This layout obviously won’t fit neatly on any kind of page, but make your own and you immediately notice that the periodic table is another kind of alphabet – it’s the Alphabet of the Universe. The “elements strip” is simply the list of all 118 elements on a single line. Note 2: The position of elements 21 (scandium) and 39 (yttrium) are currently being reviewed by the Union of Physical and Applied Chemistry (IUPAC) task group on “The constitution of Group 3 of the Periodic Table” led by Professor Eric Scerri. This 2017 paper, entitled, “On the true position of hydrogen in the periodic table” by Vladimir Petruševski and Julijana Cvetković provides an excellent summary of the various arguments for the alternative positions for Element Number 1 in the periodic table. Some leave hydrogen floating in the middle and some authors have argued that it belongs above carbon. Others place helium above beryllium on the left side. Note 1: Some teachers place hydrogen above fluorine on the right side of the periodic table. Only twenty-five elements are non-metals and they all ‘live’ on the left side of the periodic table. We also notice that metals ‘live’ on the right side of the periodic table. The long-form periodic table places all the elements in a single table with no breaks, thereby maintaining the expected pattern of increasing atomic number when moving left to right from element 56 (barium) and element 88 (radium).īy shading all the metals grey, we immediately notice that most of the elements are metals. Compare, for example, the Royal Society of Chemistry’s with Wikipedia’s interactive periodic tables.
Some publishers place element 57 (lanthanum) and element 89 (actinium) inside the main table. Unfortunately, this layout can be very confusing for students if the reason for moving the “lanthanides” and “actinides” below the main table is never clearly explained.
This format fills the white space on a standard printed page most efficiently. The medium-long form periodic table is the most common layout you will find in textbooks and on laboratory walls. More information about the periodic table
