This equation is:
Mass number - number of protons = number of neutrons
Mass number is the sum of protons and neutrons and has a value near the Atomic Mass of an isotope.

What are Atoms that vary in the number of neutrons found in their nuclei called?
Different elements with same number of neutrons are known as isotones.
How do you find the number of neutrons protons and electrons in an atom if the atom is neutral?
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
How many protons and neutrons does a diamond have?
A diamond is composed of carbon atoms. The atomic number of carbon is 6, so all carbon atoms have 6 protons in their nuclei. The number of neutrons depends on the isotope of carbon. Carbon-11 atoms have 5 neutrons, carbon-12 atoms have 6 neutrons, carbon-13 atoms have 7 neutrons, and carbon-14 atoms have 8 neutrons. Refer to the related links below to see the Wikipedia articles on carbon and diamond.
How many protons nuetrons and electrons does argon have?
In order to answer this question, the specific isotope of argon must be known. However, I will answer it using argon-40 because it makes up over 99% of the atoms of argon. Argon-40 has a mass number of 40, meaning that the sum of protons and neutrons in the nuclei of its atoms is 40. In order to use this information to determine the numbers of protons and neutrons, you also need to know the atomic number, which is the number of protons in the nucleus of its atoms. Argon's atomic number is 18, so we know that all argon atoms have 18 protons. To calculate the number of neutrons, we subtract the atomic number from the mass number, which is (40-18)=22 neutrons. The number of electrons equals the number of protons in a neutral atom, so argon atoms have 18 electrons. So, to sum things up, neutral atoms of argon-40 contain 18 protons, 22 neutrons, and 18 electrons.
Which's the statement about atoms?
the number of neutrons and protons are equal
How do you calculate a balanced chemical equation?
The number of reactants atoms must be equal to the number of products atoms.
Oxygen has eight protons in its nucleus. calculate the number of neutrons and electrons in a neutral oxygen 16 atoms?
Oxygen-16 has 8 electrons and 8 neutrons.
How can an atoms number of neutrons be determined?
Mass number-Atomic Number= Number of neutrons
How do you find the number of neutrons in an elements atoms?
number of neutrons = mass number - atomic number
Do atoms have neutrons in them?
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
What are Atoms that vary in the number of neutrons found in their nuclei called?
Different elements with same number of neutrons are known as isotones.
What do you notice about the number of atoms on each side of a chemical equation?
That the number of atoms on the left side of the equation must be the same number of atoms that are on the right side of the equation.
Do all of the atoms of the same element have the same number of neutrons?
Yes, all atoms of the same element have the same number of neutrons.
What atomic particle that determines a specific isotope?
The atomic particle that determines a specific isotope is the number of neutrons in the nucleus of an atom. Isotopes are different forms of an element that have the same number of protons but a different number of neutrons. The number of neutrons affects the mass of the atom and gives rise to different isotopes with varying atomic weights.
What does the equation N equals A-Z mean?
N represents the number of neutrons in an atom, A represents the atom's mass number and Z is the atoms proton number. This makes sense because it shows that the mass number of an atom is the number of protons added to the number of neutrons in the nucleus.
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Atoms which have different number of protons and neutrons but have the same molecular weight are called Isobars.
