Discovery of Neutrons
The whole mass of an atom is due to the nucleus, which means that the nucleus must contain protons equal to the mass of the atom. As the number of protons is equal to the atomic number, the atomic mass should be equal to the atomic number. But for all atoms except hyd..
Nuclear Stability and Neutron/Proton Ratio
It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stable nuclides upto Z = 20, N = 20 i.e., the relat..

  How I can Demonstrate the atomic mass is approximately equal the number of protons + the number of neutrons ?I also presume for the sake of my presentation that matter in general will increase in mass by the same factor that Mr Haramein increased the mass of the proton. 3) The Necessity of Changing the value for the Gravitational Constant, when the Value for the mass of the proton, implying the mass of matter in general, is changed. The gravitation constant was calculated using the standard unit of mass. According to the laws of Algebra, if you change the standard unit of mass, then you need to ...
Question : Determine the number of protons, neutrons and electrons in an ion
52-atomic mass 24- atomic # 3+ charge Cr
Answer : Tiffany, you've asked this same question about forty-eleven times. What's the deal? I think I have figured out your problem. You need to distinguish between the 'atomic mass' and the 'mass number'. The atomic mass in a decimal number that represents the actual mass of an atom. You can also have the average atomic mass (which is printed on the periodic table) which is the weighted average of ALL of the naturally occurring isotopes of that element. The mass number is the SUM of the protons and neutrons in the nucleus, and is always a whole number. I think you have been saying 'atomic mass' but meaning 'mass number'. Take this problem. The information would be better given as: element: chromium ionic charge: +3 atomic number: 24 mass number: 52 Then we can tell you that it will have 24 protons, and 21 electrons, and since the number of neutrons is the difference between the mass number (A) and the atomic number (Z), then A-Z=28. So there are 28 neutrons in THIS part..
