Principal Quantum Number

Postby Wilson 2E » Sat Oct 19, 2019 10:36 am

How is the Principal Quantum Number (n) calculated for a certain atom? Is it based off of the period of an element? If so does atom excitation affect n?

The principal quantum number is the shell or energy level that an electron is located on. It is calculated by looking at which period the element is located in. We find the principal quantum number of the atoms in their ground state, so I do not think we have to worry about atom excitation affecting n.

I agree with what was said above.

The Principle quantum level is the shell or energy level of an electron at ground state. At ground state electron's aren't excited and jumping energy levels.

The principle quantum number is "calculated" depending on the energy level that the electron is on. We can find it by looking at the period the element is on. As for atom excitation, I'm not too sure about that either...
