Unit 14 vocabulary- nuclear chemistry
A particle with two protons and two neutrons, with a 2+ charge; is equivelant to a helium -4 nucleus, can be represented by “a”; emmited during radioactive decay
Radiation that is made up of alpha particles; is deflected toward a negatively charged plate when radiation from a radioactive source is directed between two electrically charged plates.
A high speed electron with a 1-charge that is emitted during radioactive decay.
Radiation that is made up of beta particles; is deflected toward a positively charged plate when radiation from a radioactive source is directed between two electrically charged plates.
High energy radiation that has no electrical charge and no mass, is not deflected by electric or magnetic fields, usually accompanies alpha and beta radiation and accounts for most of energy lost during radioactive decay
The time required for one-half of a radioisotopes nuclei to decay into its products.
Radiation that is energetic enough to ionize matter it collides with.
The splitting of a nucleus into smaller, more stable fragments, accompanied by a large release of energy.
The process of binding smaller atomic nuclei into a single, larger and more stable nucleus.
The positively charged protons and neutral neutrons contained in an atom’s nucleus.
A particle that has the same mass as an electron but an opposite charge.
A radioactive decay process in which a proton in the nucleus is converted into a neutron and a positron and then a positron is emitted from the nucleus.
The Rays and particles— alpha and beta particles and gamma rays—they are emitted by radioactive waves.
A spontaneous process in which unstable nuclei lose energy by emitting radiation.
Radioactive decay series
A series of nuclear reactions that starts with an unstable nucleus and results in the formation of a stable nucleus.
The process in which some substances spontaneously emit radiation.
Isotopes of atoms that have unstable nuclei and emit radiation to attain more stable atomic configurations.
