What is an atom or bonded group of atoms that has a positive or negative charge?

• ion

• atom

• metal

• nonmetal

What is the term of an atom that will lose electron(s) and have a positive change?

• cation

• anion

• electronegativity

• ionic radius

The Halogen group has an oxidation number of -1. Why?

• The Halogen group will gain one electron, therefore have an oxidation number of -1.

• The Halogen group will lose one electron, therefore have an oxidation number of -1.

• The Halogen group will lose seven electrons, therefore have an oxidation number of -1.

What is the trend for atomic radius (radii)?

• It increases left to right on the Periodic Table and decreases down a group.

• It decreases left to right on the Periodic Table and increases down a group.

• It increases left to right on the Periodic Table and increases down a group.

• It decreases right to left on the Periodic Table and decreases down a group.
