If most of the space in an atom is empty,  then why do things collide instead of just passing through each other?
Science: If an atom is mostly empty space, do things ever truly touch each other?
Would an atom explode if you split it? Are all atoms the same? Will the nucleus of an atom move inside the atom when an electric field is applied? Theoretically, is it possible for an atom to lose or expel all of its electrons? If so what happens to its nucleus? How would the world be different if we never split the atom? Can a atom of an element and its molecule be the same? Science: Why can't hydrogen atoms form an ionic bond? How different would the world be if we had never split the atom? Why did atoms form? How often do electrons collide with the nucleus of an atom? Why don't atoms' electrons fall into the nucleus? When two objects touch each other can we consider the two forces getting in balance as the contact (touch) process? Is an atom a solid , liquid or gas ? Or is it none ? Are we really alive if we are made of atoms? Will atoms in the same orbital have the same energy in all the elements? Why do electrons repel each other? If our bodies consist of atoms which have electrons why don't we feel the repulsive force between us and things although it also have electrons in it's atoms? Are all atoms elements? Could two planets touch each other and survive? Could one single atom, of any element, ever kill a human being in some bizarre situation? Why the atoms become neutral when it shares electron ? If we could travel at the speed of light and in time? How can we make sure that none of our body atoms get left behind? Is electron spinning or disappear/appear around the nucleus? Can an electron have zero distance to the nucleus? If yes then E=mv^2/2 - Ke^2/r will be there infinite energy? Maybe when an atom is fully shrinked? Even if opposite charges repel each other why are all the protons attached at the same place in an atom? We have a lot of fancy imagination about electron orbitals, yet an atom as observed under SEM/TEM always takes form of ordinary sphere, Why? Why atoms becomes neutral when it shares electrons? Is there evidence of the strongly interacting dark matter that fills 'empty' space every time a double slit experiment is performed? Is it what waves? When an atom of Na and Cl bond to each other, do they not create bonding and anti-bonding orbitals? Why does an electron move around the nucleus?
