When radium-226 decays to form radon-222, the radium nucleus emits a alpha particle.
What else can I help you with?
When radium-226 decays to form radon-222 the radium nucleus emits a?
When Radium-226 decays to form Radon-222, the Radium nucleus emits an alpha particle. The atomic number goes down by 2, and the mass number goes down by 4, matching the atomic number and mass number of the alpha particle.
How did radon get its name?
Radon gets its name from the Latin word "radon" which means "radiation" or "ray." It was named so because radon is a radioactive gas that emits alpha particles as it decays.
What dangerous gas is produced when radium decays?
Radon
When radium emits an alpha particle the resulting nucleus has atomic number?
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
What is the beta decay of radium 226?
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
When a radon 222 nucleus decays what is the other product that forms?
Radon-222 undergoes alpha decay to produce polonium-218as a daughter.
What gas is produced when radium decays?
The extremely dangerous Radon (my favorite element).
How do the properties of radium differ from the properties of the compounds formed by radium?
Radium glows in the dark and is radioactive. When it decays into Radon gas, it emits alpha particles. It is fairly close to its compound radiumchlorite because like radium, it also decays emiting alpha particles. However, radiumchlorite is used to help cure canser. Overal, radium is like its most comon compound but can also have properties not related to its compounds at all.
What new element is formed when radium decays?
The neutrons aren't really relevant, since we don't know what the mass of the radium nucleus was and the element is determined strictly by the number of protons anyway. Radium has an atomic number of 88; losing 4 protons would make the atomic number 84, which is polonium. (This is probably really a two-step process: radium -> radon -> polonium, where each step is an alpha decay.)
When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
What is the beta decay of radium?
226 Ra 88 ---> 225 Ac 89 +W boson W boson ---> e- + neutron
What is the atomic structure of radium 226?
Radium-226 has 88 protons and 138 neutrons in its nucleus. It belongs to the alkaline earth metal group in the periodic table. Radium-226 is a radioactive element that decays into radon-222 through alpha decay.
