Radium has 88 electrons.
The number of neutrons is different for each isotope:
Number of neutrons = Atomic Mass of an isotope - 88
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 protons, 138 neutrons, and 88 electrons.
Radium 226 has 88 protons, 88 neutrons, and 138 electrons.
Radium typically has 138 neutrons.
There are 88 protons/electrons in radium. There are 138 neutrons.

There are 88 protons/electrons in radium. There are 138 neutrons.
Radon has 86 protons, 86 electrons.Rn-222 isotope has 136 (222 - 86 = 136) neutrons
Radium has two valence electrons.
Radium typically has 138 neutrons. This is derived by subtracting the atomic number (88) from the atomic mass (226) of radium.
Radium has one valence electron.
It is an isotope of the element, radium (Ra), with 88 protons, 88 electrons and 147 neutrons (235 - 88 = 147).
