The total number of transition elements are?
- A
38
- B
32
- C
58
- D
28
The total number of transition elements is 58. This includes all the d-block elements across the four periods where d-block elements are found (scanning from Scandium (Sc) to Zinc (Zn) in the first series, Yttrium (Y) to Cadmium (Cd) in the second series, and so on). The other options are incorrect because:
Option A (38) includes more elements than just the transition metals, as it counts all d-block elements.
Option B (32) refers only to the transition metals in the first three periods and does not include additional transition metals in the other series.
Option D (28) is also incorrect as it only counts part of the transition elements, neglecting others in higher periods.
Thus, option C is the only accurate count of transition elements.
This option represents the total number of d-block elements, but it includes some elements that are not classified as transition metals.
This number refers to the transition metals found in the first three series of the d-block, but does not account for all transition elements.
This is the correct answer as it accurately represents the total number of transition elements, including all d-block elements across all periods.
This number is incorrect as it mistakenly counts only the first two series of transition elements, missing several others.
