300

If an element has low electronegativity, a large atomic radius, and low ionization energy it is highly ________?

Reactive

400

As you move down a group on the periodic table, the _______ decreases, and protons have a more difficult time attracting electrons.

Electronegativity

500

_____  increases from left to right on the periodic table as it is more difficult to remove valence electrons.

ionization energy
