Question

The system of atomic mass units is based on:

a. Assigning C-12 as weighing exactly 12 u & comparing other elements to it.
b. Measuring the true mass of each subatomic particle.
c. Comparing the differences in protons and electrons.
d. Viewing how atoms are affected by electromagnetic fields.

Answer 1

The system of atomic mass units is based on assigning C-12 as weighing exactly 12 u and comparing other elements to it. An atomic mass unit (u) is defined as a mass equal to one twelfth the mass of an atom of carbon-12.

Step-by-step explanation:

The system of atomic mass units is based on assigning C-12 as weighing exactly 12 u and comparing other elements to it. An atomic mass unit (u) is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of an atom is affected by the interactions of particles within the nucleus.
