Although all atoms of the same chemical element comprise the same number of protons, their number of neutrons can vary. Knowing how many neutrons are in a item atom tin can help yous determine if it's a regular cantlet of that element or an isotope, which will accept either extra or fewer neutrons.^[one] Determining the number of neutrons in an atom is fairly unproblematic and doesn't even require whatsoever experimentation. To calculate the number of neutrons in a regular atom or an isotope, all you need to exercise is follow these instructions with a periodic table in mitt.

1

Locate the element on the periodic table. For this instance, nosotros'll look at osmium (Os), which is in the sixth row down.^[2]
2
Find the element'due south atomic number. This tends to be the about visible number pertaining to a given element and ordinarily sits to a higher place the element symbol, either in the center of the box or in the upper left corner. (On the chart we're using, in fact, no other numbers are listed.) The atomic number is the number of protons in a single atom of that element. ^[3] Bone is number 76, meaning i atom of osmium has 76 protons.
- The proton number never changes in an element; it's basically what makes that chemical element that element.^[iv]

three

Discover the element's atomic weight. This number is normally found beneath the atomic symbol. Note that the chart in this case is based solely on atomic number and doesn't list the atomic weight. This won't e'er usually be the case. Osmium has an atomic weight of 190.23.^[5]
4
Round off the diminutive weight to the nearest whole number to find the diminutive mass. ^[6] In our case, 190.23 would exist rounded to 190, resulting in an diminutive mass of 190 for osmium.
- The atomic weight is an average of the isotopes of the element, so that's why it's non usually a whole number.^[7]
5

Subtract the atomic number from the atomic mass. Since the vast majority of an atom's mass is fabricated up of its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. The numbers subsequently the decimal signal stand for the usually very small-scale mass of the electrons in the atom. In our instance, this is: 190 (atomic weight) – 76 (number of protons) = 114 (number of neutrons).^[viii]
half-dozen
Remember the formula. To find the number of neutrons in the hereafter, simply use this formula:^[9]
- N = Yard – north
  - Due north = number of Northwardeutrons
  - M = atomic Mass
  - northward = atomic number

ane

Locate the element on the periodic table. Every bit an case, we'll wait at the carbon-14 isotope. Since the non-isotopic form of carbon-14 is simply carbon (C), find carbon on the periodic table (in the 2d row down).^[x]
2

Find the element's atomic number. This tends to be the almost visible number pertaining to a given element and usually sits above the element symbol. (On our example chart, in fact, no other numbers are listed.) The atomic number is the number of protons in a unmarried atom of that chemical element. ^[11] C is number 6, meaning one atom of carbon has 6 protons.
iii

Notice the atomic mass. This is incredibly easy with isotopes, as they are named according to their atomic mass. Carbon-xiv, for example, has an atomic mass of xiv. In one case y'all find the atomic mass of the isotope, the procedure is the same as it is for finding the number of neutrons in a regular atom.^[12]
4

Subtract the atomic number from the diminutive mass. Since the vast bulk of an atom's mass is constitute its protons and neutrons, subtracting the number of protons (i.eastward. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. In our example, this is: 14 (atomic mass) – half-dozen (number of protons) = eight (number of neutrons).
5
Remember the formula. To find the number of neutrons in the future, simply apply this formula:^[thirteen]
- N = Chiliad – n
  - North = number of Neutrons
  - M = diminutive Thousandass
  - n = atomic number

Question

How many neutrons are in oxygen?

Atomic mass minus the atomic number. Diminutive mass of Oxygen is sixteen, and the diminutive number is viii. 16 - eight = 8.
Question

Where can I locate the atomic mass in a mod periodic tabular array?

The modern periodic table has the atomic number on the top of each chemical element's symbol and the atomic mass right below the symbol.

Protons and neutrons make up almost all of the weight of the elements, whereas electrons and miscellaneous particles represent negligible mass (budgeted goose egg mass). Since one proton has approximately the same weight as one neutron, and the atomic number represents the number of protons, we can simply subtract the number of protons from the total mass.^[14]

If you're always unsure which number is which in a periodic tabular array, only remember that the table is commonly designed effectually the atomic number (i.e. number of protons), which starts at ane (hydrogen) and ascends ane unit at a fourth dimension from left to right, ending at 118 (oganesson). This is because the number of protons in an atom determines what that atom is, making it the easiest elemental trait to organize by. (Ex. an atom with 2 protons is always helium, just as an atom with 79 protons is e'er aureate.)

Article Summary 10

To find the number of neutrons in an atom, you just need a periodic table that lists the atomic number as well as the atomic weight of each element. Kickoff, locate the elemental symbol for your atom on the periodic table. Then, find the atomic number for the chemical element. It'due south usually located somewhere higher up the chemical element symbol. This number represents the number of protons in the cantlet. For instance, the atomic number of niobium (Nb) is 41, meaning that a niobium atom has 41 protons. Next, observe the atomic weight of the element, which is commonly underneath the chemical element symbol. Round upwardly the atomic weight to the nearest whole number. Niobium has an atomic weight of 92.906, then you would round it up to 93. Finally, subtract the number of protons from the rounded up diminutive weight to find the number of neutrons in the atom. In the case of niobium, 93 minus 41 is 52, which means that a niobium atom has 52 neutrons. To find out how to calculate the number of neutrons in an isotope, read on!
