The time used for dealing with nuclear decay is called a half life.
Decay of a radioactive atom is something that happens by change, and the atoms of one isotope may be more or less prone to decay than the atoms of another. The way we normally express the rate of decay is to speak of the amount of time it takes for half of the atoms in a sample to decay, which is the same as the time during which any one atom of the sample has a 50% chance of decaying.

When an isotope is it is called radioactive?
Some isotopes are radioactive, some are not.
What word means unstable elements that decay?
The word Radioactive usually denotes a substance containing unstable atomic nuclei.
A substance that is dissolved in liquid is a what?
The dissolved substance is a called a solute.
What are elements with no stable isotopes called?
Radioactive.
What family is made up of radioactive elements?
This family is called, after IUPAC nomenclature -- actinoids.
What the meaning of radioactive?
Any substance which is emitting ionizing particles is radioactive. An example is the metal called Plutonium.
Why is the radiation from a radioactive substance sometimes called nuclear radiation?
Because it is produced by reactions happening inside the nucleus.
A device in which droplets of alcohol condenses around a radioactive substance causing it to leave a trail is called?
It's called a cloud chamber :)
What happens to radioactive materials if you do not use them?
That depends on the radioactive material. But whether you use it or not, the radioactive material will decay into other elements over the course of time. The time it takes for half of the material to decay into something else is called the "half-life". The more radioactive the substance is, the faster it decays. The half-life of a radioactive element can be measured from fractions of a second to billions of years.
What do we call the time it takes for half of a radioactive sample to decay?
The time it takes for half of a sample to decay is called the "half-life" of the corresponding material.
What is the activity of a radioactive substance?
any one or a combination of radioactive substances that gives off photons that are usually considered harmful to humans and other life forms
What are radioactive debris of uranium called?
Radioactive wastes
When an isotope is it is called radioactive?
Some isotopes are radioactive, some are not.
What is ratioactive dating called?
Radiocarbon Dating. It measures the levels of carbon 12, a radioactive substance in everything, and based on how much is left scientists can determine how old something is.
What are the melting and boiling points of ionic?
I don't believe there is a substance called "ionic" If you are asking about "ionium", this is a radioactive isotope of thorium and has a melting point of 1750ºC, and boils at 4790ºC.
True or false unstable atom that decomposes and emits energy is called retroactive?
No, it's called "radioactive." "Retroactive" is something that's active in regards to the past.
When radioactive isotopes break down into other elements the process is called?
radioactive decay
