| Questions | Answers |
|---|---|
| Chemical Bond | a mutual electrical attraction between the nuclei and valence electrons or different atoms that binds the atoms together |
| Ionic Bonding | the chemical bond resulting from electrical attraction between large numbers of cations and anions |
| Covalent Bonding | a chemical bond resulting from sharing of an electron pair between two atoms |
| Polar | having an uneven distribution of charge |
| Polar-Covalent Bond | a covalent bond in which the bonding electrons are shared equally by the bonded atoms resulting in a balanced distribution of electrical charge |
| Bond Energy | the energy required to break a chemical bond and form neutral isolated atoms |
| Chemical Formula | a formula that indicated the relative numbers of atoms of each kind in a chemical compound by using atoms symbols and numerical subscriptions |
| Diatomic Molecule | a molecule containing only two atoms |
| Double Bond | a covalent bond produced by the sharing of two pairs of electrons between two atoms |
| Electron-Dot notation | an EC notation in which the only valence electrons of an atom of a particular element are shown indicated by dots placed around the elements symbol |
| Lewis Structures | formula in which atomic symbols represent nuclei and inner-shell electrons, dot pairs, or dashes between two atomic symbols represent electron pairs in covalent bonds and dots adjacent to only one atomic symbol represent unshaved electrons |
| Lone Pair | a pair of electrons that is not involve in bonding and that belong exclusively to one atom |
| Molecular Compound | a chemical compound whose simplest units are molecules |
| Molecular Formula | a formula showing they types and numbers of atoms combines in a single molecule of a molecular compound |
| Molecule | a neutral group of atoms that are held together by covalent bonds |
| Multiple Bond | a double or triple bond |
| Octet Rule | chemical compunds tend to form so that each atoms by gaining losing or sharing electrons has an octet of electrons in its highest occupied energy level |
| Resonance | the bonding in molecules orions that cannot be correctly represent by a single lewis structure |
| Single Bond | covalent bond produced by the sharing of one pair of electrons between two atoms |
| Structural Formula | a formula that indicates the number and typed of atoms present in a molecule and also shows the bonding arrangement if the atoms |
| Triple Bond | a covalent bond produced by the sharing of three pairs of electrons between two atoms |
| Unshared Pair | a pair of electrons that is not involved in bonding and that belongs exclusively to one atom |
| Formula Unit | the simplest collection of atoms from which an ionic compounds formula can be established |
| Ionic Compound | a compound imposed of positive and negatice ions that are combined so that the numbers of positive and negative charges are equal |
| Lattice Energy | the energy released when one mole of an ionic crystalline compound is formed from gaseous ions |
| Polytomic Ion | a charge group of covalently bonded atoms |
| Ductility | the ability of a substance to be drawn pulled or extruded through a small opening to produce a wire |
| Malleability | the ability of a substance to be hammered or beaten into thin sheets |
| Metallic Bonding | a chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons |
| Dipole | equal but opposite charges that are separated by a short distance |
| Dipole-Dipole Forces | a force of attraction between polar molecules |
| Hybrid Orbitals | orbitals of equal energy produced by the combinations of two or more orbitals on the same atom |
| Hybridization | the mixing of two or more atomic orbitals of similar energy on the same atoms to produce new orbitals on the same atom |
| Hydrogen Bonding | intermolecular force in which a hydrogen atom that is bonding to a highly EN atom is attracted to an unshared pair of electrons of an EN atom nearby molecule |
| Intermolecular Forces | the force of attraction between molecules |
| London Dispersion Forced | an IM attraction resulting from the constant motion of electrons and the creation of instantaneous dipoles |
| Molecular Polarity | the uneven distribution of molecular charges |
| VSEPR Theory | the repulsion between the sets of valence electron surrounding an atom causes these sets to be oriented as far apart as possible |
