Explanation:
Detailed explanation-1: -Carbon-12 is considered a reference for all atomic mass calculations. Thus, the mass of any isotope of any element is expressed in terms of the 12C standard of AMU.
Detailed explanation-2: -Hydrogen is taken as the standard reference for measuring the atomic mass unit. No worries! We’ve got your back. Try BYJU’S free classes today!
Detailed explanation-3: -Since the chemical atomic weights of carbon 12 are almost equal to those of the natural mix of oxygen, it was selected as the standard. Since no other nuclide has an identical whole-number mass on this scale except carbon-12. Six protons, six neutrons, and six electrons make up carbon-12.
