Question

why carbon 12 isotope is taken as standard for measurement of atomic mass?❤️‼️​

Answer 1

Explanation:

Instead of using either Hydrogen, or Oxygen as the standard, the isotope of Carbon with 6 protons and 6 neutrons in its nucleus (Carbon-12) was given a mass of exactly 12. ... So the Atomic Mass of Carbon-12 is defined to be 12 exactly and all other atomic, molecular and formula masses are referred to this standard.”

Answer 2

Answer:

Carbon-12 (12C) is the more abundant of the two stable isotopes of carbon ... Carbon-12 is of particular importance in its use as the standard from nucleus
