# Problem: How many neutrons are found in one atom of 36Cl? Express your answer numerically.Periodic table The periodic table lists two main numbers for each element. The atomic number is an integer that equals the number of protons. The number of neutrons is not given in the periodic table because it will vary with different isotopes. The mass number of an element is the sum of the protons and neutrons. To find the number of neutrons, the atomic number must be subtracted from the mass number. Elemental symbol When writing the symbol for an element, a superscript indicates the mass number and a subscript indicates the atomic number. For example, 146C has a mass number of 14 and an atomic number of 6. This isotope can also be written as just 14C. You do not need to put in the 6 because the atomic number of carbon is always 6 regardless of which isotope you are dealing with

How many neutrons are found in one atom of 36Cl?

Periodic table

The periodic table lists two main numbers for each element. The atomic number is an integer that equals the number of protons. The number of neutrons is not given in the periodic table because it will vary with different isotopes. The mass number of an element is the sum of the protons and neutrons. To find the number of neutrons, the atomic number must be subtracted from the mass number.

Elemental symbol

When writing the symbol for an element, a superscript indicates the mass number and a subscript indicates the atomic number. For example, 146C has a mass number of 14 and an atomic number of 6. This isotope can also be written as just 14C. You do not need to put in the 6 because the atomic number of carbon is always 6 regardless of which isotope you are dealing with
