What is a transition metal?
Click to flip
Transition metals are elements found in the d-block of the periodic table which have partially filled d orbitals.
Click to flip
Where are transition metals located on the periodic table?
Click to flip
Transition metals are located in groups 3 to 12 on the periodic table.
Click to flip
List three common properties of transition metals.
Click to flip
They are typically good conductors of heat and electricity, have high melting points, and are often magnetic.
Click to flip
Why do transition metals have multiple oxidation states?
Click to flip
They have multiple oxidation states due to the ability to lose different numbers of d electrons.
Click to flip
Why are transition metals often used as catalysts?
Click to flip
Transition metals are used as catalysts because they can lend and take electrons easily from other substances, facilitating chemical reactions.
Click to flip
Name two transition metals that are known for their ability to form colorful compounds.
Click to flip
Copper and chromium are known for forming colorful compounds.
Click to flip
What is the electron configuration feature that defines transition metals?
Click to flip
They have an incomplete d subshell in any of their commonly occurring oxidation states.
Click to flip
Which property of transition metals is used in the creation of steel?
Click to flip
The ability to create alloys, particularly with iron, is crucial for steel production.
Click to flip
What is a common use of platinum, a transition metal?
Click to flip
Platinum is commonly used in catalytic converters to reduce vehicle emissions.
Click to flip
Which transition metal is known for its magnetic properties?
Click to flip
Iron is a transition metal known for its strong magnetic properties.
Click to flip
What is the role of transition metals in biological systems?
Click to flip
They play critical roles in biological systems, such as iron in hemoglobin which transports oxygen.
Click to flip
How do transition metals often interact with ligands?
Click to flip
They often form complex ions by coordinating with ligands, which donate electron pairs to the metal.
Click to flip
What is a characteristic of transition metal compounds that affects their color?
Click to flip
The color is often due to d-d electron transitions which are enabled by the presence of unfilled d orbitals.
Click to flip
Why is silver considered a transition metal even though its full d orbital in the elemental state?
Click to flip
Silver is considered a transition metal because it can lose an s electron to form compounds, revealing its d orbital.
Click to flip
Name a transition metal that is often used in coins.
Click to flip
Nickel is often used in coins due to its corrosion resistance and metallic luster.
