What are Radioactive Elements in Periodic Table?
Some elements are not stable in nature due to the excessive charge concentrated at the nucleus, and because all elements want to be stable in nature, these elements undergo radioactive decay in order to be stable nuclei. These unstable elements are known as radioactive elements. Thus, we can say that the elements that undergo radioactive decay are called radioactive elements.
In stable atoms, the neutron-proton ratio( ratio of neutron to the proton in the nucleus ) is typically close to 1:1 for small nuclei elements(Z<20). However, in unstable or radioactive isotopes, this ratio may be significantly different, which can affect their stability and decay behaviour. This ratio normally rises as Z(Atomic number) rises, reaching 1.587 for Uranium-238. There are a few exceptions to the above rule, such as 1H(Protium) and 3He(Helion), which both have more protons than neutrons and are still stable.
Radioactive Elements in Periodic Table
Radioactive Elements are the elements that emit radioactive waves like alpha waves, beta waves, and gamma waves. The Process is called Radioactivity. They are found throughout the Earth’s crust and have important applications in various fields, including medicines, energy production, etc. The radioactive elements are unstable because of the presence of excess nuclear charge inside their atomic nucleus. These atomic nuclei undergo radioactive decay to form stable nuclei. The elements that undergo radioactive decay are called radioactive elements.
