Have you ever wondered?

3. What is the difference between

atomic weight and atomic mass?

Carbon-12

Carbon-12 = 99%

Carbon-13 = 1%
Multiply the

atomic mass of Carbon-13

each isotope by = (12  0.99) + (13  0.01)

its percent = 11.88 + 0.13

abundance Atomic weight = 12.01

Electron Measure of how a mass

Neutron acts in a gravitational

Proton field 80
