Hi, everybody. I wanted to ask you about the question that really tortured me for quite a long time: Does electrically neutral atom have energy above 0? I mean what would happen if you have measuring instruments and they tell you energy is 0, but the energy of atom is still there-potential energy? Do electrically neutral atoms have/possess any kind of energy field, or any kind of force field that surrounds them, or atoms are truly empty (except the core, the rest, 99.94% of atom is empty)? I'm talking about electric energy, magnetic field, electromagnetic field, quantum field or whatever But is there such thing as being truly empty even if atom is electrically neutral? But as far as I know, 100% nothingness/emptiness does not exist (not even inside of atom), so how to explain the void/emptiness in the atom (I'm talking about those 99.94% that are empty and the rest is the core which is not empty)? Are those 99.94% of the atom truly empty or they are filled with some energy field of force field? Could you say the charge of atom is 0 (when you measure it), but it's still there perfectly balanced in electrons, and protons? Could you say the energy of atom is 0 (when you measure it), but it's still there in electrons, and protons, actually it's only perfectly balanced? Is it true that the electric field of a neutral atom is weak, but is not exactly zero because the atom is not a point particle-i saw this here: http://sciencequestionswithchris.wordpress.com/2013/06/07/why-do-atoms-always-contain-the-same-number-of-electrons-and-protons/ [Broken] Didn't you hear that atom has been seen, literally? http://physicsworld.com/cws/article/news/2013/may/23/quantum-microscope-peers-into-the-hydrogen-atom http://physics.aps.org/articles/v6/58 http://www.newscientist.com/article/mg21829194.900-smile-hydrogen-atom-youre-on-quantum-camera.html Big thanks in advance to all your answers, explanations, time and patience!
