Do Elements become radioactive when the strong nuclear force overcomes the repulsive electrostatic force?
No. Radioactive elements are normally a result of the atom actually being an isotope of that element. An isotope is an atom of an element that has a different amount of neutrons than the norm. For example, the normal amount of neutrons in a Carbon atom is six, but Carbon-14 has eight, and Carbon-16 has ten. These isotopes are normally radioactive.
Scientists used radioactive decay to measure what?
amount if living organism that is expected to radioactive isotope.
When an atom undergoes radioactive decay when does it become a completely different element?
An atom of a given isotope will undergo radioactive decay whenever it feels like it. No joke. The nucleus of a radioactive isotope is unstable. Always. But that atom has no predictable moment of instability leading immediately to the decay event. We use something called a half life to estimate how long it will take for half a given quantity of an isotope to undergo radioactive decay until half the original amount is left, but this is a statistically calculated period. No one knows how long it will take a given atom of a radioactive isotope to decay, except that those with very short half lives will pretty much disappear relatively quickly.
Measures the amount of particle vibration?
Amplitude measures the amount of particle vibration.
Which factor controls the amount of radiation emitted from the xray tube?
mA
What is the relationship between radioactive isotope and radioactive dating?
In radiometric dating, the amount of a certain radioactive isotope in an object is compared with a reference amount. This ratio can then be used to calculate how long this isotope has been decaying in the object since its formation. For example, if you find that the amount of radioactive isotope left is one half of the reference amount, then the amount of time since the formation of the object would be equal to that radioactive isotope's half-life.
What is the half life of an isotope?
The half-life of a radioactive isotope is the amount of time it takes for one-half of the radioactive isotope to decay. The half-life of a specific radioactive isotope is constant; it is unaffected by conditions and is independent of the initial amount of that isotope.
What is half life of a isotope?
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.
Why must radioactive decay must be constant in order for radioactive dating to be accurate?
Amount of certain radioactive isotope in an object is compared with a reference amount. this ratio can then be used amount.
Why must radioactive decay must be constant in order for radiometric dating to be accurate?

What is it called when it takes an element half the amount of time for a radioactive isotope to decay?
Half-life
Can the half life of a radioactive isotope decrease as the isotope decays?
No, the half-life of a radioactive isotope does not decrease as the isotope decays. That half-life remains constant. It's the amount of the substance that decreases as the isotope decays.
Where could radioactive waste be stored in?
This depends on the amount, specific activity, chemical form, type of emitted radiations.
Determine the amount of time it takes for three fourths of a radioactive sample of an isotope of bromine to decay the half-life of the isotope is 16.5 hours?
About 33 hours
Why was the radioactive atom was discovered?
They were discovered because the amount of energy they emit was measurable, but the method and manner in which it is emitted was inexplicable at the time.
How is radioactive decay used to determine the absolute age a rocks?
The basic idea is to measure the amount of the radioactive isotope, and of one or more of its decay products. The older the rock, the larger the percentage of the original isotope that decayed - so the ratio between the original isotope and the decay product changes over time.
What are the different types of dating?
By far the most common is radioactive dating which involves checking the amount of a given radioactive isotope in a given sample is left over (and calculating from the half-life [the time it takes for a radioactive element/isotope to decay to half the original amount]). Another one would likely be tree-ring dating which only determines the age of trees by how many rings it has.
