Question

As we know Atomic mass of an element is compared with one twelfth of mass of carbon 12 Why ? (Give reason Minimum two sentences)​​

Answer 1

Answer:

Some of the mass of the atom gets converted into binding energy, so the mass of the entire nucleus would actually be less than the mass of each individual proton and neutron added together. This is why the mass of carbon-12 is 12 amu, not 12.09.

Answer 2

Hey mate,

Here's your answer.. ☺

• One atomic mass unit is defined as one-twelfth of the mass of one carbon - 12 atom because C-12 is chosen as the standard atom.
• This is because it has the equal number of protons and neutrons (6) and constitutes most of the matter.
• This is because it has the equal number of protons and neutrons (6) and constitutes most of the matter.The most abundant isotope of carbon is Carbon - 12.

Hope it helps. ❤
