An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
What makes an atoms mass number?
An atom's mass number is the sum of the numbers of protons and of neutrons in the atom.
Which term describes the sum of the number of protons and neutrons in an atom?
when you could check in most of atoms that we have you will see that the sum of protons and electrons equals to or is called the atomic weight or atomic mass...that is if you add protons to electrons you have your atomic mass.
What is the sum of a number of protons plus the number of neutrons?
Since the mass of one proton or one neutron is almost exactly equal to 1 gram per mole, and the mass of an electron is negligible, the atomic mass of 1 mole atoms can be found by adding the number of protons and neutrons it contains.

The mass number of an element is equal to what of an element?
The sum of the number of protons and the number of nuetrons.
How can an atoms mass number be determined?
it is the sum of the protons and neutrons present in the nucleus of the atom.
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
The atomic mass of an atom is equal to the sum of numbers of what?
protons + electrons= atomic mass NUMBER, not the atomic mass.
What does the atomic mass number of an atom tell you about the atom?
The mass number of an atom is equal to the sum of its number of protons and neutrons, simply, nucleons.
