BONDING vocab words
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 from one atom to another, which transforms a neutral atom into an ion |
Ion | An atom, radical, or molecule that has gained or lost one or more electrons and has a negative or positive charge |
Lewis Dot Structure(electron-dot notation) | An electron configuration notation in which only the valence electrons of an atom of a particular element are shown, indicated by dots placed around the element's symbol |
Octet Rule | an atom will most be stable when surrounded by 8 electrons in the valence shell (outer most energy level) |
Metallic Bond | A bond formed by the attraction between positively charged metal ions and the electrons around them |
Conductivity | Material that is able to conduct electricity |
Polar | describes a molecule in which the positive and negative charges are separated |
Non-polar | a covalent bond in which the bonding electrons are equally attracted to both bonded atoms |
Bent | Atoms have 2 bonded to central atoms and have 1 Lone pair of electrons |
Tetrahedral | Atoms have 4 bonded to central atoms and have 0 Lone pair of electrons |
Trigonal Planer | Atoms have 3 bonded to central atoms and have 0 Lone pair of electrons |
Linar | Atoms have 2 bonded to central atoms and have 0 Lone pair of electrons |
Valence Electrons | an electron that is found in the outermost shell of an atom and that determines the atom's chemical properties |
Formula Unit | the simplest collection of atoms from which an ionic compound's formula can be written |
Polyatomic Ion | an ion made of two or more atoms |
VSEPR Theory | a theory that predicts some molecular shapes based on the idea that pairs of valence electrons surrounding an atom repel each other |
