there exists a g ∈Gsuch that f1g = f2. 132 neutrons and protons, and by introducing additional quantum numbers, we will be able to. group these particles into 

Atomic mass of Ag=108. Atomic mass though is the SUM of protons and neutrons in an atom's nucleus. Atomic mass (Ag)=protons+neutrons. And as atomic mass=108, protons=47 that means . neutrons=atomic mass-protons==> neutrons=108-47=61. So an atom of Silver(Ag) has. Atomic weight: 107,8682.

Here we measure protons and, for the first time, neutrons knocked out of medium-to-heavy nuclei by high-energy electrons and show that the fraction of high-momentum protons increases markedly with the neutron excess in the nucleus, whereas the fraction of high-momentum neutrons decreases slightly.

Since silver silver 's atomic number is 47 47, Ag Ag has 47 47 protons. Beginning An atom of silver - 108 contains 47 protons, 47 electrons, and 108 neutrons.

So, if we want, we can write: Mass Number = (Number of Protons) + (Number of Neutrons) For krypton, this equation becomes: 84 = (Number of Protons) + (Number of Neutrons) If we only knew how many protons krypton has, we could figure out how many neutrons it has. Wait a minute Neutrons, with protons and electrons, make up an atom.Neutrons and protons are found in the nucleus of an atom. Unlike protons, which have a positive charge, or electrons, which have a negative charge, neutrons have zero charge which means they are neutral particles.Neutrons bind with protons with the residual strong force.. Neutrons were predicted by Ernest Rutherford, and discovered by James Drag protons, neutrons, and electrons onto the atom template to make a neutral atom of Lithium-6 and give the isotope symbol for this atom. Now remove one electron to make an ion and give the symbol for the ion you have created. Determine the number of protons, neutrons, and electrons in the following isotopes that are used in medical diagnoses: Protons and neutrons are made of smaller particles called quarks that are bound together by the strong interaction, which is one of the four known forces of nature: strong force, electromagnetism 2015-12-21 However at the densities in a neutron star, not only can the degenerate electrons have sufficient energy to instigate this reaction, their degeneracy also blocks neutrons from decaying back into electrons and protons. The same is also true of the protons (also fermions), which are also degenerate at neutron … Proton and Neutron Beam Therapy.

Each atom has a charged sub-structure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons.

Well smaller elements the protons and neutrons are not arranged in sphere but more like disk in the nucleus. Once the element get larger the protons and neutrons are arranged in sphere like structure because of proton repulsive forces and the limited amount of neutrons to block the repulsive force.
