The Mass Number
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. The atomic number represents the number of protons in an atom, so adding the atomic number to the number of neutrons will give you the mass number.
Adding the number of protons and neutrons in the nucleus of an atom gives the mass number of the isotope.
protons and neutrons. This is because the atomic mass of an element is calculated by adding the number of protons and neutrons in the nucleus of an atom. The number of protons determines the element's identity, while the number of neutrons affects its stability.
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
The mass number is calculated by adding the number of protons and neutrons together. In this case, the mass number would be 60 (27 protons + 33 neutrons).
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. The atomic number represents the number of protons in an atom, so adding the atomic number to the number of neutrons will give you the mass number.
Adding the number of protons and neutrons in the nucleus of an atom gives the mass number of the isotope.
The mass number of an atom is found by adding the number of protons and neutrons in its nucleus. It is an integer value that represents the total number of nucleons in the atom.

The mass number of ammonia is 17. This is calculated by adding the number of protons and neutrons in the nucleus, which for ammonia (NH3) is 7 protons and 10 neutrons.
The combined number of protons and neutrons is known as the mass number of an atom. It can be used to calculate the atomic mass by adding the total number of protons and neutrons in the nucleus of an atom.
The mass number is calculated by adding the number of protons and neutrons, so for a Chlorine atom with 17 protons and 18 neutrons, the mass number would be 17 (protons) + 18 (neutrons) = 35. The atomic number is simply the number of protons, which in this case is 17.
The mass number is calculated by adding the number of protons and neutrons together. In this case, the mass number would be 60 (27 protons + 33 neutrons).

The symbol for an atom with 17 protons and 18 neutrons is ( \text{Cl} ) (chlorine). The atomic number, which represents the number of protons, is 17, making it chlorine. The mass number, calculated by adding the number of protons and neutrons, is 35 (17 protons + 18 neutrons). Therefore, the complete symbol with the mass number is ( \text{Cl}^{35} ).
All parts of the nucleus, protons and neutrons if any, contribute to the atomic mass. The total number of protons and neutrons in an atom is its isotope mass number.
