Francium-223 decay to radium-223; each isotope have another type of decay.
Actinium-227 decay to francium-223.
227Ac----- alpha decay---- 223Fr
All nuclear decay is spontaneous.
That depends on the nuclear decay type. For gamma decay, the identity does NOT change, but for alpha and beta, it does.
Natural chromium is stable and does not decay/
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
Because it is an element francium cannot decompose. However, it does undergo nuclear decay, which is chemical terms, is different from decomposition.
1. As a natural element francium exist in infinitesimal concentrations in uranium ores (as a progeny of 235U in the decay chain). 2. Francium can be also obtained by nuclear reactions: 197Au + 18O----------210Fr + 5 n
Actinium-227 decay to francium-223.
Francium is very radioactive and very difficult to obtain; heating of francium due to the decay leads to instantaneous vaporization of francium.
Francium has approx. 40 isotopes and nuclear isomers.
what are the forms of nuclear decay
Francium can be detected only by nuclear spectrometry.
Francium has no stable isotopes. That means it doesn't really have a "most abundant" isotope; they're all pretty much nonexistent. There are trace amounts of 223Fr in uranium minerals, because it's a decay product of 227Ac (which is itself a decay product in the decay chain of uranium).
nuclear decay, such as alpha decay or beta decay.
francium is found in thorium and uranium ores in the earth's crust obtained by the decay of actinium
