Aluminum: Al: 13 - Covalenz radius: 28.0855: Silicon: Si: 14 - Ionization energy: 30. click on any elements name for further information on chemical properties, environmental data or health effects. The division sign (/) implies “per,” and “1” is implied in the denominator. Chemical elements listed by atomic mass The elements of the periodic table sorted by atomic mass. For example, the molar mass of Ba(OH) 2 requires the sum of 1 mass of Ba, 2 masses of O, and 2 masses of H: The molar mass of Ba(OH)2 requires the sum of 1 mass of Ba, 2 masses of O, and 2 masses of H: 1 Ba molar mass:īecause molar mass is defined as the mass for 1 mol of a substance, we can refer to molar mass as grams per mole (g/mol).
In formulas with polyatomic ions in parentheses, the subscript outside the parentheses is applied to every atom inside the parentheses.
