The total amount of protons and neutrons in an atom is its mass number.
Protons and neutrons are contained within the nucleus of an atom. The nucleus is located at the center of the atom and it is where most of the atom's mass is concentrated. Electrons, which are negatively charged particles, orbit around the nucleus in electron shells.
Number of protons + Number of neutrons = Mass number(number of nucleons)
The total number of protons and neutrons in an atom is given by the atomic mass number, which is the sum of the number of protons (atomic number) and the number of neutrons in the nucleus of the atom.
The atomic mass of an atom is the sum of the number of protons and neutrons in its nucleus. Therefore, if an atom has 16 neutrons, its atomic mass would be the total of the protons and neutrons. For example, if the atom has 8 protons, the atomic mass would be 16 (neutrons) + 8 (protons) = 24.
The atomic mass of an atom is the total mass of protons, neutrons, and electrons in the atom, measured in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the atom's nucleus.
The atomic mass.
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)
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
Protons, neutrons, and electrons can form any type of atom on the Periodic Table of Elements.The amount of protons determine what type of element an atom is.If the number of neutrons differ from the stable amount it should have, the atom is known as an isotope.If the amount of electrons differ from the amount of protons, the atom is known as an ion.
mass number = protons + nuetrons
The mass number is the sum of protons + neutrons.
Protons and neutrons are contained within the nucleus of an atom. The nucleus is located at the center of the atom and it is where most of the atom's mass is concentrated. Electrons, which are negatively charged particles, orbit around the nucleus in electron shells.
Mass number!:)
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
It depends on the amount of electrons in the outer shells. The neutrons do not affect the charge of an atom as they are already neutron. There is only a charge if there is a difference in protons and electrons, not protons and neutrons.
The mass number in chemistry represents the total number of protons and neutrons in an atom's nucleus. It is used to identify isotopes of an element, where different isotopes have the same number of protons but a different number of neutrons.
Number of protons + Number of neutrons = Mass number(number of nucleons)
