MCQ
Mendeleev corrected the atomic weight of :
- ✓$\ce{Be}$
- B$\ce{N}$
- C$\ce{O}$
- D$\ce{Cl}$
✓
Answer
Correct option: A.
$\ce{Be}$
Mendeleev's periodic table helped in correcting the atomic masses of some of the elements, based on their positions in the periodic table.
For example, the atomic mass of beryllium was corrected from $13.5$ to $9.0$. Atomic masses of indium, gold and platinum were also corrected.
