Answer 1

Answer:

hope it helps... pls mark me as brainliest...

Step-by-step explanation:

The Periodic Law states that the physical and chemical properties of the elements recur in a systematic and predictable way when the elements are arranged in order of increasing atomic number.

The periodic table arranges the elements by periodic properties, which are recurring trends in physical and chemical characteristics. ... These trends explain the periodicity observed in the elemental properties of atomic radius, ionization energy, electron affinity, and electronegativity.
