Flashcards in Chapter 3 Deck (29)
A negatively charged ion
A compound made from two elements
bonding electron pair
A pair of valence electrons that is shared by two atoms and that holds the atoms close to each other
A positively charged ion
An attractive force that holds atoms together in a chemical compound
A chemical compound that is formed by the sharing of two electrons between two atoms
a covalent bond in which four elections are shared between two atoms
A measure of the attraction of an element for electrons
An aotm or group of atoms in which the numbers of protons and electrons are different
A chemical compound that is made from ions
An electrically neutral group of atoms held together by covalent bonds
An ion that consists of a single charged atom
nonbonding electron pair
A pair of valence electrons that is not shared with another atom
nonpolar covalent bond
a covalent bond in which neither atom has an electrical charge
the tendency of atoms to have 8 valence electrons when they form molecules or ions.
polar covalent bond
a covalent bond in which the bonding electrons are shared unequally
an ion that contains more than one atom
rule of charge balance
the rule that any ionic compound have equal amounts of positive and negative charge.
A covalent bond in which two atoms share one pair of electrons
A covalent bond in which 6 electrons are shared between two atoms
The study of the mass-mole-number relationships of chemical formulas and reactions
A starting substance in a chemical reaction
A substance formed in a chemical reaction
A statement that uses chemical formulas to express the identities and quantities of the substances involved in a chemical or physical change.
A formula that shows the actual number of atoms, their relative placement, and the bonds between them.
A method for determining the formula of a compound from the amounts of its combustion products.
One of two or more compounds with the same molecular formula but different properties, often as a result of different arrangements of atoms
A chemical formula that shows the lowest relative number of atoms of each element in a compound
