You're on a roll — Here are the definitions from your notes: Radioactivity: Radioactivity is the spontaneous decay or disintegration of the nucleus of an atom of an element. Radioactive elements: Radioactive elements are those elements that spontaneously emit radiation from their nucleus, e.g., radium, thorium, uranium, potassium. Half-life: Half-life of a radioactive element is the time taken for half of the atoms initially present in the element to decay. Nuclear energy: Nuclear energy is defined as an energy used for generating electricity. Gravitational field: A gravitational field is a region in space around a mass within which the gravitational force of the mass can be experienced. What's next? Send 'em.
