Chapter 6 Flashcards
A mutual electrical attraction between the nuclei and valance electrons of different atoms that binds the atoms together
Chemical Bond
Chemical bonding that results from the electrical attraction between cations and anions
Ionic Bonding
Results from the sharing of electron pairs between two atoms
Covalent Bonding
A covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge.
Nonpolar-covalent bond
Having an uneven distribution of charge
Polar
A neutral group of atoms that are held together by covalent bonds
Molecule
A chemical compound whose simplest units are molecules
Molecular compound
Indicates the relative numbers of atoms of each kind in a chemical compound by using atomic symbols and numerical subscripts
Chemical Formula
Shows the types and numbers of atoms combined in a single molecule of a molecular compound
Molecular Formula
A molecule containing only two atoms
Diatomic molecule
The energy required to break a chemical bond and form neutral isolated atoms
Bond Energy
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
Electron-dot Notation
Formulas 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 unshared electrons.
Lewis Structures
Indicates the kind, number, arrangement, and bonds but not the unshared pairs of the atoms in a molecule
Structural Formula
A covalent bond in which one pair of electrons is shared between two atoms
Single Bond
Double and triple bonds are referred to as…
Multiple Bonds
Refers to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure
Resonance
Composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal
Ionic Compound
The simplest collection of atoms from which an ionic compound’s formula can be established
Formula Unit
The energy released when one mole of an ionic crystalline compound is formed from gaseous ions
Lattice energy
A charged group of covalently bonded atoms
Polyatomic Ion
The chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons
Metallic Bonding
The ability of a substance to be hammered or beaten into thin sheets
Malleability
The ability of a substance to be drawn, pulled, or extruded through a small opening to produce a wire
Ductility
