Several examples are uranium, thorium, radon, actinium, protactinium, plutonium, americium, etc.
Sodium does not exhibit natural radioactivity. However, artificial radioisotopes of sodium can be produced in a laboratory setting through nuclear reactions.
Hematite itself is not radioactive. It is a common iron oxide mineral that does not exhibit radioactive properties.

Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons, resulting in different atomic masses. A neutral element is an atom of that element with equal numbers of protons and electrons, balancing out the charges to be electrically neutral.
If you mean HALF LIFE, that is the length of time it takes a quantity of a radioactive element to lose half its radioactivity.
Radioactivity is the property in which unstable nuclei of an element spontaneously emit radiation.
Yes, dubnium is a synthetic element and its properties are not well-studied due to its high radioactivity and short half-life. It is not known to exhibit luster in its elemental form.
Sodium does not exhibit natural radioactivity. However, artificial radioisotopes of sodium can be produced in a laboratory setting through nuclear reactions.
Yes, polonium was one of the first elements discovered to exhibit radioactivity. It was discovered by Marie Curie and her husband Pierre Curie in 1898, leading to their pioneering research on radioactivity.
Radioactivity is discovered on uranium.
no
Radioactivity
It is a man-made element and, due to its high radioactivity does not exist in nature.
Hematite itself is not radioactive. It is a common iron oxide mineral that does not exhibit radioactive properties.

The process where an element turns to another is radioactive decay, and exposure to radioactivity is dangerous.
You can say that as long as the alpha particle itself is not originating from a radioactive element. If however one is able to isolate the helium nucleus from the elemental atom and then used for bombarding towards the beryllium then it is considered as an example of artificial radioactivity. Or the production of a radioactive element(synthetic element) like Francium can be considered artificial radioactivity.
