For 226Ra, the most common radium, it had 138 neutron. Other isotope scuch as 223, 224, 228Ra will have number of neutron of the stated molecularmass minus its' atomic number.
The 220 is the atomic MASS, which is the number of protons plus the number of neutrons. 88 is the atomic NUMBER, which is the number of protons only. The "Ra' is the abbreviation for radium, one of the first-detected radioactive elements.
Radon has 86 protons, 86 electrons.Rn-222 isotope has 136 (222 - 86 = 136) neutrons
106 neutrons
Nitrogen has 7 neutrons.
Silicon has 14 neutrons.
