Nuclear Chemistry Vocabulary Crossword

The ability of radiation to pass through matter
Isotopes of atoms with unstable nuclei
A form of high energy electromagnetic radiation emitted from some materials that are in an excited electron state
High energy radiation that accounts for most of the energy lost during radioactive decay
Radiation that is made up of alpha particles and is deflected toward a negatively charged plate when radiation from a radioactive source is directed between two electrically plates
Radiation that is made up of beta particles and is deflected toward a positively charged plate when radiation from the radioactive source is directed between two electrically charged plates
A radioactive decay process that occurs when an atom's nucleus draws in a surrounding electron, which combines with a proton to form a neutron, resulting in an x-ray photon being emitted
The time required for one-half of a radioisotope's nuclei to decay into its products
Protons and neutrons
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 the positron is emitted from the nucleus
A series of nuclear reactions that starts with an unstable nucleus and results in the formation of a stable nucleus
The process that is used to determine the age of an object by measuring the amount of a certain radioisotope remaining in that object
A force that acts on subatomic particles that are extremely close together and overcomes electrostatic repulsion among protons
A reaction in which an atom's atomic number is altered
A nuclear reactor that is able to produce more fuel than it uses
The minimum mass of a sample of fissionable material necessary to sustain a nuclear chain reaction
The difference in mass between a nucleus and its component nucleons
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
A nuclear fusion reaction
The process in which nuclei are bombarded with high-velocity charged particles in order to create new elements
An element with an atomic number of 93 or greater on the periodic table
Radiation that is energetic enough to ionize matter it collides with
An isotope that emits non-ionizing radiation and is used to signal the presence of an element or specific substance
