All NEUTRAL atoms have an equal number of protons and neutrons. The atoms on the Periodic Table are assumed to be neutral.
For example: carbons atomic number is 6 because it has 6 protons. So if it is neutral it will also have 6 neutrons. So its Atomic Mass is basicly 12. But you could also find carbon 14 in the world which would have 6 protons and 8 neutrons. This would be called an isotope of carbon.
NOTE: only the number of neutrons can change in an atom, never protons. The number of protons define the element.
Yo answer your question: All atoms and their atomic mass as seen on the periodic table are an average of that type of element you would find on earth. So in other words, almost all the carbon on earth is carbon 12.
So the average number of neutrons you would find in carbon is 6.
Another way to look at it: If most of the elements on earth are neutral and have equal protons and neutrons. Then you could just say the atomic number of an atom would also be the average number of neutrons you will find in that element type. Hydrogen 1 neutron, helium 2, lithium 3 and so on...

How do you find the number of protons and neutrons in an element?
iron
How do you find the number of neutrons in a element using only mass and the element name?
Look up the name on the periodic table and subtract the atomic number from the mass number (which is protons and neutrons). That will give you the number of neutrons.
How many neutrons are in the nucleus of a atom?
Atomic nuclei are composed of protons and neutrons. The atomic number of an element shows the number of protons in a nucleus of an atom of that element, while the atomic mass shows the average number of nucleons (either a proton or a neutron) in nuclei of that element. There can be an average because, unlike proton number, neutron number can vary from isotope to isotope. For example, carbon can have 6 or 7 neutrons and still be stable, but it always has to have 6 protons, or else it'd be a different element. Because atomic mass is equal to the number of protons and neutrons, one can find the number of neutrons by subtracting the number of protons from the total number of nucleons in a given isotope. To do this, subtract the atomic number from the atomic mass.
How do you calculate the number of neutrons an atom of a specific element has?
First, find its atomic mass on the periodic table and subtract the number of protons (element number) from it and there you go
How do you find neutrons and protons in an ion element for iron?
the protons will be the atomic number, in this case 26. The neutrons depends on which isotope. The most common isotope is iron-56, so that will have 30 neutrons. If the element is written in symbolic notation, the number on the top, minus the number on the bottom is the number of neutrons.
How do you find the number of nucleons?
To find the number of neutrons in an atom, first find the atomic weight of the element and round that number to the nearest whole number. Then, find the atomic number of the element. Subtract that number from the atomic weight and the number of neutrons will be found.
What equation do you use to find the number of neutrons in an element?
Number of neutrons = mass number - number of protons
How do you find the number of protons and neutrons in an element?
iron
How do you find the number of neutrons in a element using only mass and the element name?
Look up the name on the periodic table and subtract the atomic number from the mass number (which is protons and neutrons). That will give you the number of neutrons.
How do you find out mass number of an element?
Mass number = Number of Protons + Number of Neutrons
How do you find the mas number of an element?
The mass number is the sum of protons and neutrons.
How do you find the mazz number of an element?
The mass number is the sum of protons and neutrons.

How do you find the number of neutrons on an element?
use a periodic table look at the atomic number
How many neutrons does suflur have?
Sulfur has 16 neutrons. To find out how many neutrons an element has you subtract the atomic number of that element by the atomic mass. omg thank you so much
How do you find the number of neutrons in an atom if that number is not told to you?
if you arent given the atomic numbert for an element - where could you find it?
How are the numbers of neutrons calculated from the period table?
You can find the number of neutrons present in any individual element by subtracting the atomic number from the mass number.
