Electron Configuration
How many electrons can fit into each orbital?
How many electrons can fit into each type of subshell?

So how do you remember that?
…You can use a periodic table
But you don’t always have a periodic tableSo you can use quantum numbers
If the principal quantum number equals zero, then there are no orbitals. If the principal quantum number equals one, then the angular momentum quantum number will equal zero, and the magnetic quantum number will equal zero, which means that there is one orbital. Because there is one orbital, this subshell can hold two electrons. If the principal quantum number equals two, then the angular momentum quantum number will equal zero or one, and the magnetic quantum number will equal negative one, zero, or one, which means that there are three orbitals. Because there are three orbitals, this subshell can hold six electrons. If the principal quantum number equals three, then the angular momentum quantum number will equal zero, one or two, and the magnetic quantum number will equal either negative two, negative one, zero, one, or two, which means that there are five orbitals. Because there are five orbitals, this subshell can hold blah blah blah…
In short, the number of orbitals is determined by the magnetic quantum number. Multiply the number of orbitals
by two to get the number of electrons.
But you might not remember that,
So Ponies Disallowed Fingerpointing
So*2 letters*s orbital holds up to two electrons
SO GOOD!
Ponies*6 letters*p orbital can hold maximum of 6 electrons
6 Ponies 6 Letters 6 Electrons
Disallowed*10 letters*d orbital can hold maximum of 10 electrons
No Nicht Ne Non Nie Bu ノー
Fingerpointing*14 letters*f orbital can hold maximum of 14 electrons
