Metallic radii of some transition elements are given below. Which of these elements will have highest density?
| Element | Fe | Co | Ni | Cu |
|---|---|---|---|---|
| Metallic radii/pm | 126 | 125 | 125 | 128 |
A
Fe
B
Ni
C
Co
D
Cu
Answer
Cu
Explanation
Solution
All the four metals have nearly the same metallic radii and hence nearly the same atomic volume. On account of higher atomic mass of copper it has high density amongst given metals.
