Atoms with a low ionization energy hold tight to their outer valence electrons

No; the phrase given characterizes high rather than low ionization.

Atoms with a low electronegativity like calcium might bond with

an atom with a high electronegativity, like fluorine

Elements that typically attract electrons are what

Halogens.

If a chlorine atom gains or loses a valence electron it becomes a charged particle called an

Ion. Any atom that loses or gains an electron becomes an ion.

When atoms in a covalent bond have a rather high difference in the electronegativities the bond is set to be

A polar covalent bond.

What conditions suggest a bond will be ionic

If the electronegativity difference between the bonding atoms are more than 1.7 according to Pauling's scale, the bond shows a dominant ionic character.

If a chlorine atom were to attract an electron from sodium the chlorine atom would become charged.

positively

Why are the valence electrons found in metallic bonds different from other bonds because of what

Metallic bonds have delocalized electrons.

Atoms like sodium and lithium often lose electrons, which makes them

cations
