Since the atomic number of Sr is less than 90, Sr undergoes beta decay.
Beta decay is when the element decays into another element and a neutron actually breaks apart (sort of) into an electron and proton; the proton attaches to the other element, but the electron stays alone.
Thus:
90------>90 Y+e0-1
38 Sr--->39 Y+e
*there should only be one e, and the 0 and -1 should be in front, just like with the elements, but the format deletes the extra spaces so i put it like that for clarity's sake. sorry!

∙ 13y agoThe equation for the beta decay of 90Sr is: 3890Sr --> 3990Y + -10e
where the -10e is a negative beta particle or electron.

What is the symbol for strontium?
There should be 42 isotopes! because if you count the amount of sr isotopes sr=strontium there is 42 if you count hose all sorry if i am wrong it is just an estimated hypothesis
Why is radioactive Strontium Ninety very dangerous to your health?
Strontium 90 is beta active with a half life of 28 years. It tends to be absorbed in the body's bones and therefore it can give a continued dose for years which can affect the bone marrow. See link to Wikipedia
How long is the City of Ember?
90 minutes (1 hour and 30 minutes.)
What is the LCM of 90 and 45?
45 + 45 = 90 and just 90 a lone = 90 so the LCM is 90
What is the highest common factor of 90 and 180?
The GCF of 60 and 90 is 30.
What is the product of a beta emission from strontium-90?
Yttrium-90 "the slash is important"
What is the y-90 decay equation in which zicronium-90 is produced?
90Y --> 90Zr + e- 90Zr, stable
The half-life of strontium-90 is 28 years How long will it take a 76 mg sample to decay to a mass of 19 mg?
56 years
In the following decay equation 90 39 y is the?
daughter element
What kind of nuclear reaction is seen in 90 39Y-90 40Zr 0 -1e?
Beta Decay (@chickenfingers is correct, thank you)
What is the nuclear decay equation for uranium-238 to strontium-90?
The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.
What would happen if strontium-90 is found in nuclear fallout?
it will likely concentrate in the bones, either affecting the marrow or causing bone cancer.
What is the half-life strontium 90?
Strontium-90 (90Sr) is a radioactive isotope of strontium, with a half life of 28,79 years.
What other isotope besides tellurium-137 is produced by nuclear fission of uranium-235?
Strontium-90 and cesium-137 and a whole lot more.
This equation is an example of what nuclear decay 232 90 Th to 4 2 He plus 228 88 Ra?
Alpha
How is strontium-90 produced?
is strotium-90 a solid liquid or gas
What is it made out of strontium?
Strontium-90 which is a highly dangerous radioactive component of nuclear fallout from above ground testing of nuclear weapons. This spreads throughout the environment to contaminate dairy, beef, pork, basically all products of the soil. Grass to the cow to the milk to the table to your bones and organs, you get the idea. However, stable strontium (non-radioactive) is non-toxic. It seems to be, so far in testing, the most effective substance yet found for the prevention and treatment of osteoporosis as well as other bone conditions.
