Question

what is difference between atomic mass and mass number​

Answer 1

Explanation:

The major difference between atomic number and mass number is that the atomic number states the number of protons present in an atom whereas, the mass number indicates the total of the number of protons and the number neutrons present in an atom.

Answer 2

Explanation:

1. THETHE NUMBER OF PROTONS PRESENT INSIDE THE NUCLEUS OF AN ATOM OF AN ELEMENT IS CALLED ATOMIC NUMBER IT IS REPRESENTED BY THE LETTERS Z EACH ELEMENT HAS ITS OWN ATOMIC NUMBER..
2. SINCE AN ATOM IS EQUAL TO THE NUMBER OF PROTON AND ELECTRON THE ATOMIC NUMBER OF AN ELEMENT IS ALSO EQUAL TO THE NUMBER OF ELECTRONS PRESENT IN IT
3. Z= NUMBER OF PROTONS = NUMBER OF ELECTRONS
4. EACH ELEMENT HAS A UNIQUE ADD TO MAKE NUMBER AS NO TO ELEMENT CONTAIN THE SAME NUMBER OF PROTONS ELECTRONS DOES AN ATOMIC NUMBER CAN EASILY BE USED TO DISTINGUISH ONE ELEMENT FROM ANOTHER..

• MASS NUMBER
• THE SUM OF TOTAL NUMBER OF PROTON AND THE NUMBER OF NEUTRONS PRESENT IN THE NUCLEUS OF AN ATOM AND ELEMENT IS CALLED AS MASS NUMBER OF THE ELEMENT IT IS REPRESENTED BY LETTER A MASS NUMBER (A EQUAL NUMBER OF PROTONS + NUMBER OF NEUTRONS EQUAL ATOMIC NUMBER + NUMBER OF NEUTRON
