Early Attempts
Dobereiner's triads: in a set of three similar elements the middle atomic mass is the average of the other two, for example chlorine, bromine, iodine (35.5, 80, 127). Newlands' law of octaves: the eighth element resembles the first, but the law fails for heavier elements.
Mendeleev's Table
Mendeleev arranged elements by increasing atomic mass in periods (horizontal rows) and groups (vertical columns) of similar properties. It predicted undiscovered elements and corrected some atomic masses. Its defects were a few inversions of mass order, similar elements in different groups and no place for isotopes.
Modern Periodic Law
Moseley showed that atomic number is more fundamental, so the properties of elements are periodic functions of their atomic numbers. The long form has s, p, d and f blocks based on electron configuration.
Atomic size, ionisation energy, electronegativity and metallic character vary regularly along a period and down a group. Along a period, size decreases and non-metallic character increases.
