Electron Configurations

Question 1

What do the n and l define?

Answer 1

Define an orbital designations.

Question 2

What are the 3 rules?

Answer 2

1. Lower energy levels are filled first then higher.(called the Aufbav- building up)
2. An orbital can hold a max of 2 electrons with opposite spin.
3. if two or more degenerate orbitals are available fill each orbital with one electron with the same spin, then go back and fill each orbital with an electron of opposite spin.

Question 3

What does degenerate mean?

Answer 3

orbitals with the same energy level.

Question 4

Which orbitals are degenerate?

Answer 4

2p, 3d, 4f,
