There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals. Please note that the elements do not show their natural relation towards each other as in the Periodic system. Now, compute the sum of products of number of atoms to the atomic weight: Molar mass (C 12 H 22 O 11 (sucrose)). Then, lookup atomic weights for each element in periodic table: C: 12.0107, H: 1.00794, O: 15.9994. The unity for atomic mass is gram per mol. First, compute the number of each atom in C 12 H 22 O 11 (sucrose): C: 12, H: 22, O: 11. To be balanced, every element in C2H4 + F2 C2H4F2 must have the same number of atoms on each side of the equation. Multiply the number of atoms by the atomic weight of each element found in steps 1 and 2 to get the mass of each element in C6H8F2: Molar Mass (g/mol) C (Carbon) 6 × 12.0107 72.0642. The lightest chemical element is Hydrogen and the heaviest is Hassium. The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning.
