What is the total amount of protons and neutrons in an atom called?

The atomic mass.


What is the difference the atomic number of 6 of an atom and it's mass number?

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)


What is equal to the total number of protons and 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 combine to form what?

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.


What is the total number of protons and neutron's in an atom called?

mass number = protons + nuetrons


The mass number of an atom indicates the number of what?

The mass number is the sum of protons + neutrons.


Where are protons and neutrons of an atom contained?

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.


What is the sum of protons and neutrons in an atom?

What is the mass number of 10 protons and 10 neutrons?

20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.


Does an atom have a charge if the neutrons equals the protons?

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.


What does the Mass number in chemistry represent?

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.


What is the name number tells you the amount of protons and neutrons in an element?

Number of protons + Number of neutrons = Mass number(number of nucleons)
