The half-life of a nuclide is an indicator of its stability; shorter half-lives generally correspond to less stable nuclides that decay more rapidly, while longer half-lives indicate greater stability and slower decay processes. Stable nuclides have half-lives that can extend to billions of years, while unstable ones may have half-lives measured in seconds or minutes. Thus, a nuclide's half-life provides insight into its likelihood of undergoing radioactive decay over time.

Compared to the half life and decay mode of the nuclide 90sr the nuclide 226ra has?
Compared to the half-life and decay mode of the nuclide (^{90}\text{Sr}), the nuclide (^{226}\text{Ra}) has a significantly longer half-life and a different decay mode. (^{90}\text{Sr}) has a half-life of about 28.8 years and primarily decays via beta decay to (^{90}\text{Y}). In contrast, (^{226}\text{Ra}) has a half-life of about 1,600 years and decays primarily through alpha decay to (^{222}\text{Rn}). This means that (^{226}\text{Ra}) is more stable and persists longer in the environment compared to (^{90}\text{Sr}).
What is the half-life of a radioisotope if a 50-g becomes 25 g after 18 years?
18 years. Half-life is defined as the time it takes 50% of the nuclide to decay.
How much of the original sample will be left after one half life has passed?
After one half-life, one half, 0.5, of a radionuclide will remain. After a second half-life, one half of the half, 0.25, will remain, and then after a third, 0.125, and so on. The equation for half-life is ... AT = A0 2(-T/H) ... where A0 is the original activity, AT is the activity after some time T, and H is the half-life in units of T. Keep in mind that the specific half-life only applies to the original nuclide, and that daughter products may well form and have their own half-lives. Also, half-life is relatively constant for each nuclide, unless some chemical situation is present, such as a fully ionized (electron stripped) nuclide, which can inhibit electron initiated decay, such as beta+ and internal conversion.
How is the age of an object that contains a radioactive nuclide estimated?
The age of an object containing a radioactive nuclide is estimated using radiometric dating, which relies on the known half-life of the nuclide. By measuring the ratio of the parent radioactive isotope to its stable daughter product in the sample, scientists can calculate how many half-lives have passed. This information, combined with the half-life duration, allows for the determination of the object's age. Common methods include carbon dating for organic materials and uranium-lead dating for minerals and rocks.
What does the half life tell about a radiosotope?
Its stability. The longer the half-life, the more stable is the isotope.
Which nuclide has a half-life that is less than one minute?
One example of a nuclide with a half-life less than one minute is technetium-95m, which has a half-life of about 61 seconds. This nuclide is commonly used in nuclear medicine for imaging procedures due to its short half-life.
What is the importance of knowing the nucleus half life?
The nuclide half-life tells you what the nuclide is, and if the the decay rate is inconsistet, it can help tell what mix of nulides are presetn in the sample
The time required for half the atoms in a sample of a radioactive nuclide to undergo decay?
The half-life.
What is the amount of time it takes for half of a radioactive sample to decay?
its called the half-life and it is different for each nuclide.

18 years. Half-life is defined as the time it takes 50% of the nuclide to decay.
Which statement is true about half-lives?
A. Different atoms of the same nuclide have different half-lives.B. each radioactive nuclide has its own half-life.C. All radioactive nuclides of an element have the same half-life.D. All radioactive nuclides have the same half-life.

If a sample of radioactive materiel contains 17 daughter nuclide what percent of parent nuclide is present in the sample?
If there are 17 daughter nuclides, then this represents 17 half-lives. Each half-life corresponds to a 50% reduction in the parent nuclide. Therefore, 17 half-lives would result in 1/2^17 (0.0000763) or approximately 0.00763% of the original parent nuclide remaining in the sample.

Its stability. The longer the half-life, the more stable is the isotope.
What is curie half life?
Half-life depends on the particular nuclide involved. You did not specify which nuclide. Please restate the question. Curie is a unit of radioactivity, expressed as 3.7x1010 disintegrations per second. It is not a radionuclide. If you meant curium, you still need to specify which isotope, because curium has several. The longest lived isotope of curium is 96247Cm, with a half-life of 1.56x107 years.
