Nuclides Nuclide = a particular type of nucleus, characterized by a specific atomic number and nucleon number Nucleon number or mass number = the number of nucleons (protons and neutrons) in the nucleus of a nuclide.

Nuclear Stability Electrostatic force = the force that causes opposite electrical charges to attract each other. Strong force = the force between nucleons (protons and neutrons). • Neutrons increase the attraction from the strong force without increasing electrostatic repulsion between nucleons.

Nuclear Reactions • Nuclear reactions involve changes in the nucleus, whereas chemical reactions involve the loss, gain, and sharing of electrons. • Different isotopes of the same element may undergo very different nuclear reactions, even though an element’s isotopes all share the same chemical characteristics.

Nuclear Reactions (2) • Unlike chemical reactions, the rates of nuclear reactions are unaffected by temperature, pressure, and the presence of other atoms to which the radioactive atom may be bonded. • Nuclear reactions, in general, give off much more energy than chemical reactions
