The Atomic Mass.
The total amount of protons and neutrons in an atom is its mass number.
mass number = protons + nuetrons
mass number = protons + nuetrons
The total mass of the protons and neutrons in an atom is called the atomic mass or mass number. It is often represented by the symbol A.
Carbon 12 has 6 protons and 6 neutrons. The amount of neutrons is exactly the same as the amount of protons.
no there are different elements, and you can check a periodic table for more information.
The sum is called mass number.
It is about neutrons and protons. The total of neutrons and protons.
Mass number is about the neutrons and protons. The total of neutrons and protons.
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.
If the atomic number of an atom is 6 it means that the atom has 6 protons, the mass number on the other hand is the total amount of protons and neutrons in the atom. ( Remember- the amount of protons equals the amount of electrons). So for example if you wanted to find out the amount of neutrons in an atom, you would subtract the atomic number from the atomic mass for the answer. (Whole-protons=neutrons)
Sulfur has 16 electrons, protons and neutrons.
