214^82 Pb express answer as a nuclear equation
The nuclear equation for the decay of Pb-214 can be expressed as:
214Pb -> 210Po + 4He
How long will it take for the radiation level of strontium-85 to drop to half of its original level?
Express your answer as an integer.
The time required for a radioactive substance to reach half of its original level is determined by its half-life. The half-life of strontium-85 is approximately 64.8 days.
To find the time it will take for the radiation level of strontium-85 to drop to half of its original level, we can use the formula:
time = half-life * number of half-lives
In this case, we want to find the number of half-lives it takes for the radiation level to drop by half, so we can rearrange the formula:
number of half-lives = time / half-life
Using the given half-life of strontium-85 (64.8 days), we can plug it into the formula:
number of half-lives = time / 64.8
Since we are looking for the time it takes for the radiation level to drop to half, we can set the value of "number of half-lives" to 1. This gives us:
1 = time / 64.8
Multiplying both sides by 64.8 gives us:
64.8 = time
Therefore, it will take approximately 64.8 days for the radiation level of strontium-85 to drop to half of its original level.
To express the answer as a nuclear equation, we need to identify the element and its corresponding atomic number and atomic mass.
The given number, 214^82 Pb, represents an isotope of lead (Pb). The superscript 214 represents the atomic mass, and the subscript 82 represents the atomic number.
A nuclear equation typically represents the process by which one element transforms into another by undergoing nuclear decay or transmutation. However, since no such process is mentioned in the given number, we cannot provide a specific nuclear equation for 214^82 Pb.
If you have any additional information or context regarding nuclear reactions or transformations involving lead (Pb), please provide that so we can provide a more accurate response.
