Orbitals are the region around a nucleus where there is a high probability of locating an electron. There are 4 kinds to be aware of now:
An s-orbital refers to an orbital spherical in shape. There is only one type of s-orbital.
A p-orbital refers to an orbital along a single axis. There are three kinds of p-orbitals:
The subscript refers to the axis along which the orbital takes place.
A d-orbital refers to an orbital along two axes. There are 5 kinds of d-orbitals:
Information on this is not needed for now. Just note that this is very rare and that there are 7 kinds of f-orbitals.
Each orbital has enough room for no more than 2 electrons.
A subshell is a group of (degenrate) orbitals. A p subshell, for example, will refer to \(p_x\), \(p_y\) and \(p_z\) orbitals. The types noted above are the respective s-subshells, p-subshells, d-subshells and f-subshells.
The same type of orbit, but in different directions.
This is simply the sum of the total electrons that can fit into a subshell. Remember that an orbital can have no more than 2 electrons. Hence, if the p-subshell (as an example) as 3 types of orbitals, then a total of 6 can fit in the subshell.
Maximum electrons: 2
Maximum electrons: 6
Maximum electrons: 10
Maximum electrons: 14
