The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element.
The atom that decayed is called the parent.

What term indicates the process in which unstable nuclei releases radiation?
The term is "radioactive decay".
What is a radioactive element's half-life?
The time it takes for a half of the element to decay. In Example: Technetium-99 has a half life of 6 hours. If you begin with a sample of 100g, then after 6 hours you will have 50 grams, at 12 hours you will have 25 grams and so on; however it will NEVER reach 0 (it will remain in exponentially small ammounts because of the asymptote in the graph). This specific exponential decay is shown by the equation y=100(0.5)((1/6)x)
What is the term given to the time it take for one half of a sample of radioactive nuclei to decay?
I believe that term would be 'half-life'
What is an atom's half-life?
The term half-life is one we apply to radioactive materials to talk about how quickly they decay. The half-life is the time it takes for half of a given sample of the unstable substance (whatever it may be) to undergo radioacitve decay. The way it works is quite simple, and though the numbers are statistically derived, they are pretty darn accurate. Let's look more closely.A sample of a radioactive nuclide (radiocarbon or carbon-14 for example) is made up of atoms with unstable nuclei. These nuclei will "fall apart" (decay radioactively) spontaneously, and each one can decay at any moment. What we don't know is when a givennucleus will decay. But if we watch a large number of these nuclei, we can count the decays across a period of time, and then come up with a rate of decay. We convert this into the length of time it takes for half of the given sample to decay. This length of time will be the half-life for that particular radionuclide. Each radionuclide has a unique half-life, as you might expect.A half-life is based on the decay rate of a particular isotope of a given element. It is a natural characteristic of that given radionuclide, and it is the amount of time it takes for a sample of it to decay to the point where half of it is gone and half the original sample remains. Use the links below to related questions to learn a little more.Drugs also have a half-life. Some drugs stay longer in the system, some disapate quickly. If the doctor wants to maintain a level of the drug in the body it maybe necessary to prescribe a dose every several hours or once or twice a day depending on how long the half-life of the drug is.From Wikipedia..The duration of action of a drug is known as its half life. This is the period of time required for the concentration or amount of drug in the body to be reduced by one-half. We usually consider the half life of a drug in relation to the amount of the drug in plasma. A drug's plasma half-life depends on how quickly the drug is eliminated from the plasma.Half life is the time duration in which half of the radioactive element would undergo decay. Suppose just for understanding purpose let us say half life is 3 hours.Say we have 4096 atoms freshNow after 3 hours half of this ie 2048 have got decayedIn the next 3 hours ie totally in 6 hours half of this ie 1024 would get decayed and 1024 would remainNow in the next 3 hours half of this ie 512 would get decayedIn the next 3 hours 256 and then 128, 64, 32, 16, 8 and so onBut in reality there would millions of atoms.
What is the difference between and radioactive and stable isotope?
Radioactive isotopes emit radiation in the form of alpha, beta, positron or gamma rays to become a stable isotope of any given particular element. This is caused by the instability of the nucleus of the atom. The stabilising process in which unstable atoms undergo is known as radioactive decay. Isotopes that are stable do not emit radiation. For example; Carbon-12 is stable and carbon-14 is radioactive.
What term used to describe rate of radioactive isotopes?
Half-life (in units of time).Half-Life is the rate of radioactive decay, measured in time. The half life gives the time it take for half of the radioactive atoms in a system to decay. Fore example, if you have 10 grams of carbon-14, it will take 5730 years for half of it to decay, giving you 5 grams. In another 5730 years, you'll have 2.5 grams left, etc...Isotopes decay at an exponential rate. A half-life is the time that half of the population of an isotope will decay. The measure is a statistical probability and is more accurate when a large population is observed. The term half-life is applied to describe a property of a given isotope (i.e. the half-life of Carbon 14 is 5730).half life
Use the term radioactive decay in a sentence?
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."

What term indicates the process in which unstable nuclide release radiation?
If it is related to Nuclear studies, then the answer would be fusion.
When do the decay series end?
When the element is stable. (apex)
What term indicates the process in which unstable nuclei releases radiation?
The term is "radioactive decay".
Why is Radioactive decay is said to be random?
The underlying truth in radioactive decay is that on an individual basis, no unstable atom will have a predictable time until it will decay. We understand and characterize the decay of radionuclides on the basis of statistical analysis. Only by looking at a large number of atoms of a given isotope of a given element and counting the decay events over time can we quantify the decay rate. The term half-life is used to state (based on the statistics) when half of a given quantity of a substance will have undergone radioactive decay. Note that atoms are incredibly tiny things, and even if we have very tiny quantities of a given radioactive material, we'll have huge numbers of atoms of that material in the sample. The larger the number of atoms of material and the longer we count the decay events, the more accurate our half-life value will be. Having said all that, no one can predict when a given atom of any radionuclide will decay. Each is different, and that is the basis for the random nature of nuclear or radioactive decay.
What is it meant by the term stable isotope?
Stable isotopes do not undergo nuclear decay. Hydrogen has three isotopes, two are stable and the third is unstable. They are ;_ protium; 1 proton , 0 neutrons and 1 electron (Stable) The commonest isotope of hydrogen. deuterium ; 1 proton , 1 neutron and 1 electron (stable). Also known as 'heavy hydrogen - used to make heavy water). tritium ; 1 proton , 2 neutrons, and 1 electron (unstable - undergoes radio-active decay).
A general term for any isotope of any element?
Nuclide
