Answer 1

Similar properties recur periodically when elements are arranged according to increasing atomic number."

Answer 2

Answer:

• The ‘fundamental properties of an element’ in that the “modern periodic law” is based on their atomic numbers.

• “The ‘modern periodic law’ states that the “physical and chemical properties” of elements are in the “periodic function” of the respective atomic numbers.

• In the modern periodic table, arrangement was produced in a very strange manner by researchers.
• It keeps all elements in the same vertical column under each other with comparable electronic configuration.
• Groups are these columns that are vertical. On the other side, the horizontal rows are the periods.
