n is the principal quantum number and represents the energy level or electron shell in which an electron resides.

For example - Say you have an Oxygen atom, which has 8 electrons. It's electron configuration is 1s2 2s2 2p4. The 2 in 2p4 is the principle quantum number, n. The s is another term dealing with angular momentum and the 4 is the number of electrons.

In physics, n generally stands for a number or quantity, such as the index of refraction n in optics or the number of turns in a solenoid coil. It is a variable used to represent a value that may vary depending on the context of the specific physical situation.

Symbols in physics (and most other science) are subject to conventions and one can find many different symbols used for the same thing. The letter n is especially bad since it is not a Greek letter and therefore generally used as a 'dummy' letter.

The letter n is, at least in my experience as a physics student, mostly used for summations.
