Chemistry Semester 2 Study Guide-Terms
an ionic compound whose aqueos solution conducts an electric current.
the simplest ratio of ions represented in an ionic compound.
a solution in which the solvent is water.
a statement using chemical formulas to describe the identities and relative amounts of the reactants and products involved in the chemical reaction.
the process by which the atoms of one or more substances are rearranged to form different substances.
in a chemical equation, the number written in front of react or product tells the smallest number of particles of the substance involved in the reaction.
a chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the compounds.
Coplete ionic equation
an ionic equation that shows all the particles in a solution as they realistically exist.
a chemical reaction that occurs when a single compound breads down into two or more elements or new compounds.
a chemical reaction that involves the exchange of positive ions into two or more elements or new compounds.
the elctrostatic force that holds oppositely charge particles together in an ionic compound.
a mixture of elements that has metallic properties.
an ion that has a negative charge.
an ion that has a positive charge.
the force that holds two atoms together and formces an attraction of a positive ion for a negative ion or by the attraction of positive nucleus for negative electrons.
an ion formed from only one atom.
the positive or negative charge of a monatomic ion.
a polyatomic ion composed of an element, usually a nonmetal, bonded to one or more oxygen atom.
an ion made up of two or more atoms bonded together that acts as a single unit with a net charge.
a solid produced during a chemical reaction in a solution.
a substance formed during a chemical reaction.
a chemical reaction that occurs when the atoms of one element replace the atoms of another element in a compound.
a single coalent bond that’s formed when an electron pair is shared by the direct overlap of bonding orbitals.
Polar covalent bond
a type of bond that’s formed when electrons are not shared equally.
condition that occurs when more than one valid Lewis structure exists for the same molecule.
chemical reaction in which a greater amount of energy is required to break te existing bonds in the reactants than is released when the new bonds form in the product molecules.
chemical reaction in which two or more substances react to yield a single product.
a substance dissolved in solutions.
the substance that dissolves a salute to form solutions.
a molecular model that uses symbols and bonds to show relative positions of atoms.
forms when two or more atoms covalently bond and are lower in potential energy than its constituent’s atoms.
Valence Shell Electron Pair Repulsion model
Coordinate covalent bond
forms when one atom donates a pair electrons to be shared with an atom or ion that needs two elctrons to become stable.
process by which the valence electrons of an atom are rearranged to form four new identical orbitals.
any acid that contains hydrogen and an oxyanion.
indicates the relative ability of elements atoms to attract electrons in a chemical bond.
