Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of proton...
At Atomic and Nuclear distances, the non-singular potential explains when a proton and electron form a hydrogen atom, when they form a neutron, and the model predicts the half life of a neutron from quantum tunneling considerations. At atomic distances the model predicts the structure of the ...
Mass of an atom Nucleus- contains most of the mass of an atom –Protons & Neutrons contain most of an atom’s mass Mass of proton = mass of neutron = 1amu –Electrons- 1/2000 th of the mass of a proton Atomic structure Grams are not used to measure mass of atoms because atoms are...
An atom contains protons, neutrons, andelectrons. The nucleus of an atom consists of bound protons and neutrons (nucleons). The negatively charged electrons are attracted to the positively charged protons and fall around the nucleus, much like a satellite is attracted to the gravity of the Earth...

IT is known that, starting with Fermi's expression for the coupling between a heavy nuclear particle and the field of electrons and neutrinos, we get in the second approximation the law for interaction between proton and neutron. This law : (g is Fermi's constant, the best choice for s ...

Since the charge of the proton is a positive one, the number of protons vs. electrons in an atom is important in determining the charge of the atom. There is one atom that has only a single proton and no neutrons: hydrogen. As a neutron has no actual electrical charge, the only charge...
