Question

what is mean by atomic mass number ? Explain how the atomic number and mass number of carbon are 6 and 12 respectively.​

Answer 1

Explanation:

Atomic number of an element refers to the number of electrons or protons present in that element. It is denoted by Z. ... Carbon has 6 protons, 6 electrons and 6 neutrons. So the atomic number is 6 as the number of protons is 6. The mass number is 12 as the sum of protons and neutrons is 12.

Answer 2

Answer:

Atomic mass of an element is defined as the total mass of the nucleus .

Atomic mass number[A] is defined as the sum of protons and neutrons present in the atom.

Atomic number [Z] is the total number of electrons (OR) total number of protons in a neutral atom of the elment .

Difference :

Atomic number is the total number of electrons (OR) total number of protons in a neutral atom of the elment  but Atomic mass number is the sum of

protons and neutrons present in the atom.

Note: no of neutrons = atomic mass number - atomic number
