A block of the periodic table of elements is a set of adjacent groups. The term appears to have been first used (in French) by Charles Janet. The respective highest-energy electrons in each element in a block belong to the same atomic orbital type. Each block is named after its characteristic orbital; thus, the blocks are:

• s-block
• p-block
• d-block
• f-block
• g-block (hypothetical)
