Is the quantity of a radioactive isotope ever equal to exactly zero?

Yes. There are isotopes of elements that are simply not found anywhere in the universe (and even if they did exist momentarily, their lifetime is so short that in the next moment they would have decayed into a different more stable isotope).

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.
In a time equal to two half-lives of a radioactive isotope would you expect all of that isotope to have decayed?
No. In two half-lives, a radioactive isotope will decay to one quarter of its original mass. In one half-life, one half of the mass decays. In the next half-life, one half of the remaining mass decays, and so on and so forth. At each half-life point, you would see 0.5, 0.25, 0.125, 0.0625, etc. remaining. The logarithmic equation is... AT = A0 2(-T/H)
What is produce by changes in nucleus of atoms?
NUCLEUS.Atomic energy is produced from changes within nucleus of an atom.
The half-life of a certain radioactive isotope is 12 hours If you start out with 10 g of the isotope after 1 day there will be?
If you take one day equal to 24 hours, then 1 day constitutes 2 Half lives. Mass of isotope left after 12 hours=10/2=5g Mass of isotope left after 2 half lives or 1 day=5/2=2.5g.
What is the number of neutron is equal to?
The number of neutrons of an isotope is the difference between the mass number of the isotope and the number of protons (equal to atomic number).
What distinguishes an isotope from a regular element?
Isotopes are different forms of an element that have the same number of protons but different numbers of neutrons in their nuclei, resulting in different atomic weights. This difference in atomic weight among isotopes is what distinguishes them from a regular element.
When quantity supplied and quantity demanded are equal the market is in?
Equilibrium.
What physical quantity measured in bar?
The bar is a non-SI unit of pressure, defined by the IUPAC as exactly equal to 100,000 Pa. It is about equal to the atmospheric pressure on Earth at sea level.
The average annual precipitation worldwide must equal the quantity of water?
The average annual precipitation worldwide does not directly equal the quantity of water. Precipitation is the amount of water that falls as rain or snow in a certain area, while the quantity of water includes all water sources such as oceans, rivers, lakes, and underground aquifers. Precipitation contributes to the global water cycle by replenishing freshwater sources through runoff and infiltration.
What is unique about an equilibrium price?
quantity demanded and quantity supplied are equal
Equilibrium is when the quantity demanded is no longer equal to the quantity supplied?
false
What is equilibrium -Gradpoint?
The point at which quantity demanded and quantity supplied are equal
