Ion: an atom with a charge Cation: positive ion (metals) Anion: negative ion (nonmetals) Electrostatic Attractions: forces holding positives and negatives together Ionic Bond: bond between a metal and a nonmetal exchanging electrons Metal: atoms to the left of the staircase in the PT Metallic Bond: positive ions sitting in a “sea” of electrons (electron-sea model) Crystal Lattice: a structure formed by ionic compounds Covalent Bond: bond between nonmetals only sharing electrons Valence Electrons: the electrons in the outer most orbitals that are most responsible for an Lewis Dot Diagram: chemical symbol with valence electrons as dots Ball-and-stick model: 3D models of molecules Octet Rule: the notion that each atom is most stable when it’s outer orbitals are full (usually with 8 electrons) Group: a vertical column of the PT (group #’s = valence electrons) Period: a horizontal row of the PT Ion: an atom with a charge Cation: positive ion (metals) Anion: negative ion (nonmetals) Electrostatic Attractions: forces holding positives and negatives together Ionic Bond: bond between a metal and a nonmetal exchanging electrons Metal: atoms to the left of the staircase in the PT Metallic Bond: positive ions sitting in a “sea” of electrons (electron-sea model) Crystal Lattice: a structure formed by ionic compounds Covalent Bond: bond between nonmetals only sharing electrons Valence Electrons: the electrons in the outer most orbitals that are most responsible for an Lewis Dot Diagram: chemical symbol with valence electrons as dots Ball-and-stick model: 3D models of molecules Octet Rule: the notion that each atom is most stable when it’s outer orbitals are full (usually with 8 electrons) Group: a vertical column of the PT (group #’s = valence electrons) Period: a horizontal row of the PT Ion: an atom with a charge Cation: positive ion (metals) Anion: negative ion (nonmetals) Electrostatic Attractions: forces holding positives and negatives together Ionic Bond: bond between a metal and a nonmetal exchanging electrons Metal: atoms to the left of the staircase in the PT Metallic Bond: positive ions sitting in a “sea” of electrons (electron-sea model) Crystal Lattice: a structure formed by ionic compounds Covalent Bond: bond between nonmetals only sharing electrons Valence Electrons: the electrons in the outer most orbitals that are most responsible for an Lewis Dot Diagram: chemical symbol with valence electrons as dots Ball-and-stick model: 3D models of molecules Octet Rule: the notion that each atom is most stable when it’s outer orbitals are full (usually with 8 electrons) Group: a vertical column of the PT (group #’s = valence electrons) Period: a horizontal row of the PT Ion: an atom with a charge Cation: positive ion (metals) Anion: negative ion (nonmetals) Electrostatic Attractions: forces holding positives and negatives together Ionic Bond: bond between a metal and a nonmetal exchanging electrons Metal: atoms to the left of the staircase in the PT Metallic Bond: positive ions sitting in a “sea” of electrons (electron-sea model) Crystal Lattice: a structure formed by ionic compounds Covalent Bond: bond between nonmetals only sharing electrons Valence Electrons: the electrons in the outer most orbitals that are most responsible for an Lewis Dot Diagram: chemical symbol with valence electrons as dots Ball-and-stick model: 3D models of molecules Octet Rule: the notion that each atom is most stable when it’s outer orbitals are full (usually with 8 electrons) Group: a vertical column of the PT (group #’s = valence electrons) Period: a horizontal row of the PT
