88
Radium has 88 protons, 138 neutrons, and 88 electrons.
Radium 226 has 88 protons, 88 neutrons, and 138 electrons.
Radon has 86 protons, 86 electrons.Rn-222 isotope has 136 (222 - 86 = 136) neutrons
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.
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).
Radium has 88 protons and 138 neutrons.
Radium has 88 protons, 138 neutrons, and 88 electrons.
Radium 226 has 88 protons, 88 neutrons, and 138 electrons.
All isotopes of radium have the same number of protons; the number of neutrons is different.
The number of protons of an atom is given by its atomic number. Checking the periodic table, we see that the atom with 88 protons is radium. The isotope of radium with 138 neutrons would thus be 226Ra.
