It's a semantic thing - by definition, if something gives out radiation, then it is radioactive. If an element gives off radiation, then it is a 'radioactive' element. If it does not give out radiation, then it is not 'radioactive'.

Is radioactive radiation an element compound homogeneous mixture or heterogeneous mixture?
Hydrogen is an element.
Which element is Atomic number- 112?
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
How can an atom of one element change to an atom of another element?
By losing protons. Atomic number determines what kind of element it is. ---------------------------- This can only happen if the nucleus changes its number of protons because the nucleus is unstable and undergoes radioactive decay. As it changes it will emit some form of radiation
Was polonium the first source of radioactivity?
All isotopes of polonium (all 25 of them) are radioactive. Only traces of a single isotope exist in nature.
Is fermium toxic?
Fermium is a radioactive element; the chemical toxicity is not determined - fermium was obtained only in quantities of milligrams.
Is radioactive radiation an element compound homogeneous mixture or heterogeneous mixture?
Hydrogen is an element.
Do all atoms give out radiation?
Any excited atomic nucleus can radiate energy, but we generally only see radioactive atoms emitting radiation.
Can one element change into a different element?
Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.
An element that gives off nuclear radiation what?
Sounds to me like radiation from a radioactive isotope. The breaking down part would be the half-life. But the isotope won't completely break down. Only until it reaches a stable form. Such as, radium-226 decays finally to lead-206. During the process it emits charged Alpha particles.
Over time what will happend to the radioactive atom?
They experience radioactive decay. They emit radiation, changing the state of their nucleus, usually by the loss of protons and neutrons. However, this process is completely random; it can only be predicted as a half-life, or the amount of time it takes half of a certain material to decay. This does not predict when an individual atom will decay, it only predicts when approximately half of the material will have decayed.
What is the only way to change one element into a different element?
through radioactive decay
Is Cs a radioactive element?
No, it has only one stable isotope.
How can an atoms of one element change into an atom of a different element?
By losing protons. Atomic number determines what kind of element it is. ---------------------------- This can only happen if the nucleus changes its number of protons because the nucleus is unstable and undergoes radioactive decay. As it changes it will emit some form of radiation
Why can radioactive isotopes be followed through a chemical reaction?
They emit radiation that can be detected with various radiation measurement tools. Usually the isotopes will be in only one of the products of the chemical reaction, making it radioactive and the others nonradioactive.
Which element is Atomic number- 112?
The element with an atomic number of 112 is called Copernicium. It is a synthetic, radioactive element that can only occur in a laboratory.
What is unknown radioactive elements?
A radioactive element is the element which radiates continuously giving alpha, beta, and gamma rays. The elements having atomic no. more than 82 are mostly considered as radioactive elements. These elements emit radiations by themselves even if if they are not get touched. They are discovered by Maria Curie and Pierre Curie in 1907
