Printable periodic table

Which table to print

Names and atomic weights is the table for chemistry class: each box gives the element’s atomic number, symbol, name and standard atomic weight. Names, no weights prints the symbols and names larger, for younger students learning them. Numbers only, to fill in keeps the boxes and the atomic numbers, for the symbols and names to be written in, and To fill in, then the answer key adds the full table as a second page. On Tabloid or A3 paper the full table prints large enough for a classroom wall. On A5 or Half Letter the boxes are too small for the names and weights to be read, so those papers print each element’s number and symbol only.

Reading the table

Each row is a period and each column a group, numbered 1 to 18 across the top, and the elements in a group behave alike: group 1, apart from hydrogen, holds the alkali metals, group 17 the halogens and group 18 the noble gases. The two rows at the foot, the lanthanides and the actinides, belong in group 3 of periods 6 and 7 and are printed below so the table fits the page. An element with no standard atomic weight, such as technetium or plutonium, is radioactive; the number in brackets is the mass number of its longest-lived isotope. American and IUPAC spelling differ only in aluminum and cesium (aluminium and caesium) and in lanthanides and actinides, which IUPAC calls lanthanoids and actinoids. The ready Letter and Tabloid files use the American spelling and the A4 and A3 files IUPAC’s; the Spelling choice sets either on any paper.
