WebJun 18, 2024 · For all atoms with no charge, the number of electrons is equal to the number of protons. number of electrons = 30. The mass number, 65, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons = 65 − 30 = 35. Exercise 2.3. 3. WebAll isotopes of uranium are radioactive. Naturally occurring uranium contains three isotopes, namely 238U, 235U, and 234U. 235U and 238U are the origin of two different decay chains. All uranium isotopes have the same chemical properties because they all have the same number of protons (92), but different radiological properties. The
