This program determines the molecular mass of a substance. Enter the molecular formula of the substance. It will calculate the total mass along with the elemental composition and mass of each element in the compound. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.

Mr. Mendeleev found elements known as element X and element Y, he found that element X and element Y are one of the transition element and non-metallic respectively in periodic Table. Identify Element X and Element Y to their groups from Periodic Table. Using the information from Table 1
Visit BYJUS to learn more about it. The term 'elements' (stoicheia) was first used by the Greek philosopher Plato in about 360 BCE in his dialogue Timaeus, which includes a discussion of the composition of inorganic and organic bodies and is a speculative treatise on chemistry. Plato believed the elements introduced a century earlier by Empedocles were composed of small polyhedral forms: tetrahedron (fire), octahedron (air), icosahedron (water), and cube (earth).

Valency of elements is the property that appears when one atom of an element combines with atoms of other elements. In general, the valence of a valence is equal to the number of electrons that each atom gains and loses when it is combined, that is, the number of electrons that gain and lose when the element can reach a stable structure, which is often determined by the electron arrangement of
