Answer 1

Answer:

Explanation:

What do 4 quantum numbers represent?

To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms). The first quantum number describes the electron shell, or energy level, of an atom. ... The dynamics of any quantum system are described by a quantum Hamiltonian (H).

Answer 2

Answer:

In atoms, there are a total of four quantum numbers: the principal quantum number (n), the orbital angular momentum quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms).
