I'm surprised it's missed off the spiral/ circluar versions https://webelements.com/periodic_table_image_long.html https://webelements.com/periodic_table_image

  I'm a science teacher, and every time I introduced students to the periodic table I tried to use one of the extended versions. For people just learning atomic structure, that version is much nicer for building an understanding of the connection between atomic structure and the periodic table.

  The "long format (32-column) periodic table" is the one that makes the most sense to me. The ones that put the alkalis (and hydrogen) over on the right don't make sense to me, and putting helium in the same column as beryllium etc. sort of makes sense from the standpoint of electron shells, but completely obscures the chemical properties.
