Metallic and Nonmetallic CharacterThe most metallic elements are in the bottom left hand corner of the periodic table.

The most nonmetallic elements are in the top right hand corner of the periodic table.

Reactivity Trends

Metal reactivity increases down a group because as nuclear shielding increases and the nucleus' hold on the valence electron weakens, therefore it is easier to remove valence electrons.

Nonmetal reactivity decreases down a group because the nucleus' ability to gain more valence electrons weakens due to more nuclear shielding.

Metal Reactivity

For Metals: the most reactive metals are those that can lose their valence electrons the most easily.

Francium has the lowest electronegativity and the largest atomic radius therefore it is very easy to remove it's valence electron.

Francium is the most reactive metal.

Nonmetal Reactivity

Fluorine has the highest electronegativity and the smallest atomic radius therefore it gains valence electrons the most easily.

The most reactive nonmetals are those that can most easily gain valence electrons.

Fluorine is the most reactive nonmetal.

Why don't the noble gases have electronegativity values and the largest first ionization energies?
