All nuclear fuels contain radioactive elements.
ernest Rutherford _______________________________________________________________ Radioactive decay was actually discovered in 1896 by Henri Bacquerel. Ernest Rutherford discovered the formula of radioactive decay (Such as the falk-life, differences between alpha and beta decay and even how the elements become new elements after the decay), but he did not discover the radioactive decay himself.
it is used by scientist to to calculate a rock's age

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.
Some synthetic elements are naturally radioactive due to their unstable atomic structures. For example, elements beyond uranium on the periodic table are typically artificially produced and tend to be radioactive. These elements can emit radiation as they undergo radioactive decay.
Am (Americium) and U (Uranium) both radio active. Ne (Neon) is an inert/noble gas. K (Potassium - latin ;Kalium) is not radioactive.
No, trace elements are not necessarily radioactive. A link to a list of elements that have no natural radioactive isotopes is at a related question, below.
Radioactive elements make up a small fraction of all naturally occurring elements in Earth's crust. Most elements are stable and non-radioactive. However, even though they are a minority, radioactive elements play important roles in various scientific, medical, and industrial applications.
After disintegration all radioactive elements are transformed in other elements.
Not all of the transition elements are radioactive. Many of them are, and some of them have common radioactive isotopes, but some of them have no naturally occurring radioactive isotopes. Please note that all elements have synthetic radioactive isotopes, at least.
Radioactive elements
Radioactive elements exist in all groups of the periodic table.
Elements with no stable isotopes are called radioactive elements. These elements spontaneously undergo radioactive decay, which leads to the formation of stable isotopes over time.
Radioactive elements exist in all groups of the periodic table.
Yes, but only if it is radioactive. Radioactive elements change into different elements through radioactive decay.
The family of radioactive elements is called the Actinides. This group includes elements such as uranium, thorium, and plutonium, which are known for their radioactive properties.
