(23 cards)
Cation
An ion with a positive charge
Anion
An ion with a negative charge
Ionic compound
A chemical compound formed by the transfer of electrons
Covalent compound
A chemical compound formed by the sharing of electrons between non-metal elements
Molecule
Two or more atoms held together by covalent bonds
Reactants
A starting material in a chemical reaction
Products
The elements or compounds produced by a chemical reaction.
Chemical reaction
The process by which one or more substances change to produce one or more different substances
Decomposition reaction
A chemical reaction that occurs when a single compound breaks down into two or more elements or new compounds
Single replacement reaction
A chemical reaction in which one element takes the place of another element in a compound
Double replacement reaction
A chemical reaction between two compounds where the positive ion of one compound is exchanged with the positive ion of another compound
Combustion Reaction
A chemical reaction that occurs when a substance reacts with oxygen to produce carbon dioxide and water
Combination reaction
A chemical reaction where two or more substances react to form one product
Precipitate
A solid that forms when two solutions are mixed
Collision theory
For a reaction to occur, the particles must collide, they must collide with the appropriate orientation, and they must collide with sufficient energy
Reaction rate
The rate at which reactants change into products over time
Chemical equation
A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products
Aqueous solution
Water that contains dissolved substances
Law of Conservation of Mass
Matter is not created nor destroyed in any chemical or physical change
Ionic formula
Gives the simplest whole number ratio of the ions which form an ionic compound
Ionic bond
A chemical bond resulting from the attraction between oppositely charged ions.
Polyatomic ion
An ion made of two or more atoms
Monoatomic ion
An ion formed from a single atom
