|
Chemical bonding |
A mutual electrical attraction between the nuclei and valence electrons of different items that binds the atoms together |
|
|
Ionic bonding |
Chemical bonding that results from the electrical attraction between cations and anions. |
|
|
Covalent bonding |
results from the sharing of electron pairs between two atoms |
|
|
Nonpolar 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 |
|
|
Polar |
Bonds that having an uneven distribution of charge |
|
|
Polar covalent bond |
A covalent bond in which the bonded atoms have an unequal attraction to the shared electrons |
|
|
Molecule |
A neutral group of atoms that are held together by covalent bonds |
|
|
Molecular compounds |
Chemical compound whose simplest units are molecules |
|
|
Molecular formula |
Shows the types and numbers of atoms combined in a single molecular compound |
|
|
Bond energy |
The energy required to break a chemical bond and forms neutral isolated atoms |
|
|
Electron dot notation |
An electron configuration notation and which only the valence electrons of an atom of a particular element are shown indication by Dots placed around elements symbols |
|
|
Lewis structure |
formulas in which atomic symbols represent nuclei and inner shell electrons, dot paors or dashes between two atomic symbols represent electron pairs in covalent bonds and dots adjacent to only one atomic symbol represent unshared electrons |
|
|
Structural formula |
Indicates the kind, number arrangement, and bonds, but not the inshared pairs of the atoms in a molecule |
|
|
Single bond |
A covalent bond in which one pair of electrons is shared between two atoms |
|
|
Multiple bonds |
Double and triple bonds |
|
|
resonance |
Bonding in molecules or ions that cannot be correctly represented by a single lewis structure |
|
|
Ionic compound |
Composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal |
|
|
Formula unit |
The simplest collection of atoms from which an ionic compounds formula can be established |
|
|
Lattice energy |
The energy released when one mole of an ionic crystalline compound is formed from gaseous ion |
|
|
polyatomic ion |
Charged group of covalently bonded atoms |
|
|
Metallic bonding |
Chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons |
|
|
Malleability |
Ability of a substance to be hammered or beaten into this sheets |
|
|
Ductility |
Ability of a substance to be drawn pulled or extruded through a small opening to produce a wire |
|
|
VSEPR theory |
States that the repulsion between sets of valence electrons surrounding an atom causes these sets to be oriented as far apart possible |
|
|
Hybridization |
Mixing of two or more atomic orbitals of similar energies on the same Atom to reduce new hybrid atomic orbitals of equal energies |
|
|
Hybrid orbitals |
orbitals of equal energy produced by the combination of two or more orbitals on the same atom |
|
|
dipole |
created by equal but opposite charges that are separated by a short distance |
|
|
Hydrogen bonding |
Intermolecular force a hydrogen that bonded to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule |
|
|
London dispersion forces |
Intermolecular attractions resulting from the constant motions of electrons in the creation of instantaneous dipoles |
