How Many Halflife Are These In A 100-year Span How Many Grams Of The Sample Would Remain At The End Of The 100 Years?
If the substance has a half-life of 10 years, there would be 10 half-lives in a 100-year span. Each half-life reduces the amount by half, so after 100 years, 1/2^10 = 1/1024 grams of the sample would remain.
Is iodine in nuclear bombs?
No. However one of the fission products produced is Iodine-131 and it appears in the fallout. Iodine-131 is a dangerous beta and gamma emitter with a halflife of 8.05 days, it concentrates in the thyroid gland and can selectively kill it or cause cancers in it. Fortunately the halflife is only just over a week, because it then practically disappears in about 5 to 6 weeks. This allows Iodine-131 contaminated food and drink (e.g. fresh milk) to be stored and then safely used when the Iodine-131 has decayed. This also makes it possible to protect the thyroid gland by saturating it with ordinary Iodine (usually as potassium iodide pills) until the Iodine-131 has decayed.
What is the balanced equation for rubidium-87 turns into strontium-87?
this is an example of β radiation, n -> p + e Rb-87 -> Sr-87 + e (rem to write atomic numbers in, Rb is 37 and Sr is 38) The halflife 87Rb is 4,88.1010 years.
What element is used to make nuclear weapons?
Uranium-235Uranium-233Plutonium-239DeuteriumTritiumAs tritium is radioactive with a short halflife (12 years), weapons using it age rapidly possibly becoming unreliable. Therefore it is normally produced from Lithium (in the form of Lithium Deuteride) by fission neutron bombardment just before fusion is initiated.
The halflife of Na24 is 15 hours When there are 1000 atoms of Na24 in a sample a scientist starts a stopwatch The scientist stops the stopwatch at 45 hours there are atoms of Na24 rema?
There will be 125 atoms of Na24 remaining in the sample after 45 hours. This calculation is based on the fact that after 3 half-lives (45 hours/15 hours per half-life), the original 1000 atoms would have reduced by a factor of 2 three times, resulting in 1000/2/2/2 = 125 atoms remaining.
What is the atomic mass of uranium239?
Uranium is a radio active metal element. Atomic mass of it is 239.
