Learning: Transition Metals

Each question will teach you something new. You will need to take notes.

Question: True or False: I have my notes out and am ready to take notes on this Quizizz.

• True

• False

Cations are metals and are located to the left of the staircase. All metals have a positive charge because they lose electrons to form ionic bonds. Which of the following is a cation?

• Helium

• Zirconium

• Tellurium

• Fluorine

Anions are on the right side of the staircase, are nonmetals, and will GAIN electrons to form ionic compounds. Which of the following is an anion?

• Lithium

• Aluminum

• Bromine

• Lead

Noble gases have full valence shells, so they will not gain or lose electrons to form bonds. Noble gases are "inert" because they do not react or form compounds. Therefore, they are NOT anions even though they are nonmetals. Which of these is NOT an anion?

• iodine

• oxygen

• argon

• phosphorus

The charge of a cation located in an "A" group is the same as its valence electrons, and always positive. What is the charge of aluminum?

• +1

• +2

• +3

• Cannot be determined

• -3

The charge of an anion will be its valence electrons - 8 and will therefore be negative. What is the charge of oxygen?

• -1

• -2

• +1

• +2

• Cannot be determined

Oxidation numbers (charges) form a pattern for the "A" groups as shown in this picture. All alkaline earth metals have what charge?

• +1

• +2

• +3

• -1

Transition metals are in the "B" groups. Post-Transition metals are located beneath the staircase. These metals always have a positive charge, but the exact value of the charge is unknown. Which of these has a variable (unknown) charge?

• Cesium

• Sulfur

• Neon

• Tin

Exceptions! There are THREE elements in the transition metal area that do not transition. Their charges do NOT change. These are silver (+1), cadmium (+2), and zinc (+2). You have to memorize these exceptions. Which of these has a variable charge?

• silver

• tin

• zinc

• cadmium

Because transition metals have different charges, we use a Roman Numeral to represent WHICH charge the ion has in a given compound. What does a Roman Numeral mean in a compound name?

• It represents the positive charge of the transition metal.

• It represents the negative charge of the anion.

• It represents the negative charge of the transition metal.

• It represents how many cations are in the compound.
