Chemical Bonding
| Term | Definition |
|---|---|
| Chemical Bond | the attractive force that holds atmos or ions together |
| Ionic bond | a force that attracts electrons and transforms a neutral atom into a ion |
| Covalent bond | a bond formed when atoms share |
| Nonpolar covalent bond | bonding electrons are equally attracted |
| Polar covalent bond | a pair of electrons is held closely |
| Molecule | the smallest union that keeps all of the physical and chemical properties |
| Molecular compound | simplest units of molecules |
| Chemical Formula | chemical symbols and numbers |
| Molecular Formula | shows the numbers and kids of atoms in a molecule |
| Bond energy | energy required to break the bonds in 1 mol |
| Electron dot notation | electron configuration in which only the valence electrons are shown |
| Lewis structure | electrons are represented by dots; dot pairs or dashes |
| Single Bond | two atoms share one pair of electrons |
| Multiple Bond | atoms share more than one pair of electrons such as double bond or triple bond |
| Resonance | Bonding that cannot be correctly represented by a single Lewis structure |
| Ionic compound | Composed of ions bound together |
| Structural formula | indicates the location of the atoms relative to one another in a molecule |
| Formula Unit | collection of atoms corresponding to a ionic compounds formula |
| Lattice energy | energy associated with constructing a crystal lattice |
| Polyatomic ion | Ion made of two or more atoms |
| Metallic bond | attraction between positively charged metal ions |
| Malleability | hammered or beaten into a sheet |
| Ductility | drawn out into a wire |
| VSEPR theory | predicts some molecular shapes based on the idea that pairs of valence electrons repel each other |
| Hybridization | mixing of two or more atomic orbitals |
| Hybrid orbitals | Orbitals that have properties that contain both positively and negatively charged regions |
| Hydrogen bond | occurring when a hydrogen atom that is bounded to a highly electronegative atom of one molecule |
| London dispersion force | resulting from the uneven distribution of electrons |
