Why was carbon-12 selected as the standard element for atomic mass?
Can you tell me why carbon-12 was selected as the standard element for atomic mass?
Certainly. Carbon-12 was selected as a standard because it is a stable and abundant isotope, meaning that it does not decay over time and can be found in large quantities in nature. It also has a whole number mass, which makes it easy to use as a reference point.
