Radium has several isotopes, but the most common one is radium-226. This isotope has an atomic number of 88, indicating it has 88 protons. Since the mass number of radium-226 is 226, it contains a total of 226 nucleons, which includes both protons and neutrons. Therefore, radium-226 has 138 neutrons (226 - 88 = 138).
An atom of radium has a nucleus containing 226 particles, which includes 88 protons and 138 neutrons. The number of protons determines the element's identity, while the total number of protons and neutrons gives the mass number of the isotope. Therefore, the nucleus of a radium atom specifically has 226 nucleons.
Beryllium-9 has 9 nucleons.
Radium has 88 protons.
There are 88 protons in a radium atom.
