The group number is an identifier used to describe the column of the standard periodic table in which the element appears.Groups 1-2 termed s-block elements.Groups 1-2 (except hydrogen) and 13-18 are termed main group elements.Groups 3-12 are termed d-block elements....

When Dmitri Mendeleev drew up the periodic table, he grouped elements of similar properties. Based on the number of electrons, a scientist can determine which group to place an element into.This pattern is called a period(or row) on the periodic table. ...
The standard table provides the necessary basics. There are also other methods for displaying the chemical elements for more details or different perspectives.Standard periodic table Group’ 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Period 1 1 H 2 He 2 3 Li 4 Be 5 B ...
Periodic table is the arrangement of all the known chemical elements by their atomic number and electronic configurations. There are seven periods and sixteen groups present in a periodic table. Elements with similar properties are found in the same group of the periodic table....
