Protons and neutronsCottingham formulaThe Cottingham formula expresses the electromagnetic part of the mass of a particle in terms of the virtual Compton scattering amplitude. At large photon momenta, this amplitude is dominated by short distance singularities associated with operators of spin 0 and ...
Consider the neutron, the proton, and the electron. Which has the largest relative mass? Do protons and neutrons have equal masses? What are their differences? Show how to calculate the mass of a proton, neutron, and electron in kilograms using this data: (Particle, M...
All elements in the periodic table are made of subatomic particles. These are protons, neutrons and electrons. The protons and neutrons are found in the centre of the atom, which makes up the atomic nucleus.Answer and Explanation: Become a member and unlock all Study Answers Try it risk-...

(a)(i)Accept for the relative mass of electron[1] All relative charges are correct[1] All relative masses are correct(ii) The mass of an atom is concentrated in the nucleus of an atom. The electrons are of negligible mass.The nucleus is positively charged(due to the protons), and the...
Explanation of Solution Given,1939X Atomic number,Z =19 Mass number,A =39 The atomic number of the element is equal to the number of protons. The mass number is equal to the sum of the number of protons and neutrons. A = p+n ...
Atoms, the basic building blocks of matter, are made of three basic components: protons, neutrons and electrons. The protons and neutrons cluster together to form the nucleus, the central part of the atom, and the electrons orbit about the nucleus. Protons and electrons both carry an ...
(d) No change by doubling mass of electrons however by reducing mass of neutron to half total atomic mass becomes 6 + 3 instead of 6 + 6. Thus it is reduced by 25 %.
An atom consists of a centrally located nucleus and three types of subatomic particles known as electrons, protons, and neutrons. Answer and Explanation: The correct answer is (b) Protons and neutrons. The protons and neutrons are ...
