- Protons and electrons stick to each other as much as they can, but kinetic energy and quantum mechanics keep them from holding still. Protons and electrons are attracted to each other because the positive electric charge of the proton is attracted to the negative charge of the electron.

Nov 1, 2009 · You can cause - if at very high pressures - electrons essentially to react with protons and turn into neutrons, and this is what happens in neutron stars. A neutron actually isn't stable just lying around in the atmosphere, or in a vacuum.
Feb 22, 2016 · Not only are electrons attracted to protons, electrons radiate away energy when accelerated. A classical electron in orbit around a proton should spiral into the nucleus in a small fraction of a second.
After this discovery, nuclear science and technology started immediately. Figure 15.5.2 15.5. 2: Elements, such as helium, depicted here, are made up of atoms. Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus. Masses for the three subatomic particles can be expressed in amu ...
Jul 29, 2022 · In order to be neutral, an atom must have the same number of electrons and protons. Atoms—and the protons, neutrons, and electrons that compose them—are extremely small. For example, a carbon atom weighs less than 2 × 10 −23 g, and an electron has a charge of less than 2 × 10 −19 C (coulomb).
Aug 26, 2020 · Electrons and protons have electrical charges that are identical in magnitude but opposite in sign. Relative charges of −1 and +1 are assigned to the electron and proton, respectively. Neutrons have approximately the same mass as protons but no charge.
Protons and neutrons are located in the nucleus, and electrons orbit around the nucleus. But we need to know the structural details to understand why atoms react the way they do. Virtually everything we know about atoms ultimately comes from light.
