18 grams are one fourth of the original sample mass of 72 grams. Accordingly, the half life is 6.2/4 = 1.55 days.
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
Caebon-14 is a radioactive isotope and can decay.
This is because only one isotope decay.
friends are like seashells you collect on the way
The lightest "element" that can undergo radioactive decay is the isotope hydrogen-3, which undergoes beta decay. The lightest element with no radioactively stable isotopes is technetium, and its isotopes have different modes of decay.
The characteristic time for the decay of a radioactive isotope is known as its half-life. This is the time it takes for half of the radioactive atoms in a sample to decay.
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.
its called Half-Time...
The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called the half-life of the radioactive element. It is a characteristic property of each radioactive isotope and can vary greatly among different elements.
Relative decay is the process of determining the age of a sample by comparing the amount of a radioactive isotope it contains to the amount of its decay products. By measuring the ratio of remaining isotope to decay product, scientists can estimate the age of the sample based on the known decay rate of the isotope.
The stable isotope produced by radioactive decay is called a daughter isotope.
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
The rate of decay (activity) of a radioactive isotope is proportional to the number of atoms of the isotope present.
Iodine-131 has a half-life of about 8 days.
It tells what fraction of a radioactive sample remains after a certain length of time.
