When radon-222 undergoes alpha decay What other product is formed?
When radon-222 undergoes alpha decay, it becomes polonium-218. Radon loses two protons, so the atomic number becomes 84.
What does radon-222 beta decay into?
Polonium-218 and lead-214 are decay products of radon-222. The final elemen lead-206, is stable (non-radioactive) and its formation ends the series.
What is the product of the alpha decay of radon 220?
During alpha decay, the radionuclide atom produces an alpha particle (42He 2 4 H e ). This produces a daughter nuclide with a lower mass number and atomic number. Consider the alpha decay of Rn-220 (atomic number 86) producing Po-216.
How long does it take for half the radon 220 nuclei to decay?
Radon decays with a half-life of 3.8 days, emitting ionizing radiation in the form of α-particles (helium nuclei).
What is the half-life of RN 222?
Rn-222 has a short half-life (3.8 days) and decays into a series of solid particulate products, known as radon progeny or radon daughters, all of which have even shorter half-lives (∼30 min or less).
How does the daughter product of Radon-222 decay?
Step 1: radon-222 decays by alpha emission. b. Step 2: the daughter product in part a decays by alpha emission and is in a high energy state. c. Step 3: the high energy daughter product in part b decays by beta and gamma emissions and is in a high energy state. d.
Are there balanced nuclear equations for the decay of radon?
The inhalation of radon-222 and its decay to form other isotopes poses a health hazard. Write balanced nuclear equations for the decay of radon-222 to lead-206 in eight steps.
When does an atom decay by alpha emission?
Alpha emission is when an atom loses the equivalent of a helium-4 nucleus, which is the loss of two protons and two neutrons. This nuclear decay… See full answer below.
