What are quantum numbers?

Back

Quantum numbers are a set of numerical values that describe the unique quantum state of an electron in an atom, including its energy level, shape, orientation, and spin.

What does the principal quantum number (n) represent?

Back

The principal quantum number (n) indicates the main energy level or shell of an electron in an atom, with values ranging from 1 to infinity.

What does the azimuthal quantum number (l) indicate?

Back

The azimuthal quantum number (l) indicates the shape of the orbital and can take on integer values from 0 to (n-1).

What is the maximum number of electrons in a given energy level?

Back

The maximum number of electrons in an energy level is given by the formula 2n², where n is the principal quantum number.
