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?
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
An atom of an element has 54 protons some of the elements atoms have 77 neutrons while other atoms have 79 neutrons what are the atomic numbers and mass numbers of the two types of atoms of this el?
The atomic number for an element with 54 protons is 54. For the atoms with 77 neutrons, the mass number would be 54 (protons) + 77 (neutrons) = 131. For the atoms with 79 neutrons, the mass number would be 54 (protons) + 79 (neutrons) = 133.
How many atoms of hydrogen appear on each side of the equation?
To determine the number of hydrogen atoms on each side of the equation, you would need to balance the equation first. Once the equation is balanced, count the number of hydrogen atoms on both the reactant and product sides to compare. The number of hydrogen atoms should be the same on both sides of the balanced equation.
Can you count the number of atoms in a chemical equation?
Yes, you can count the number of atoms in a chemical equation by taking into account the subscripts of each element within the formula. The subscripts represent the number of atoms of each element present in the molecule. By adding up the total number of each atom on both sides of the equation, you can determine the total number of atoms in the chemical equation.
Which number in a chemical equation shows you the number of atoms?
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
How do you calculate a balanced chemical equation?
The number of reactants atoms must be equal to the number of products atoms.
How many nuetrons is in lithium?
4 neutrons in the most stable isotope of lithium (3Li7)
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.
Do uncombined atoms have the same number of neutrons as protons?
Uncombined atoms have the same number of neutrons as protons only if they are isotopes of the element, which means the atoms have the same number of protons but different numbers of neutrons. Otherwise, atoms with the same number of protons and neutrons would be considered as different elements.
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?
Atoms are electrically neutral. The number electrons and number of protons in neutral atoms are same. The number of neutrons in some atoms are same as the number of protons. Example: Calcium atom contains 20 protons and 20 neutrons. But some atoms contain same number of protons but different number of neutrons. For example carbon atoms exist in three forms - all contain 6 protons but some contain 6 neutrons, some 7 neutrons and others with 8 neutrons. These type of atoms are known as isotopes Definition of isotope: Atoms with same number of protons but different number of neutrons It shows that the different number of neutrons determines the existence of isotopes.

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 are Atoms that vary in the number of neutrons found in their nuclei called?
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
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.
