The nucleons in an atom: a. Reduce following beta-positive (b+) deca

1.	The nucleons in an atom: a. Reduce following beta-positive (b+) decay b. Are equal to the atomic number c. Are equal to the difference between mass number and the number of protons d. May have a negative charge e. Affect the binding energy of electrons
Answer» a. False. Nucleon is a term used to describe protons and neutrons. Beta-positive decay results in the conversion of a proton to a neutron plus an electron. Hence, the number of nucleons is unchanged. b. False. The nucleons equal the atomic mass (i.e. protons þ neutrons). c. False. The difference between mass number and the number of protons is equal to the number of neutrons. d. False. Protons have a positive charge and neutrons have no charge. e. True. The number of protons (i.e. atomic number) influences the binding energy.
