Compared to the half life and decay mode of the nuclide 90sr the nuclide 226ra has?
Compared to the half-life and decay mode of the nuclide (^{90}\text{Sr}), the nuclide (^{226}\text{Ra}) has a significantly longer half-life and a different decay mode. (^{90}\text{Sr}) has a half-life of about 28.8 years and primarily decays via beta decay to (^{90}\text{Y}). In contrast, (^{226}\text{Ra}) has a half-life of about 1,600 years and decays primarily through alpha decay to (^{222}\text{Rn}). This means that (^{226}\text{Ra}) is more stable and persists longer in the environment compared to (^{90}\text{Sr}).

What nuclide is formed when 90Sr undergoes?
When 90Sr undergoes beta decay, it forms 90Y (Yttrium-90). In beta decay, a neutron is converted into a proton, and an electron (beta particle) and an antineutrino are emitted.
What is the half-life strontium 90?
Strontium-90 (90Sr) is a radioactive isotope of strontium, with a half life of 28,79 years.
Where is Strontium found on the periodic table?
Strontium occurs naturally in the minerals celestite and strontianite. The 90Sr isotope is present in radioactive fallout and has a half-life of 28.90 years. Due to its extreme reactivity to air, this element occurs naturally only in compounds with other elements, as in the minerals strontianite, celestite, etc. Strontium is isolated as a yellowish metal and is somewhat malleable. Strontium is chiefly employed (as in the nitrate) to color pyrotechnic flames red.
What is the chemical formula for strontium iodide and why?
The chemical formula for strontium iodide is SrI2. This compound is formed by the combination of strontium (Sr) and iodine (I) atoms in a 1:2 ratio. Strontium is a group 2 metal with a +2 oxidation state, while iodine is a halogen with a -1 oxidation state, leading to the formation of a stable ionic compound with a 1:2 ratio of cations to anions.

What is the nuclear decay equation for strontium 90?
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!
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 is the nuclear decay equation for cesium-137?
The equation for the beta decay of 60Co is: 2760Co --> 2860Ni + -10e where the -10e is a negative beta particle or electron.
What other salts and heavy metals can also be stored in bones?
Bones can store various salts and heavy metals, including lead, cadmium, and strontium. These elements can accumulate in bones over time through exposure from the environment or diet. Persistent exposure can lead to health issues such as lead poisoning or impaired bone health.
What is strontium in?

Which element is called after a village in Scotland?
STRONTIUMStrontium (pronounced /ˈstrɒnʃiəm/ STRON-shee-əm, /ˈstrɒntiəm/ STRON-tee-əm, or /ˈstrɒnʃəm/ STRON-shəm) is a chemical element with the symbol Sr and the atomic number 38. An alkaline earth metal, strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when exposed to air. It occurs naturally in the minerals celestine and strontianite. The 90Sr isotope is present in radioactive fallout and has a half-life of 28.90 years. Both strontium and strontianite are named after Strontian, a village in Scotland near which the mineral was first discovered.

What products do you use in nuclear energy?
Usually uranium enriched with the U-235 isotope, in the form of uranium dioxide. This is better than metallic uranium as it can stand higher temperature. Plutonium-239 can also be used if available, this has to be separated from spent uranium fuel by chemical means.
