Aradioisotope forms a stable isotope after it undergoes radioactive decay. which is the best conclusion to draw from this statement? it undergoes alpha decay. it undergoes beta decay. it does not participate in a decay series. it does not have a long half-life.

Answer : The correct option is "It does not participate in a decay series."

Explanation :

We have been given that the radioactive element forms a stable isotope after undergoing a radioactive decay.

Here the element becomes stable after emitting any one of the radiations. It is not emitting a series of radiations

Decay series is a process in which an element undergoes a series of radioactive decays in a definite sequence. Each nucleus formed after the decay behaves as a parent nucleus which further undergoes a decay till a stable nucleus is formed.

Example : Decay series of U-238

This element undergoes 14 radioactive decays and finally becomes U-208.

All the remaining options are not correct because we cannot draw any conclusions about the type of decay ( alpha or beta) or the half life from the given information.

The only conclusion that can be drawn is - It does not participate in a decay series.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
