There are several isotopes of francium. Starting with 87220Fr, and going on up to 87232Fr, beta- decay is present in one form or another. Below 87220Fr, we start to see beta+ decay. Mixed in with all of this, we see alpha decay from time to time.
Beta-
A neutron is converted into a proton, increasing the atomic number by 1, and keeping the Atomic Mass number the same. If the parent were 87222Fr, for example, the daughter would be 88222Ra. (Radium) Resulting emissions would include beta particles in the form of electrons and electron antineutrinos, as well as gamma and x-ray from time to time.
Beta+
A proton is converted into a neutron, decreasing the atomic number by 1, and keeping the atomic mass number the same. If the parent were 87212Fr, for example, the daughter would be 86212Rn. (Radon). Resulting emissions would include beta particles in the form of positrons and electron neutrinos, as well as gamma and x-ray from time to time.
Alpha
A helium nucleus, 24He2+, is ejected, reducing the atomic number by 2, and reducing the atomic mass number by 4. If the parent were 87212Fr, for example, the daughter would be 85208At. (Astatine) Resulting emissions would be the helium nucleus as described above, as well as gamma and x-ray from time to time.
Note that I chose 87212Fr deliberately, because it does have two decay sequences, both alpha, and beta+.

∙ 13y agoFrancium has ca. 40 isotopes and isomers; the most stable isotope is francium 223 with a half life of 21,8 minutes. The decay is: 223Fr--------Beta-------223Ra.
Or, 87Fr223 -----> 88Ra223 + e- (beta particle).

93/41 Nb
Are beta emission and beta decay the same?
There is a difference between beta emitters and beta particles. In situations where an atomic nucleus exhibits nuclear instability due to too many neutrons for the number of protons or vice versa, that nucleus may undergo beta decay. It the decay event occurs, that atom is considered a beta emitter. The emitted particle is the beta particle. That's the difference. (There are two different beta particles, so check the articles on beta decay to get the scoop.)
What was the reactant that underwent beta decay if 14 7 N was the product?
7N14 is the product of beta- decay of 6C14. Remember, beta- decay involves changing a neutron into a proton, with the emission of an electron and an electron antineutrino. The W- boson is an intermediate product of the changing of a down quark to an up quark that is represented by the change of a neutron into a proton, which then decays into the electron and electron antineutrino pair.. In a nutshell, with beta- decay, atomic number goes up by one, and atomic mass number stays the same.
What is the name of the product nuclide when bismuth-214 undergoes beta decay?
Bismuth-214 produces Polonium-214 by beta- decay. It also produces Thallium-210 by alpha decay, though at a much smaller percentage.
What would be the product of the beta decay of bismuth?
The beta decay product of francium-223 is radium-223.
What is the product of the beta decay of bismuth?
It depends on which isotope of bismuth we are talking about. Most isotopes less than bismuth-209 that decay by beta do so via beta+, and they decay to lead, while most isotopes greater than bismuth-209 that decay by beta do so via beta-, and they decay to polonium.There are some isotopes that decay by other mechanisms, such as alpha, but the question asked only about beta.
Who made francium?
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
What origin is francium?
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
What is francium's most abundant isotope?
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).
What is the nuclear decay for francium?
Francium-223 decay to radium-223; each isotope have another type of decay.
What is beta decay of thorium 234?
Protactinium 234 is a decay product of thorium 234; the nuclear reaction is: 23490Th-----------beta rays-------------23491Pa
What are the possible products of the alpha decay of uranium-238?
The only possible product of the alpha decay of 92238U is 90234Th.
What is the nuclear equation for beta decay of cesium-137?
The number 87 when referred to francium is that element's atomic number. The most common isotope of francium is 223, which has a half-life of 22 minutes and decays by beta-negative emission into radium-223.
What is carbon-14 decay product?
Nitrogen-14, by way of beta decay.
What is the daughter product of uranium 238 by beta and gamma emission?
The decay product of uranium 238 by alpha disintegration (not beta or gamma) is thorium 234.
What is the other product in a beta decay of zirconium-93?
93/41 Nb
