What made up all radioactive elements?
After disintegration all radioactive elements are transformed in other elements.
Is radioactive atoms the same as the sun?
No. The sun is made up of a ball of gases, and the only radioactive gas we know of is Radon. Also, most radioactive elements are man-made.
What is made up of 2 or more elements?
what is made up of two or more elements
Is curium dangerous element?
Cerium is very mildly radioactive, to the point of being non radioactive for most practical purposes. Natural cerium is made up of 88.886% stable material, but 11.114% is made up of 142Ce, which has a half life of 50,000,000,000,000,000 years. Like all other elements, there are radioactive synthetic isotopes of cerium.
Can all elements be stable?
All radioactive elements are unstable. Most isotopes of elements in periodic table are radioactive. Overall, most of the elements are unstable but they are present in traces on earth. Most elements on earth are stable.

What are monoisotopic elements?
Mono isotopic elements are stable isotope of an element.From 80 isotopic elements there are 26 radioactive elements discovered up till now.These mono isotopic may or may not be radioactive if they are radioactive they have halve lives.
The halogen family is made up of a group of very active?
elements
Elements after which element are radioactive?
The atoms that are radioactive are those with unstable nuclei. There is no easy way to tell which is which, so the isotope has to be looked up. All elements have at least some radioactive isotopes. There are 36 elements for which all radioactive isotopes are synthetic or fission products, so for practical purposes, there are no radioactive isotopes of them in nature, except where introduced by human activity. They include most of the common elements we find in nature, but not all. There are 44 elements that are found as stable isotopes, but at least traces of radioactive isotopes are found in nature. Among these are hydrogen, carbon, sodium, silicon, chlorine, and potassium, all of which are necessary for life. Radioactive potassium, in particular, is present as 0.012% of all potassium. For another group of elements, including technetium, promethium, and all with atomic numbers of 83 (bismuth) or more, there is no isotope that is stable.
How certain sources of energy are due to the sun?
All except geothermal which is due to the previous star that exploded and made the elements that make up the radioactive elements which coalesced with others to make the Earth and which decay providing heat.
What elements are made up of monecules?
All elements are made up of molecules.
What is made up of 2 or more elements?
what is made up of two or more elements
