Open Ended

What do you know about the transition metals?

Multiple Choice

Which of the following best describes transition metals?

• Metals found in groups 3-12 of the periodic table with multiple oxidation states

• Metals found only in group 1 of the periodic table

• Nonmetals with single oxidation state

• Metals that do not form ions

Open Ended

Explain how the d-shift in electron configuration is related to the bonding behavior of transition metals.

Multiple Choice

Why do transition metals have the ability to choose how many electrons they give away when bonding with other atoms?

• Because they have a fixed number of outer electrons

• Because they can adjust their inner (core) electrons

• Because they always give away the same number of electrons

• Because they do not bond with other atoms

Multiple Choice

Which of the following statements about copper is correct?

• Copper always has a +1 charge when it bonds

• Copper always has a +2 charge when it bonds

• Copper can have either a +1 or +2 charge when it bonds

• Copper never gives away electrons when it bonds

Multiple Select

Select all the correct statements about copper(I) chloride and copper(II) chloride.

• Copper(I) chloride is a white solid

• Copper(II) chloride is a blue solid

• Copper(I) chloride has a melting point of 498°C

• Copper(II) chloride has a +2 charge

Fill in the Blanks

To determine the charge of copper in copper(II) chloride, you should look for the

numeral in the compound's name.

Open Ended

Explain how different charges on chromium ions affect their biological and chemical properties.

Multiple Choice

Why is the charge of an ion important in determining its properties?

• Because it affects the color only

• Because it determines the toxicity and usefulness

• Because it changes the shape of the molecule

• Because it has no effect
