An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
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.
The mass number of an atom is equal to?
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
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.
An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
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.
Is the atomic mass equal to the number of atoms in the elements?
The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.

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.
What is the sum of protons and neutrons in an atom?
Mass number!:)
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 number is the atomic mass equal to?
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
What is the sum if the masses of the atoms present in the formula of an ionic compound?
The sum of the masses of the atoms in an ionic compound is equal to the formula mass of the compound. It is calculated by adding the atomic masses of all the atoms present in the formula unit.
