How many protons neutrons and electrons are in radium 222?
Web26 jun. 2024 · For example, atomic number of radium is 88 and mass number is 226. Hence, number of neutrons can be calculated as follows. Mass number = no. of protons + no. of neutrons. 226 = 88 + no. of neutrons. No. of neutrons = 226 - 88. = 138. Thus, we can conclude that there are 88 protons present in radium-226 nuclide.
