Section 1

(29 cards)

molecule

Front

two or more atoms held together by covalent bonds

Back

chemical bond

Front

the attractive force that holds atoms or ions together

Back

bond energy

Front

the energy required to break a chemical bond and form neutral isolated atoms

Back

ionic bonding

Front

The electrostatic attraction between oppositely charged ions

Back

ductility

Front

the ability of a substance to be pulled into a wire

Back

salt

Front

An ionic compound made from the neutralization of an acid with a base.

Back

polar covalent bond

Front

unequal sharing of electrons

Back

triple bond

Front

a covalent bond in which two atoms share three pairs of electrons

Back

polar

Front

describes a molecule in which the positive and negative charges are separated

Back

London dispersion forces

Front

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

Back

oxidation state

Front

the condition of an atom expressed by the number of electrons that the atom needs to reach its elemental form

Back

formula unit

Front

the lowest whole-number ratio of ions in an ionic compound

Back

covalent bond

Front

a bond formed when atoms share one or more pairs of electrons

Back

malleability

Front

the ability of a substance to be hammered or beaten into thin sheets

Back

chemical nomenclature

Front

the systematic naming of chemical compounds

Back

van der Waals forces

Front

the two weakest intermolecular attractions- dispersion interactions and dipole forces

Back

nonpolar covalent

Front

equal sharing of electrons

Back

metallic bonding

Front

positively charged metallic ions are surrounded by a cloud of electrons

Back

molecular formula

Front

shows the types and numbers of atoms combined in a single molecule of a molecular compound

Back

polyatomic ion

Front

A charged group of covalently bonded atoms

Back

binary compound

Front

a compound composed of two elements

Back

double bond

Front

A covalent bond in which two pairs of electrons are shared between two atoms

Back

hydrogen bonding

Front

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

Back

dipole-dipole forces

Front

attractions between oppositely charged regions of polar molecules

Back

VSEPR theory

Front

Valence-shell electron-pair repulsion theory; because electron pairs repel, molecules adjust their shapes so that valence electron pairs are as far apart as possible

Back

Lewis structure

Front

A model that uses electron-dot structures to show how electrons are arranged in molecules. Pairs of dots or lines represent bonding pairs.

Back

oxidation number

Front

Positive or negative number that indicates how many electrons an atom has gained, lost, or shared to become stable

Back

dipole

Front

a molecule that has two poles, or regions, with opposite charges

Back

monatomic ion

Front

an ion formed from a single atom

Back
