Choose the correct statement The use of ...

Choose the correct statement The use of `.^(12)C` scale has superseded the older scale of atomic mass based on `.^(16)O` isotope, one important advantage of the former being

A

The atomic masses on `.^(12)C` scale became whole numbers.

B

`.^(12)C` is more abundant in the earth's crust than `.^(16)O`

C

The difference between the physical and chemical atomic masses got narrowed down significantly

D

`.^(12)C` is situated midway between metals and nonmetals in the periodic table

Text Solution

Verified by Experts
