Term | Definition |
---|---|
ATOMIC MASS | Mass of an atom Equal to the sum (total)of its protons & neutrons |
CHEMICAL REACTION | Chemical change process Occurs when bonds are broken and new bonds are formed |
CONSERVATION of MATTER | Neither matter (mass) nor energy Can be lost or destroyed in a chemical reaction |
COVALENT BOND | Formed when 2 or more “NONMETALS” share valence electrons To have “full” octet (8 electrons) |
FISSION | Splitting of an atomic nucleus Releasing large amounts of energy |
FUSION | Joining (melting together) of atomic nuclei Forms heavier nuclei Releases enormous energy |
ION (Ionization) | Charged particle Formed when an atom gain or loses one or more electrons May be negative or positive |
IONIC BOND | Bond formed Transfer between metals to nonmetals Forming OPPOSITE charge(s) Strongly attracted to each other |
METALLIC BOND | Bond Formed Large number of metal atoms Share valence electrons |
