    A.) This is called by electron shielding - energy level trumps zeff

    b.) Electronegativity conceived as the ability of an atom in a covalent bond should increase with atomic number.

    C.) Increases from left to right as the nulesus and electron cloud gain charge (Nuclei Hold onto Electrons tighter.) Descreases from top to bottom as electrons move further out and becomes more shielded. Noble Gases are left out ecause they don't tend to form bonds.

    D.) Atomic Radius affects the Reacticity by increasing the Halogen elements from top to bottom.
