Why do scientists analyze radioactive decay? How do scientists use radioactive isotopes? Why are gamma rays more dangerous than radio waves? How does ionizing radiation affect molecules? Why is beta radiation more penetrating than alpha radiation?
Atoms are also not like rabbits, they don’t care how many they are. There isn’t a maximuman age or minimum before gettingpopulation based adjustment to the constant random decay rate. So why is the half life constant, it’s because atoms of a particular type are all identical....
The basic concept of radioactive decay kinetics is that every single nucleus has the same probability of decaying at any single given time, regardless of the physical-chemical surroundings (it does not know anything about the other atoms). This of course means that they...
Why is radioactive decay measured in half-lives? Why is graphene used in electronics? Why does the strong nuclear force become repulsive? What type of isotope would be used in the generation of power within a nuclear power plant, and how do its characteristics allow it to be used in the ...
Radioactive decay is entirely random and it is impossible to predict when a specific atom will decay. However, at any point in time, each radioactive atom in a sample has the same probability of decaying. Therefore, the number of decay events (or reduction in the numb...
These particles are produced in various processes, including nuclear fusion in the sun, radioactive decay in nuclear reactors and Earth’s crust, and experiments inparticle accelerators. As they move, neutrinos can switch between three types, or “flavors,” in a process that continues to intrigue...
What makes radioactive atoms get old so quickly and decay? Explain why hydrogen and helium atoms have the necessary speed to escape but why other elements, such as oxygen and nitrogen, do not. Fill in the blanks below. Options: inverse, faster, square, slower Why do photons have different...
aFigure 3.8 In radioactive decay, if parent isotope "X" decays to daughter isotope "Y," then, after a time known as one "half-life," 50% of the parent will have decayed to form an equal number of atoms of the daughter. If the half-life of radioactive parent X is known, the age...
It is what is emitted from the nucleus under alpha decay, giving off what was first classified as alpha radiation by Rutherford at the end of the 19th century (very late 1800's). In 1932 the neutron was discovered. Only then did it become clear that the nuclei of at...
There is a general trend that atoms with even atomic numbers have more stable isotopes than those with odd atomic numbers. If you flip through a book that lists all of the stable isotopes for each atom (a good one to do this with is Elmsley's "The Elements"), you will notice that ...
