The periodic table was arranged by Mendeleev in the increasing order of atomic numbers. The arrangement sees to it that the elements belonging to the same column has similar properties and the rows are arranged in increasing number of valence electrons. The answer here is true.

Answer: The statement is true.

Explanation:

The statement, currently the periodic table is arranged by increasing atomic number and a clear pattern of properties is true.

According to the current period table, atoms are arranged in increasing atomic number from left to right in every period. Also, chemical properties of an element depend on the number of valence electrons.

Therefore, elements in a group represent similar chemical properties as they have same number of valence electrons.
