Periodic table of the elements

How to use it

1. Filter by group or state to show a family of elements, then select the ones you are teaching.
2. Hide names or symbols to turn the table into a recall exercise; press a cell to reveal it.
3. Quiz yourself on the selection; each mistake comes back once at the end of the round.
4. For class: print the table with the selected symbols missing, or cards for the selected elements, or put the table on the board.

Worked examples

Quick reference

• The atomic number is the number of protons in an atom's nucleus; the table is in order of atomic number.
• Rows are periods (1–7) and columns are groups (1–18), as numbered by IUPAC.
• The lanthanides (57–71) and actinides (89–103) sit in the two rows below the table, with their place in group 3 marked.
• Symbols are written in Latin letters in every language: one capital letter, sometimes followed by a small one.
