23.1.1 Properties of Transition Metals Flashcards
Transition metals are a unique group of metals in the center of the periodic table distinguished by the fact that they have only partially filled d orbitals. Which of the following correctly lists characteristics of transition metals?
similar sizes; higher densities than other metals; unique magnetic properties; often colored when part of compounds
Look at the chart for the first row of transition metals. Which of the following best explains the variation in oxidation states?
electron configuration
Copper and iron are valuable transition metals that are typically oxidized when mined from the earth. Which statement best compares the recovery of elemental copper and iron?
Reduction of iron is required to convert it to the pure metal, but the reduction of copper is accomplished through the oxidation of sulfur.
What is the principal characteristic of transition metals that distinguishes them from other elements?
Transition metals have partially filled d orbitals in their valence shell.
Which of the following elements is a transition metal?
gold (Au)
When we write the electron configuration for fourth period transition metals, we use the notation “[Ar]” to denote that the transition metal has the same configuration as argon plus some additional electrons. For example, Ti is written as [Ar] 3d24s2. What is the correct electron configuration for argon (Ar)?
1s22s22p63s23p6
Which of the following is not characteristic of transition metals?
Transition metals have localized valence electrons.
Which of the following best explains the reason for the different oxidation states of transition metals?
electron configuration
Which statement best explains why transition metals are easily oxidized?
Transition metals have low electronegativity values.
Copper and iron are much more abundant in nature than other transition metals. Which statement best compares copper and iron?
Copper is easier to reduce than iron. Copper is also 1000 times less abundant than iron.
