6Dmitri [blank_start]Mendeleev[blank_end] realised that when you arrange elements by their atomic [blank_start]mass[blank_end], similar [blank_start]properties[blank_end] appear regularly. He arranged the elements in a [blank_start]table[blank_end] so that elements with the same properties could be found in a column or [blank_start]group[blank_end]. To make them fit, he had to leave [blank_start]gaps[blank_end], which allowed him to [blank_start]predict[blank_end] the properties of elements which had not yet been discovered.
