WebRadium occurs in 5 natural isotopes: 223 Ra, 224 Ra, 225 Ra, 226 Ra and 228 Ra. All isotopes are very slightly radioactive and occur only in traces. Radium-223 is composed of 88 protons, 135 neutrons, and 88 electrons. Radium-224 is composed of 88 protons, 136 neutrons, and 88 electrons. WebThe atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 − 53 = 74). Since the iodine is added as a 1− anion, the number of electrons is 54 ...
