According to Mendeleev's periodic table, elements are composed in 8 upright columns that express the groups and 12 enlisting rows that state the periods. From left to right in one row, elements are composed based on mass number. In one group, elements from top to down,  is composed based on resemblance of the chemical and physical properties resemblance. Mendeleev table also called Short periodic table.
