Arrange the following transition elements of the first series in increasing order of their densities
(A) Sc
(B) V
(C) Zn
(D) Cu
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A), (B), (C), (D)
Step 1: Recall approximate densities of the elements
Typical densities (in g/cm³) of these elements:
- Sc (Scandium) ≈ 2.99
- V (Vanadium) ≈ 6.11
- Zn (Zinc) ≈ 7.14
- Cu (Copper) ≈ 8.96
These are approximate values from the periodic table.
Step 2: Arrange in increasing order
$\text{Sc (2.99)} < \text{V (6.11)} < \text{Zn (7.14)} < \text{Cu (8.96)}$
