The decay of radioactive substances follows a decay chain that will sooner or later result in the appearance of a stable isotope of lead. There is an exception for the atoms of a few substances that have undergone decay by spontaneous fission.
Radioactive elements undergo various types of radioactive decay until a stable atomic nucleus arises as a daughter product. This stable daughter element is lead in most cases. Obviously this can't happen for radioactive isotopes lighter than any of the stable isotopes of lead; those decay into a variety of different elements. For example, carbon-14 decays into nitrogen-14 and hydrogen-3 (tritium) decays into helium-3.

Your question is meaningless. Radium IS a radioactive element, and its power depends on the context. If you mean "is there an element more radioactive than radium" then yes, there are many, e.g. astatine.
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.
Parent and daughter in chemistry refer to radioactive decay, where a radioactive isotope of an element decays into another. For example, carbon-14 will beta-decay into nitrogen-14. The half-life associated with that particular process is about 5,700 years. The "parent" is carbon-14 and the "daughter" is nitrogen-14.
this is because an element is sometimes never radioactive but one may be made just to be radioactive this is because an element is sometimes never radioactive but one may be made just to be radioactive
Einsteinium as a radioactive element has itself a radioactive decay.
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
Uranium and Plutonium
francium, an alkali metal
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
It is radioactive decay.
Actimium, plutonium, radon, radium, thorium, uranium
Whether an ISOTOPE (not element) is naturally radioactive depends not only on the number of protons, but also on the number of neutrons. For EVERY element, there are radioactive isotopes.There has to be a certain relationship between the number of protons and the number of neutrons, but the relationship isn't a simple one.
Germanium is an element that reacts naturally to other substances.
You think probable to lead bricks.
It is the naturally occuring element with the highest atomic number (92). It is also radioactive.
Mendelevium does not occur naturally. It is a synthetic radioactive element. It is almost unquestionably toxic.
As radioactive element is an element that is on the Priodic Table of Elements. A Radioactive Element is usually radioactive.
