How To Find The Number Of Protons Neutrons And Electrons First, to find the number of protons, we need to realize that the neutral atom had 53 electrons because it is the additional one electron that makes it a 1 anion. now, because the atom has 53 electrons, it must also have 53 protons, and to find the number of neutrons we subtract this from the mass number. # n = a – # p = 127 – 53 = 74. Make sure that you round the atomic mass to the nearest whole number. for example, the atomic mass of boron is 10.811, but you can just round the atomic mass up to 11. 6. subtract the atomic number from the atomic mass. to find the number of neutrons, you will need to subtract the atomic number from the atomic mass.

How To Find The Number Of Protons Neutrons And Electrons Finding the number of neutrons. the number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. both of these numbers can be found on the periodic table. the atomic number is listed above the symbol of the element whereas the mass number is placed below. let’s keep using oxygen as our example. This chemistry video tutorial explains how to calculate the number of protons, neutrons, and electrons in an atom or in an ion. it also explains the differe. Find the atomic number (z) and mass number (a). they are equal to 11 and 23, respectively. calculate numbers of protons, neutrons, and electrons by using mathematical expressions (1 3): p = 11 (1) n = 23 11 = 12 (2) e = 11 0 = 11 (3) alternatively, you can also calculate the atomic number, atomic mass, and charge. Protons. a proton is one of three main particles that make up the atom. protons are found in the nucleus of the atom. this is a tiny, dense region at the center of the atom. protons have a positive electrical charge of one ( 1) and a mass of 1 atomic mass unit (amu), which is about 1.67 × 10 − 27 kilograms.

An atom close atom an atom is the simplest particle of an element that can exist on its own in a stable environment. has no overall charge, because it has an equal number of protons and electrons. Mass number = # of protons # of neutrons. mass number = 1 2. therefore, this particular atom of hydrogen will have a mass number of 3. note that the mass number calculated in example 2.4.1 2.4. 1 does not match the number underneath the elemental symbol and name for hydrogen on the periodic table.
