The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is).
The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope.
The number of protons and neutrons added together is called the Atomic Mass.

The combined number of protons and neutrons?
Number protons + number neutrons is called the mass number or the atomic mass.
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
How many neutrons are in magnesium 25?
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
An atoms what number is the sum of protons and neutrons?
The sum of protons and neutrons in an atom is called mass number.
Atoms that have different number of protons and neutrons are called?
Atoms which have different number of protons and neutrons but have the same molecular weight are called Isobars.
What is the total number protons and neutrons in an atom called?
mass number = protons + nuetrons
What are elements having same number of protons and neutrons called as?
Carbon Number of Protons/Electrons: 6 Number of Neutrons: 6
The number of protons and neutrons is called?
The atomic mass
What are the different numbers of neutrons called when two atoms have the same number of protons?
Two atoms with the same number of protons but different numbers of neutrons are called "isotopes".
The combined number of protons and neutrons?
Number protons + number neutrons is called the mass number or the atomic mass.
What is the total number of protons and neutron's in an atom called?
mass number = protons + nuetrons
What is the sum of the protons and the neutrons in a nucleus called?
Mass number
What is the mass number minus the atomic number called?
Nucleon Number (total number of protons and neutrons)
Is there a relationship between the number of neutrons and protons in the atom is so what type?
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
