It really applies to radioactive isotopes, not elements. An element may have different isotopes, some of which are radioactive, some not.


The half-life is the time it takes for half of a sample to decay - for the atoms to convert to some other type of atom.

none, uranium itself is unstable, there are no stable elements after bismuth; and even some researchers suggest that bismuth is an unstable radioactive element with a halflife approaching twice the age of the universe.


All radioactive nuclides of an element have the same half life?

Is it true that the half-life of a radioactive isotope decreases as the isotopes decay?

no, halflife is a constant for each isotope's decay process.


How would you describe the isotopes of hydrogen?

Hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H). Protium is the most abundant and consists of one proton and one electron. Deuterium contains one proton, one neutron, and one electron. Tritium has one proton, two neutrons, and one electron.

A radioactive element is one that discharges radiation. Uranium is a radioactive element. A radioactive element is very dangerous if you don't have protective clothing. You should never go near a radioactive element.


What characterizes a radioactive element?

A radioactive element is characterized by having unstable atomic nuclei that decay and emit radiation in the form of alpha particles, beta particles, or gamma rays. This decay process results in the transformation of the element into a different element or isotope.
