It is a soft silvery-white alkali metalUnder standard conditions it is the least dense metal and the least dense solid elementLike all alkali metals lithium is highly reactive and flammable and must be stored in vacuum inert atmosphere or inert liquid such as. The upper right side shows the number of electrons in a neutral atom.

The notation of an isotope occurs by adding a subscipt and superscript to the left side of an element such as 238 92U uranium isotope.
. An ion of an atom is one in which the number of protons and electrons is not the same. Lithium L has an atomic number of 3 and an atomic mass of 6941 indicating that many lithium atoms on Earth have more than the 3 neutrons in their nucleus. Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nucleiThe fission process often produces gamma photons and releases a very large amount of energy even by the energetic standards of radioactive decay.
Nuclear fission of heavy elements was discovered on Monday 19 December 1938 by German chemist Otto Hahn and his. The isotope is defined by the number of neutrons in an atom which might be equal to the number of protonsor not. Remember a neutral atom contains the same number of protons and electrons.
As stated above it is these outermost electrons that determine the chemical properties of an atom. In the progression thus far three atomshydrogen lithium and sodiumhave one electron in the outermost shell. The next atom after neon sodium has 11 electrons so that one electron goes into the next highest shell.
An isotope is a variant of an element in which it has an equal number or protons but a varied number of neutrons. Stone is a chemical element with the symbol Li and atomic number 3.
