Question

Please explain everything about radioactivity in terms of perodic table and also how to know which element has a higher radioactivity

Answer 1

Answer:

Explanation:

Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in the case of internal conversion. A material containing unstable nuclei is considered radioactive. Certain highly excited short-lived nuclear states can decay through neutron emission, or more rarely

Answer 2

Answer:

Radioactivity is a measure of the rate an atomic nucleus decomposes into pieces that are more stable. It's somewhat complicated, trying to determine relative radioactivity because there can be many unstable steps in the decay process before an element finally breaks into stable pieces. All of the elements from element 84 on up are extremely radioactive. These elements have no stable isotopes.All of the naturally occuring radioactive elements are concentrated between atomic numbers 84 and 118 on the periodic table, though Tc and Pm are an exception. Also note that there is a break between 110 and 118 on the table, which are suspected radioactive elements that have yet to be discovered. 29 radioactive elements have been identified by scientists to date:

Technetium (TC)- Transition metal

Promethium (Pm)- Rare earth metal

Polonium (Po)- Metalliod

Astatine (At)- Halogen
