When the nuclide strontium-90 undergoes beta decay the name of the product nuclide is?
Strontium- 90 decays to yttrium-90, which in turn decays to stable zirconium. The isotopes of strontium and yttrium emit beta particles as they decay.
What is the symbol for the element produced when strontium-90 undergoes beta decay?
Strontium-90 Decay Chain As 90Sr decays, it forms 90Y or Yttrium-90 which has a half life of 64 hours. The 90Y decay results into a stable substance called Zirconium (Zr).
What happens when a nuclide undergoes beta decay?
Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e – +.
What isotope is produced when strontium-90 undergoes two successive beta decays?
First, it happens to be a cascade decay. Strontium-90 decays into unstable Ytrium-90 that later decays into stable zirconium-90. The Ytrium lifetime is much shorter than that of Strontium-90 (respectively 64 hours and 29-years radioactive half-lives). Moreover, the two successive decays are almost 100% beta..
When the nuclide strontium 90 decays to yttrium-90 what kind of decay does strontium 90 undergo?
β−
) is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. It undergoes β− decay into yttrium-90, with a decay energy of 0.546 MeV.
When strontium 90 undergoes a beta decay The products of the reaction would be?
Strontium-90 decays to yttrium-90 by emitting a beta particle, and yttrium-90 decays by emitting a more energetic beta particle with a half-life of 64 hours to zirconium-90.
When the nuclide strontium-90 decays to yttrium-90 what kind of decay does strontium-90 undergo?
What is the nuclide symbol for strontium?
Sr
Strontium is a chemical element with symbol Sr and atomic number 38.
What happens when an element undergoes beta decay?
Beta decay occurs when an unstable nucleus emits a beta particle and energy. A beta particle is either an electron or a positron. A: In beta-minus decay an atom gains a proton, and it beta-plus decay it loses a proton. In each case, the atom becomes a different element because it has a different number of protons.
How does strontium-90 decay?
Strontium-90 decays to yttrium-90 by emitting a beta particle, and yttrium-90 decays by emitting a more energetic beta particle with a half-life of 64 hours to zirconium-90. The main health concerns for strontium-90 are related to the energetic beta particle from yttrium-90. produced by nuclear fission.
What is the decay constant of strontium-90?

What kind of decay does Strontium 90 undergo?
Here’s what I got. Strontium-90, 90Sr, undergoes beta minus decay, so your goal here will be to use what you know about the emission of a beta particle to figure out the resulting nuclide. A beta particle, aa0 −1β, is simply a high-speed electron.
What happens to a neutron during beta minus decay?
When a radioactive nuclide undergoes beta minus decay, a neutron located inside its nucleus is being converted into a proton. At the same time, a aa0 −1β particle and an electron antineutriono, ¯νe, are being emitted.
What is a beta particle in a nuclide?
A beta particle, aa0 −1β, is simply a high-speed electron. When a radioactive nuclide undergoes beta minus decay, a neutron located inside its nucleus is being converted into a proton. At the same time, a aa0 −1β particle and an electron antineutriono, ¯νe, are being emitted.
How does the atomic number of strontium change?
However, its atomic number, which tells you how many protons are present inside the nuclues, will change. More specifically, the atomic number will increase by 1. A quick look in the periodic table will show that strontium has an atomic number of 38. Another quick look in the periodic table will reveal that the daughter nuclide is yttrium-90, 90Y.
