Typically to find the number of neutrons, you first round the Atomic Mass to the nearest whole number. After that to you subtract the number of protons (which is the same as the atomic number) from the newly rounded atomic mass and the resulting number is the number of neutrons. lets use Carbon for example:
Atomic mass: 12.01
Atomic mass rounded: 12.00
Number of Protons (same as atomic number): 6
(Rounded atomic mass - number of protons)=6
So Carbon has 6 neutrons.
Hope that is easy enough to understand.

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.
How many protons electrons and neutrons are in Ag?
The number of protons in a atom is equal to the atomic number, therefor Ag has 47 protons. The number of protons and neutrons in an atom is equal to the atomic mass, therefor (108-47= 61) Ag has 61 neutrons. The number of electrons is equal to the number of protons therefor Ag has 47 electrons.
What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
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.
Which's the statement about atoms?
the number of neutrons and protons are equal
Why must the number of protons and neutrons be equal?
The number of protons and neutrons is not equal. The equality is not a rule.
Are the number of neutrons equal to the atomic number minus the atomic mass?
false
An equal number of protons and neutrons typically results in an atom that is?
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
Does the number of neutrons equal the mass number?
no, the mass number is number of protons in an atom, plus the number of neutrons.
Do neutrons always equal the number of elecrons?
Electrons are equal to the number of protons and the atomic number. To find the number of neutrons you must subtract the atomic number from the mass number.
Does the number of neutrons always equal the number of protons?
No
An atom does not have to have equal numbers of?
The mass number can differ within the same element becasue the number of neutrons can change.
Do electrons equal the sum of the number of neutrons and protons in an isotope?
No. The number of neutrons has no affect on the number of protons and electrons.
Is the difference between the mass number of an isotope and its atomic number is equal to the number of nucleons in the nucleus?
It is equal to the number of neutrons in the nucleus, not nucleons (which include both protons and neutrons.)
What is the symbol of barium and number of neutrons?
The symbol is Ba. The number of neutrons equal the number of protons.
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
What equal to the number of protons and neutrons in an atom?
mass number
