The elements are given in order of their atomic numbers. The different periods are indicated by gaps after the inert gases. A curious relation, pointed out by Rydberg, is that the atomic numbers of all the inert gases are given by taking the series 2 (P + 2^ + 22 + 3^ + 3^ + 4^ + ) and stoppmg the summation at any term. This gives the numbers used by Langmuir (p. 95). The atomic weights given are t...")
