The last main quantum number, ml, which is the magnetic quantum number, gives the orbital of the electron.

### Re: Subshell vs. Orbital

Electron shells are divided into subshells and subshells are divided into orbitals. In terms of quantum numbers, n denotes the shell, l denotes the subshell, and ml denotes the orbital. Each orbital typically houses 2 electrons of opposite spin./

It is also important to note that the numbers of subshells and orbitals will be different. For an "n" shell, there will be "n" numbers of subshells. From "n", we can figure out "l". Then, there will be "2l+1" numbers of orbitals.

n correlates to the shell; l correlates to the subshell; ml correlates to the orbital.

Could you help me understand how to do question 1D. 11? Since the question is asking "How many orbitals are in sub-shells with L equal to (a) 0; (b) 2; (c) 1; (d) 3? Are the answers that I am supposed to be looking for supposed to be the s, p or d numbers?
