What is the mass of 1 curie of cesium 137?
The mass of 1 curie of cesium-137 is approximately 3.7 grams.
Can cesium 137 be dissolved by chlorine?
Cesium-137 will react with chlorine to form cesium chloride. However it is highly radioactive so must be handled carefully, because of this it is often used to treat cancer patients and sterilize medical equipment and some foods.
When cesium-137 undergoes beta minus decay what new element is formed?
Cs-137 decays to become the metastable element Ba-137m which has a half-life of only 2 minutes 55 and then it eventually becomes Barium-137. The nucleus undergoes a transition in which one of the neutrons becomes a proton which moves it up on the periodic table one place to become Barium-137. During this process is gives off a photon (gamma) with an energy level of approximately 662 keV.
Is Cesium a radioactive element?
Only one naturally occurring isotope of cesium is known, cesium-133 (133Cs) which is not radioactive. A number of artificial radioactive isotopes of cesium are known also. One radioactive isotope of cesium is of special importance, cesium-137. It is produced in nuclear fission reactions. Read more on cesium in the link below.
If 12.5 grams of the original sample of cesium-137 remained after 90.69 years what was the mass of the original sample?
To find the original mass of the cesium-137 sample, you can use the exponential decay formula: final amount = initial amount * (1/2)^(time/half-life). With the information provided, you would have: 12.5 = initial amount * (1/2)^(90.69/30.1). Solving for the initial amount gives you approximately 40 grams.
Why is the solubility of cesium 137 a factor in reducing its half-life?
Physical or chemical properties are unrelated to the half-life of an isotope.
If 1.0 mg of cesium-137 decays over a period of 90 years how many mg of cesium-137 would remain?
Since the half-life of cesium-137 is about 30 years, 3 half-lives would have passed in 90 years. The first half-life would leave .5 mg of cesium-137. The second would leave .25 mg, and the third half-life would leave .175 mg of cesium-137.
What is the symbol for cesium 137?
137Cs55 is the symbol for cesium 137.
What is the mass of 1 curie of cesium 137?
The mass of 1 curie of cesium-137 is approximately 3.7 grams.
How many neutrons are in an atom of cesium 137?
In atomic form (as opposed to being an ion), cesium-137 has 55 electrons, just as all cesium atoms have.
Can cesium 137 be dissolved by chlorine?
Cesium-137 will react with chlorine to form cesium chloride. However it is highly radioactive so must be handled carefully, because of this it is often used to treat cancer patients and sterilize medical equipment and some foods.
Does cesium 137 become cesium 135?
Only if it loses two neutrons
What is the weight of cesium?
Ceasium is a metal element. Atomic mass of it is 133.
What is the Half-life of Cesium-124?
I have heard varying numbers from 33. something seconds to years.
What is the parent radioisotope if a beta decay produces barium-137?
Cesium-137

Does intracavitary radiation use cesium?
Yes, intracavitary radiation can use cesium-137 as a radioactive source. cesium-137 is a common isotope used in brachytherapy for treating certain types of cancers.
