The d-block elements of the modern periodic table are also known as:
AThe noble gases
BThe alkali metals
CThe halogen group
DTransition elements
Answer & Solution
Correct answer: D. Transition elements
1. The d-block spans groups 3 to 12 in the main body of the table.
2. These elements are collectively called the transition elements.
3. Alkali metals (group 1) and halogens (group 17) lie outside the d-block.
4. Rule out B: alkali metals are s-block, not d-block.
