The density of radium is 5,5 g/cm3.
The atomic mass of radium is approximately 226 atomic mass units.
Radium typically has 138 neutrons. This is derived by subtracting the atomic number (88) from the atomic mass (226) of radium.
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).
The estimated atomic weight of radium is approximately 226. It is a radioactive element that is part of the alkaline earth metal group on the periodic table.
The atomic number of radium (Ra) is 88.The atomic weight of Ra is 226 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!

When Radium-226 decays to form Radon-222, the Radium nucleus emits an alpha particle. The atomic number goes down by 2, and the mass number goes down by 4, matching the atomic number and mass number of the alpha particle.
An average atom of radium has an atomic number of 88, which means it has 88 protons in its nucleus. It also typically contains 138 neutrons, resulting in its most stable isotope, radium-226. Radium is an alkaline earth metal and is known for its radioactive properties, emitting alpha particles and gamma rays as it decays. Additionally, it has an atomic mass of approximately 226 u (atomic mass units).
The atomic mass of a radium atom is approximately 226. It is a highly radioactive element found in group 2 of the periodic table.
