Due to electron shielding, which occurs when more electrons are introduced at the same energy level as the outermost electron, this is the case.
It is feasible to anticipate an atom’s reactivity, including which ion(s) will form from that element, thanks to the protons, neutrons, and electrons that give an atom its unique features.
Since they are found in the atom’s nucleus, protons and neutrons are referred to as nucleons jointly.
The mass number of the chemical element will be determined in part by the number of protons and neutrons. The quantity of electrons present will depend on the number of protons.
The chemical will be determined by this electron.
