Answer : Option 2) Nonmetallic properties and ionization energy


Explanation : It is observed that the nonmetallic properties and the ionization energy when the elements in period 3 on the periodic table are considered in order from left to right.


Various changes are observed when we move from left to right in period 3 in the modern periodic table like the atomic number and charge on the nucleus increases , number of valence electrons increases , atomic radius decreases , first ionization energy increases , electro negativity increases except in Ar, elements found on the left are metals and elements on the right are non-metals, so non metallic character increases.
