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...
The number of protons in an element is equal to its atomic number, which is found on the periodic table. To find the number of neutrons, subtract the atomic number from the atomic mass of the element.
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the element). The atomic number can be determined from the element's position on the periodic table.
One quick way to find that out is to open the Wikipedia and type "Isotopes of Carbon", "Isotopes of Uranium", or whatever element you are interested in. Please note that each element has several different isotopes; the number of neutrons varies from one isotope to another.
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.
It is not possible.
The number of protons in an element is equal to its atomic number, which is found on the periodic table. To find the number of neutrons, subtract the atomic number from the atomic mass of the element.
Number of neutrons = mass number - number of protons
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the element). The atomic number can be determined from the element's position on the periodic table.
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the mass number (sum of protons and neutrons). Neutrons do not carry a charge and help stabilize the nucleus of an atom.
To find the number of nucleons in an atom, you add the number of protons and the number of neutrons together. Nucleons are the collective term for protons and neutrons found in the nucleus of an atom.
Mass number = Number of Protons + Number of Neutrons
To find the number of neutrons, subtract the atomic number from the mass number. In this case, you would calculate 244 - 94 = 150 neutrons.
The mass number is the sum of protons and neutrons.
The mass number is the sum of protons and neutrons.
To find the number of neutrons in an atom of a given element, you would typically subtract the atomic number (number of protons) from the atomic mass of the element. The atomic mass is usually represented as the decimal number on the periodic table for each element.
Atomic weight is really the only way to know how many neutrons there are. However, if you have no reason to think that you are dealing with an unusual isotope, you can assume the normal distribution of isotopes.
110. number of protons = mass number - neutrons = 271 - 261 = 110
