In other words the elements of what we now call a 'period' were listed vertically by mendeleev. Dmitri mendeleev has invented the periodic table which arranges all the chemical elements in a proper way that is in the order of increasing atomic predictions and gaps in this way of arranging elements mean there are gaps in his horizontal rows that are called 'periods'. Many of his earliest publications relate. The periodic table of elements was designed independently about the same time by two different scientists.
