    You can have one p axis pointing in the x direction, one in the y direction, and one in the z direction. each of these contain two electrons, plus spin and minus spin so there can be a total of 6 p electrons at this level. I guess each two electron p would look like a dumbbell but I do not know what the ring about it means. I suppose it might indicate the level of the orbit.

    All potassium atoms have the same number of protons. Therefore the atomic mass goes up with the number of neutrons 39, 40 , 41

    In my opinion, none of the answer choices for the p orbitals is correct.
