Had the eletrons lined up in a plane (like solar system), would our world be 2d??
Question:
Answer:
The individual electrons do not travel in planes or anything resembling a planetary orbit. Each electron associated with an atom "occupies" a space whose shape depend on how many other electrons are associated with the same atom. "Occupies" is in quotes because it is only an approximation of the situation. In a sense, any particular electron inhabits the entire universe, but with a much higher probability of being found in certain regions than in others. If you made a really sophisticated graph of the probable locations of the electron, using an infinitely large clear crystal, and staining it some shade of black, with the darkness/opacity of the black depending on the probability of finding the electron there, you would have a picture of the space "occupied" by the electron, sometimes called an electron cloud. For the single atom around a hydrogen atom, the cloud would be a spherical blob, very dark around the nucleus, getting somewhat transparent further from the nucleus, and getting fainter, but never completely clear as you moved further from the nucleus. The shape of the clouds around a helium atom are somewhat like two tear drops, with their pointy ends near the nucleus. The shapes of the clouds are different for different elements, and they are changed when an atom is part of a molecule with other atoms. But the clouds are never planar.
no because the electrons themselves have three dimensions.
