teacher Will deliver lecture on Periodic table The periodic table is an arrangement of all the elements known to man in accordance with their increasing atomic number and recurring chemical properties. They are assorted in a tabular arrangement wherein a row is a period and a column is a group. Elements are arranged from left to right and top to bottom in the order of their increasing atomic numbers.

Mendeleev’s periodic table Dimitri Mendeleev, widely referred as the father of the periodic table put forth the first iteration of the periodic table similar to the one we use now. Mendeleev’s periodic law is different from the modern periodic table Modern periodic table The modern periodic table, the one we use now, is a new and improved version of certain models put forth by scientists in the 19th and 20th century.
