The three major types of radioactivity are: # Alpha Radiation Alpha radiation consists of a stream of positively charged particles, called alpha particles, which have an Atomic Mass of 4 and a charge of +2 (a helium nucleus). When an alpha particle is ejected from a nucleus, the mass number of the nucleus decreases by four units and the atomic number decreases by two units. For example: 23892U -> 42He + 23490Th The helium nucleus is the alpha particle. # Beta Radiation Beta radiation is a stream of electrons, called beta particles. When a beta particle is ejected, a neutron in the nucleus is converted to a proton, so the mass number of the nucleus is unchanged, but the atomic number increases by one unit. For example: 23490 -> 0-1e + 23491Pa The electron is the beta particle. # Gamma Radiation Gamma rays are high-energy photons with a very short wavelength (0.0005 to 0.1 nm). The emission of gamma radiation results from an energy change within the atomic nucleus. Gamma emission changes neither the atomic number nor the atomic mass. Alpha and beta emission are often accompanied by gamma emission, as an excited nucleus drops to a lower and more stable energy state. Alpha, beta, and gamma radiation also accompany induced radioactivity. Radioactive isotopes are prepared in the lab using bombardment reactions to convert a stable nucleus into one which is radioactive. Positron (particle with the same mass as an electron, but a charge of +1 instead of -1) emission isn't observed in natural radioactivity, but it is a common mode of decay in induced radioactivity. Bombardment reactions can be used to produce very heavy elements, including many which don't occur in nature.

The three main types of radioactivity are alpha, beta, and gamma radiation. Alpha radiation involves the emission of alpha particles (helium nuclei), beta radiation involves the emission of beta particles (high-energy electrons or positrons), and gamma radiation involves the emission of gamma rays (high-energy electromagnetic radiation).
Radioactivity is the emission of radiation from an unstable atomic nucleus.
Starch is composed of only carbon, hydrogen, and oxygen atoms. Hence, the different kinds of atoms present in starch are limited to these three elements.
Marie Curie, Pierre Curie, and Henri Becquerel are notable scientists who made significant contributions to the understanding of radioactivity. Marie Curie's work on radioactivity earned her two Nobel Prizes in Physics and Chemistry.
Marie Curie, Pierre Curie, and Henri Becquerel were key scientists involved in the discovery of radioactivity in the late 19th and early 20th centuries. Marie Curie's work with radioactive materials led to her pioneering research on radioactivity for which she was awarded Nobel Prizes in Physics and Chemistry.
Yes, there is a difference. Radioactivity refers to the property of certain elements to emit radiation, while radioisotopes are versions of elements that have an unstable nucleus and emit radiation as they decay. Radioactivity is a general phenomenon, while radioisotopes are specific isotopes of elements that exhibit this property.
