How are protons and electrons related
Web20 de mai. de 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. WebSo once again for protons, we look at the atomic number, that's 92. So there must be 92 protons. In a neutral atom, the number of electrons is equal to the number of protons. So there are 92 electrons and then finally, to figure out the number of neutrons, we subtract this number from the mass number. So we just need to do 235 minus 92.
