A Radium atom has an atomic number of 88, which means it has 88 protons.
The atomic mass of Radium-226 is 226. In a neutral atom of Radium, the number of protons and electrons are equal. Therefore, the number of neutrons in a Radium-226 atom can be calculated as follows:
Number of neutrons = Atomic mass - Atomic number
Number of neutrons = 226 - 88
Number of neutrons = 138
Therefore, an atom of 226Ra has 88 protons and 138 neutrons.
