The foundation of the question ” Why do electrons not collide with protons?” comes from the Rutherford planetary model of an atom. This is an overly simplified model of an atom as a central dense nucleus consisting of protons and neutrons, with electrons revolvin...
Molecules contain atoms and atoms are the smallest units of matter that retain the properties of the chemical element. The three basic subatomic particles are neutrons, protons, and electrons. It is within the atom that we encounter the elementary charge. Electric charge is carried by the ...
