Bonding
What is a bond between two atoms where electrons are shared between the atoms equally.
Endothermic Reaction
What is: a chemical reaction that takes in heat.
Enzyme
What is: a catalyst used by living things to speed up the rate of natural chemical reactions in the body.
What is: the SI unit for the amount of a substance.
Define Ionic Bonding
What is a bond between two atoms in which one atom steals electrons from another atom.
Exothermic Reaction
What is: a reaction that gives off heat.
Catalyst
What is: anything that is used to speed up a chemical reaction.
Define: Oxidation
What is: the process in which an atom loses electrons in a chemical reaction or loses a hydrogen atom and gains an oxygen atom in a chemical reaction
Define Metallic Bonding
What is a bond where positive metal ions form a lattice structure with freely moving electrons between them
Chemical Reaction
An interaction between two or more substances that interact to form two or more new molecules
Define: Reduction
What is: a reaction in which an electron is gained or an oxygen atom is lost and a hydrogen atom is gained.
Ion
What is: An atom or group of atom that has a positive or negative charge due to gaining or losing electrons.
Define Product
What is: the two or more molecules formed when two or more atoms or molecules react with one another.
Define: Redox Reaction
What is: a reaction that involves the transfer of atoms between two substances.
Define Reactant
What is: A substance that interacts with another reactant to form a product in a chemical reaction
Define: irreversible reaction
What is: a reaction that cannot be undone once it has occurred; the products can not react to form the reactants again.
