23. The disintegration of the radioisotope radium-226 produces an isotope of the element radon and alpha radiation. The atomic number of radium. (Ra) is 88 

α-decay process The nuclide Ra(226,88) decays by alpha exission to Radon Rn(222,86). The speed of the emitted α particle is determined experimentally (the curvature if its path in a transverse magnetic field), or evaluated by determinig the related mass defect. It is about 1.52 x 10 7 m/s ( 5% c). 2018-03-29 · Explanation: And mass and charge are (almost conserved) in nucular reactions 226 88 Ra → 222 86 Rn + 4 2H e2+ + 2e− and congratulations, I think this is the first time for a long time that I have had to look up an elemental symbol on the Table.I thought for a moment that radon≡Rd.

Radium-226 is part of the uranium decay series decay chain The series of decays or transformations that radionuclides go through before reaching a stable form. For example, the decay chain that begins with Uranium-238 culminates in Lead-206, after forming intermediates such as Uranium-234, Thorium-230, Radium-226, and Radon-222.
