The number of neutrons in the nucleus in any atom varies, however, the average is easy to find. The atomic number is the number of both protons and electrons. The Atomic Mass is the number of AMUs (atomic mass units) in the atom. 1 amu is the same as the mass of 1 proton or 1 neutron. the mass of the electrons is negligible. Because of this, subtract the atomic number from the atomic mass and you should have the average number of neutrons.
Radium typically has 138 neutrons.
Radium typically has 138 neutrons. This is derived by subtracting the atomic number (88) from the atomic mass (226) of radium.
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass - 88 The most stable and known isotope of radium, 226Ra, has 138 neutrons.
Radium has 88 electrons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of an isotope - 88
Radium has 138 neutrons.
Radium typically has 138 neutrons.
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.
