Did you know?
WebThe atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus.For ordinary nuclei, this is equal to the proton number (n p) or the number of protons found in the nucleus of every atom of that element. The atomic number can be used to uniquely identify ordinary chemical elements.In an … WebAug 2, 2024 · For all atoms with no charge, the number of electrons is equal to the number of protons. number of electrons = 30. The mass number, 65, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons = 65 − 30 = 35. Exercise 4.8.3.
WebNow, because the atom has 53 electrons, it must also have 53 protons, and to find the number of neutrons we subtract this from the mass number. # n = A – # p = 127 – 53 = 74 neutrons.
