![]() ![]() If you are working with a single isotope or known mixture of isotopes, you should always use that value for your calculation and not the average value for the planet. Compared to a black and white periodic table, being color coded by element groups makes a big difference to a person who just begins to learn about chemical elements. While these ranges might be more accurate, they are basically useless for chemistry calculations, where you need just one number! The atomic mass values on this table are the latest single values agreed upon by the IUPAC or predicted by scientists. This printable color coded periodic table makes it easier to identify trends and elements which share similar chemical and physical properties. Electrons s p d 2 8 18 32 18 1 f +3 +1 196.967 Gold Au 79 11 IB Group (IUPAC) Group (CAS) Atomic Number Symbol Name Atomic. ![]() Their newer tables include a range of values, to better reflect the uneven distribution of isotopes in the Earth's crust.

It includes nihonium, moscovium, tennessine, and oganesson and has the revised atomic masses (in the few cases where changes were made).īe advised: The IUPAC has moved away from single atomic mass values for elements. Download & Print Free Periodic Table Worksheets Here These periodic table elements printable pages are sized for standard letter printer paper dimensions 8.5 x 11 inches. While the 2015 editions of the periodic table remain popular, it's nice to have the latest accurate information for all 118 elements! This is the 2019 edition of the printable periodic table.
