Atomic Properties and Ionic Compounds Quiz

Atomic radius - distance from the center of an atom's nuclei to its outermost _______.

Atomic Radius _______ as you move down a group.

Atomic Radius _______ as you move from left to right.

Ionization energy - the amount of energy needed to remove an electron from the outermost _______ of an atom.

Ionization Energy _______ as you move down a group.

Ionization energy tends to increase as you move from left to right across a period. Why? Electrons are harder to remove from smaller atoms because they are closer to the nucleus which has _______.

Electronegativity - the measure of an atom’s _______ for electrons in a chemical bond.

Electronegativity _______ as you move down a Group. Why? Shared electrons are farther from the nucleus in larger atoms.

Electronegativity increases as you move from left to right across a _______. Why? Shared electrons are closer to the nucleus in smaller atoms.

Which has the higher ionization energy?
