What does n stand for in physics?

Answer 1

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.

Answer 3

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.

Answer 4

There are a number of things that n stands for in physics. Some of the common ones include nano, refractive index, principal quantum number and many more.

Answer 5

In Bohr's atomic model, the "N" designates a principal quantum number.

Answer 6

the principal quantum number

Answer 7

it stands for neutron.

Answer 8
