Question

What is another name for the transition metals? [Question ID = 1500][Question Description = 160_6_PHSC_AUG22_Q60]

• A. Noble gases
• B. Group 3-12 elements
• C. Group 1 elements
• D. Group 18 elements

Hint:

While transition metals are Groups 3-12, the Lanthanides and Actinides at the bottom of the table are called "Inner Transition Metals."

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The modern periodic table is organized into groups (vertical columns) and periods (horizontal rows). Transition metals occupy a specific block in the center of the table.

Step 2: Detailed Explanation:
Transition metals are the elements found in the d-block of the periodic table.
According to the IUPAC nomenclature, these correspond to Groups 3 through 12 (Statement 2).
They are called "transition" metals because they represent a transition in properties between the highly reactive s-block metals (Groups 1 and 2) and the less metallic p-block elements.
They are characterized by having partially filled d-orbitals in their neutral state or in their common oxidation states.
Noble gases (Statement 1) and Group 18 elements (Statement 4) are the same thing—stable, non-reactive gases at the far right.
Group 1 elements (Statement 3) are called Alkali Metals.
Transition metals typically have high melting points, high densities, and show variable oxidation states. Examples include Iron, Copper, and Gold.

Step 3: Final Answer:
Transition metals is the term used to describe the elements in Groups 3 to 12.
