The periodic table of elements is the table that arranges different elements based on their common properties in rows and columns. It helps to organize and classify elements by their atomic number, electron configuration, and chemical properties.
Mendeleev arranged elements in order of atomic mass. He arranged elements in rows and columns that later helped in discovering modern periodic table.
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.
periods are the rows and families are the columns
