Tyson draws a model to show how the particles in a liquid appear. Which model (or models) above could be Tyson's drawing of particles in a liquid? -see picture reference sheet.

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

Ions gain or lose electrons
