what is the calculation of the number of neutrons in an atom with 6 protons and the mass number of 13th
To calculate the number of neutrons from an atom that has 6 protons and has a mass number of 13, is by using the following equation. Mass number - no. of protons = no. of neutrons 13 - 6 = 7. There are 7 neutrons present in this atom that has an atomic number of 6 protons.
