Chemistry Chapter 6

Front 1

chemical bond

Back 1

mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together

Front 2

ionic bonding

Back 2

chemical bonding that results from the electrical attraction between cations and anions
[>1.7]

Front 3

covalent bonding

Back 3

the sharing of electron pairs between two atoms
[<0.3]

Front 4

polar-covalent bond

Back 4

covalent bond in which the bonded atoms have an unequal attraction for the shared electrons
[0.3 < X < 1.7]

Front 5

molecule

Back 5

a neutral group of atoms that are held together by covalent bonds

Front 6

molecular compound

Back 6

a chemical compound whose simplest units are molecules

Front 7

chemical formula

Back 7

indicates the relative numbers of atoms of each kind in a chemical compound using atomic symbols and numerical subscripts

Front 8

bond energy

Back 8

the energy required to break a chemical bond and form neutral isolated atoms,
expressed in kJ/mole

Front 9

structural formula

Back 9

indicates the kind, number, arrangement, and bonds but not the unshaerd pairs of the atoms in a molecule

Front 10

resonance

Back 10

refers to bonding in molecules or ions that cannot be correctly represented by a single Lewis structure

Front 11

ionic compound

Back 11

compound of positive and negative ions that are combined so that the numbers of positive and negative charges are equal

Front 12

formula unit

Back 12

the simplest collection of atoms from which an ionic compound's formula can be established

Front 13

lattice energy

Back 13

energy released when one mole of an ionic crystalline compound is formed from gaseous ions

Front 14

polyatomic ion

Back 14

a charged group of covalently bonded atoms

Front 15

metallic bonding

Back 15

the chemical bonding that results from the attraction between metal atoms and the surrounding sea of electrons

Front 16

malleability

Back 16

the ability of a substance to be hammered into thin sheets

Front 17

ductility

Back 17

the ability of a substance to be drawn, pulled, or extruded through a small opening to produce a wire

Front 18

VSEPR

Back 18

valence-shell, electron pair repulsion
states that repulsion between the sets of valence level electrons surrounding an atom causes these sets to be oriented as far away as possible

Front 19

hybridization

Back 19

the mixing of two or more atomic orbitals of similar energies on the same atom to produce new hybrid atomic orbitals of equal energies

Front 20

hybrid orbitals

Back 20

orbitals of equal energy produced by the combination of two or more orbitals on the same atom

Front 21

intermolecular forces

Back 21

forces of attraction between molecules

Front 22

dipole

Back 22

created by equal but opposite charges that are separated by a short distance

Front 23

hydrogen bonding

Back 23

the intermolecular force in which a hydrogen atom that is bonded to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule

Front 24

London dispersion forces

Back 24

the intermolecular attractions resulting from the constant motion of electrons and the creation of instantaneous dipoles
