Ionic bonding #2

What are monatomic ions?

• Cations consisting of only one type of atom.

• Ions consisting of only one type of atom.

• Anions consisting of only one type of atom.

• Atoms consisting of only one type of ion.

What are polyatomic ions?

• Tightly bounded groups of atoms that behave as a unit and carry a charge.

• Tightly bounded groups of anions that behave as a unit and carry a charge.

• Tightly bounded groups of cations that behave as a unit and carry a charge.

• Tightly bounded group of atoms that behave as a unit but don't carry a charge.

What are valence electrons?

• An electron found in the outer energy level

• An electron found closest to the nucleus

• Any electron

• They don't exist

If I gain electrons I become

• Positive because I've added to my atom
• negative because I've added electrons
• same because i'm balanced
• equal because now I have electrons

If my charge becomes 2+ what does that say about me?

• I am stealing 2 electrons
• I am losing 2 electrons
• I am in period 2
• I have an atomic # of 2

When metals bond with non-metals they form what type of bonds

• covalent
• ionic
• cooperative
• lewis

How do the following two elements bond together?

• Cr₂O₃
• CrO₃

How do the following two elements bond together?
Al³⁺  O^2-         

• AlO
• Al₂O₃
• Al₃O₆
• Al₃O₂

When a nonmetal gains electrons, it becomes this type of ion.

• Anion
• Cation

An ion with a negative charge is a/an

• anion
• cation
