Therefore, <b>the number of protons is 47</b>. If the element is neutral, it must have the same number of electrons as protons to ensure the sum of the charges is zero. Therefore, <b>it has 47 electrons</b>. To determine the number of neutrons, subtract the atomic number from the atomic mass, which is the sum of protons and neutrons: <br/> <br/> (108 - 47) = <b>61 neutrons</b>.</p></div> https://ejercicios-fyq.com/Atomic-number-and-atomic-mass-3444 https://ejercicios-fyq.com/Atomic-number-and-atomic-mass-3444 2016-01-06T04:08:49Z text/html es F_y_Q Atomic mass Atomic number SOLVED <p>An element has an atomic number of 10 and an atomic mass of 20.

By subtracting the number of protons from the atomic mass, you can determine the number of neutrons. <br/> <br/> Z = 10 ('Z' represents the number of protons) and A = 20 ('A' represents the total number of protons and neutrons): <br/> <br/> Number of neutrons is (A - Z): <br/> <br/> Neutrons = 20 - 10 = <b>10 neutrons</b>.</p></div>
