This family is called, after IUPAC nomenclature -- actinoids.
After disintegration all radioactive elements are transformed in other elements.
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.
Mineral salts are compounds made up of ions derived from minerals, and they are not a family of elements themselves. Elements are the simplest substances made up of only one type of atom, such as oxygen, sodium, or iron. Mineral salts are formed when certain elements combine with each other to create specific compounds, like sodium chloride (table salt) or calcium carbonate.
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.
A compound is made up of two or more different elements that are chemically bonded together. Each compound has a fixed ratio of elements and distinct properties different from its individual elements.
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.
After disintegration all radioactive elements are transformed in other elements.

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.
Radioactive elements are naturally occurring elements with unstable atomic nuclei that emit radiation as they decay. Common examples include uranium, thorium, and radium. These elements can be found in minerals, rocks, and soil.
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.
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 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.
Over 99.999% of argon is not radioactive. A trace of radioactive argon-39 can be found in nature, but it is not significant. Synthetic radioactive isotopes of argon exist, as they do for all elements.
matter is made up of material which is made up of elements which is made up of atoms
Cerium is an element that is found in the Earth's crust. Cerium is in the Lanthanide family which is made up of rare earth metals.
