Total angular momentum quantum number
Imagine you are spinning a toy top. The faster it spins, the more energy it has. In the same way, small particles like electrons and protons can also spin, which gives them energy.
Now imagine that the toy top can spin in different directions. It can spin clockwise or counterclockwise. Similarly, electrons and protons can spin in different directions as well.
The total angular momentum quantum number is a way to describe the amount of spinning that a particle has. It takes into account both the speed of the spinning (which we call the "angular momentum") and the direction that it's spinning in.
For example, let's say we have an electron that is spinning in a certain direction with a certain speed. We can give it a total angular momentum quantum number to describe how much it is spinning overall.
This quantum number is written as "j" and is calculated by adding together two other quantum numbers: the orbital angular momentum quantum number (l) and the spin quantum number (s).
The orbital angular momentum quantum number describes the shape of the electron's path as it orbits around the nucleus. It can have values of 0, 1, 2, 3, and so on.
The spin quantum number, on the other hand, describes the direction the electron is spinning in. It can have a value of +1/2 or -1/2.
So, to get the total angular momentum quantum number, we add together the orbital angular momentum quantum number and the spin quantum number.
For example, if our electron has an orbital angular momentum quantum number of 2 and a spin quantum number of +1/2, then its total angular momentum quantum number would be 2 + 1/2 = 5/2.
Overall, the total angular momentum quantum number helps us understand the spinning behavior of tiny particles like electrons and protons.
