Periodic Table Element Tiles

Each element has its own tile with key information in print and braille. The name, symbol, atomic number and relative atomic mass are included, along with a diagram of the valence electrons for the element. The top right-hand corner is cut off to help with orientation of the tile.
So far in this set we have hydrogen, helium, lithium, boron, carbon, oxygen, sodium, aluminium, silicon, phosphorus, chlorine, calcium, chromium, iron and copper. More elements can be added.
The data is from the Royal Society of Chemistry: https://www.rsc.org/periodic-table
Print braille on the vertical face then glue in to the base
