Did you know?
WebOct 29, 2024 · Explanation: An alpha particle is a Helium ion with a charge of +2. The number of protons is 2 and the number of neutrons is 2. The total mass is 4. When an alpha particle is emitted the mass number goes down by 4 and the atomic number goes down by 2. So 214 − 4 = 210 for the mass number 84 −2 = 82 for the atomic number.
