Ionization Energy of Chemical Elements - Periodic Table
Lithium is a chemical element with atomic nuer 3 which means there are 3 protons and 3 electrons in the atomic structure.The chemical syol for Lithium is Li. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and is stored in mineral oil.
Difference Between Calcium Carbonate & Elemental Calcium
The elements on the periodic table can occur in nature in one of two ways: as free elements, or in compounds. A compound is a chemical coination of the atoms of one element with those of another element, or elements. Elemental calcium is pure calcium, while calcium carbonate is an example of a compound of calcium and other elements.
