Chemotherapy is when radiation is used to kill cancer cells while sparing healthy tissue cells, also doctors sometimes inject patients with a nuclear tracer to show problematic areas that need to be checked out, and Nuclear power plants use nuclear energy to create a large amount of energy from just a small amount of Uranium. These are just some of the ways nuclear radiation is used to help us.
The periodic table contains groups and periods that include the elements. For group 1 metal lithium is least likely to lose an electron.
<h3>What are group 1 metals?</h3>
Group 1 metals are the alkali metals that include, Li, Na, K, Rb, and Cs. They show the property exhibited by the metals. The chemical trends of group 1 show that cesium loses an electron more easily than the other elements.
When going down the group the tendency to lose electrons increases as the atomic radius increases. The electron gets far away from the nucleus making it easy to get removed.
Therefore, lithium being the first element of the group has the smallest radii and is least likely to lose an electron.
