HELP PLEASE

Why is the r.a.m. value used?
A. A single atom cannot be isolated, so only the average size of a group of atoms can be measured.
B. The r.a.m. value is used to determine how many isotopes an element has.
C. Atoms are too small for their masses to be measured directly.
D. None of these

Respuesta :

I would say it is A because it can be a group of atoms. idk

The r.a.m. value is used to determine how many isotopes an element has. Hence, option B is correct.

What is r.a.m?

The relative atomic mass of an element is a weighted average of the masses of the atoms of the isotopes.

The r.a.m. value is used to determine how many isotopes an element has.

Hence, option B is correct.
