The meaning of PROTON is an elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electro
. It therefore seemed desirable to find whether matter in which there is an excess of neutrons is electrically neutral. We have found that the charge on an argon atom (18 protons, 18 electrons and 22 neutrons) is not greater than 8×10−20eand that on a nitrogen molecule (14 protons, ...

The neutron-proton charge-exchange polarization has provided new information to test various theoretical models and exchange degeneracy of ρ and A 2 trajectories. The small polarization which is consistently negative and independent of energy at most points is changing our belief that particles like ...
In fact in a nucleus, protons and neutrons will be at great speed between a meson exchange, which the child will be lost when a meson into a proton, proton get a meson when the time will become a neutron . There is no doubt, to be exchanged is the positive charge. As a result of...
The neutron-proton charge exchange scattering cross section is calculated in the Born approximation with a modified one-pion-exchange potential which includes the effects of quark exchange between nucleons. The inclusion of these exchange effects leads to a natural interpretation of the narrow spike ob...
The combined mass of proton and neutron virtually makes the mass of an atom. Unlike electrons, protons do not take part in a chemical reaction. Solved Question for You Q. How do protons determine the charge of an atom? Ans.Charge of an atom completely depends on the number of protons in...
