How much of one gram of radium -226 will remain unchanged after four half lives?
1g (1/2)4 = 1/16 g
How old is the specimen if the half-life is 300 years and there is 15 times more daughter product than parent material?
Age = no. of half lives x duration of each half life ratio of Parent nuclei : Daughter Nuclei 1 : 15 total of 16 parts, and for every 16 parts one part is a parent nuclei Mt = Mo x (0.5)^n Mt = amount remaining Mo = Initial amount n = number of 1/2 lives Mt = 1/16 (1/2)^n = 1/16 (1/2)^n = (1/2)^4 n=4 Age = 4 x duration of each half life Age = 4 x 300 Age = 1200 Therefore, the age of the specimen is 1200 years.
35 of students at Charles Walters Middle School live more than 7 miles from school. What fraction of the students lives more than 7 miles from school?
The answer depends on the total number of students at the school. Since this information has not been disclosed, it is not possible to answer the question.
What does number integers mean in math?
There is no such word.An integrator is a person or operation that integrates a function.
After three half-lives what fraction of a radioactive sample will remain?
Approx 1/8 will remain.
What is the percentage of radioactive nuclei left after 3 half-lives have passed?
12.5%
What fraction of a radioactive sample remains after three half-lives?
Not sure what you mean by "had-lives". After 3 half lives, approx 1/8 would remain.
Why After three half-lives what fraction of a radioactive sample remains?
The fraction that remains is 1/8.
Why are the nuclei of elements with atomic numbers greater than 82 naturally radioactive?
Massive nuclei are unable to remain bound aganst the repulsive force of their protons, which all have positive charge. This also occurs with elements #43 (technetium) and #61 (promethium) which because of their particular nuclear geometry are inherently unstable and radioactive, with the only natural isotopes having half-lives of just over 2 years.
What percentage of a radioactive element will remain after seven half lives?
1/27 = 1/128 = 0.78125%
After three half-lives what fraction of a radioactive sample remains?
1/8 of the original amount remains.
How much parent material will be left after five half-lives?
Only 1/32 of the original radioactive material will remain. (½)5 = 1/32
After 6 half-lives What percentage of a radioactive sample remain?
After 6 half lives, the remaining will be (1/2)6 i.e 1/64 th of the initial amount. Hence by percentage it would be 1.5625 %
The range of half- lives of different radioactive elements is form?
From a tiny fraction of a second (10-18 seconds or so) to more than 1015 years.
What fraction of U-238 atoms present at 1 half-life remain after 2 half-lives?
1/2 (50%) of them.
