Question
Radon gas (Rn) is produced by the alpha (alpha) decay of radium Write the equation for this decay showing the parent nucleus and the decay products. Make sure to write the mass number and the atomic number on each nucleus. Write the number of neutrons and protons that are present in the nucleus of the isotope of Rn. ? #of protons ____ # of neutrons ____ The air in a student's basement apartment contains 2.3 times 10^7 Rn nuclei. The Rn nucleus itself is radio too decays by emitting an alpha particle. The half-life of Rn is 3.8 days. Calculate the number of particle second that are emitted by decaying Rn nuclei in the room. The Radon gas (Rn) nucleus decays by the emission of an alpha (alpha) particle to a Polonium nucleus. Write the equation for this decay showing the parent nucleus and the decay products. Make sure to the mass number and the atomic number on each nucleus. The masses of the Radon, Polonium, and alpha atoms are 22.0175777 u, 218.0089730 u, and 4.002603 respectively. Calculate the change in mass and the disintegration energy.Explanation / Answer
Q21.
Rn or Radon isotopes have 86 protons (since atomic number Z=86),
and radon-222 has 136 neutrons (222-86=136), radon-220 has 134 nuetrons.
