Term | Definition |
---|---|
Electron configuration | the arrangement of electrons in an atom |
Covalent bond | a bond formed when atoms share one or more pairs of electrons |
ionic bond | a force that attracts electrons and has a negative or postive charge |
ion | an atom radical or molecule that has gained or lost one or more electrons and has a negative or positive change |
Lewis dot structure (electron-dot notation) | an electron confidguration notation in which oonbly the valence electrons of an atom of a particular element are shown indicated by dotd placed around the elemnents symbol |
Octet rule | an atom will be most stable when surrounded by 8 electrons in the valence shell (outer most energy level) |
metallic bond | a boond formed by the attraction between positively charged ,etals ions and the electrons around then |
conductivity | Material that is able to conduct electricity |
polar | describes a molecule in hwich the postive abnd negative chRGES ARE SEPARETED |
nonpolar | a covalent bond in which the bonding electrons are equally attracted to both bonded atoms |
bent | molecular shape |
tetrahedral | molecular shape |
trigonal planar | molecular shape |
linar | molecular shape |
valence electrons | an electron that is found ion tyhe outermost shell of an atom and that determines th atoms chemical properties |
formula unit | the simpliest collection of atoms from which an ionic compounds formula can be written |
polyatomic ion | an ion made of two or more atoms |
VSEPR theory | a theoryt that predicts some molecualr sdjaped bsed on the idea that pairs of valence electrons surrounding an atom repel each other |
