The Electron Configuration: Quantum Numbers Video Lessons

Concept:

# Problem: The four quantum numbers most likely associated with the one electron lost in going from P to P+ are:(a) 4, 0, 0, +1/2(b) 3, 1, 1, +1/2(c) 3, 2, 1, -1/2(d) 4, 1, 0, +1/2(e) 3, 3, -1, +1/2

Determine the orbital diagram of P and identify the outermost electron (in quantum numbers) involved when it is transformed to P+

In this matter, the 4 quantum numbers are already shown as n, l, ml and ms

Recall that the quantum numbers that define an electron are:

• Principal Quantum Number(n): deals with the size and energy of the atomic orbital. The possible values for n are 1 to ∞.

• Angular Momentum Quantum Number (l): deals with the shape of the atomic orbital. The possible values for l are 0 to n – 1.

• Magnetic Quantum Number (ml): deals with the orientation of the atomic orbital in 3D space. The possible values for ml are the range of –l to +l.

• Spin Quantum Number (ms): deals with the spin of the electron. The possible values for ms are either –1/2 (spin down) or +1/2 (spin up).
