Term | Definition |
Atomic structure | The atom is a basic unit of matter that consists of a dense, central nucleus surrounded by a cloud of negatively charged electron. |
Electron Structure | Way of accounting for the shape of an electron cloud. Indicates which orbitals are occupied. 2,8,8,8,8,8,8 etc... |
Bohr Rutherford diagrams | Diagrams middle: nucleus with # of positive molecules rings: Electrons (2,8,8,8,8,8,8 etc...) |
Binary Compound | Chemical compound composed of only two elements. |
Polyatomic Compound | A charged ion composed of two or more atoms covalently bonded. |
Covalent Bond | A chemical bond that involves sharing a pair of electrons between atoms in a molecule. |
Ion Formation | Ion formation is the gain or loss of electrons from the outer valence level of an atom so that it acquires a negative or positive charge the value of which is determined by the number of electrons gained or lost. |
Ionic Bonding | An ionic bond is a type of chemical bond that involves a metal and a nonmetal ion. |
Synthesis Reaction | A chemical reaction n which two or more reactants combine to produce a new product. A+B->AB |
Double Displacement | A chemical reaction in which the positive ions of two different compounds exchange places; results in the formation of two new compounds, one of which may be a precipitate. AB+CD->AD+CB |
Single Displacement | A chemical reaction in which one element takes the place of another element in a compound. A+BC->AC+B |
Decomposition | AB>A+B |
pH | A measure of hydrogen ion concentration. |
pH scale | A numerical scale ranging from 0 to 14 that is used to classify aqueous solutions as acidic, basic or neutral. 0-7 is acidic, 7-14 is basic. 7 is neutral. |
Acids | A compound that produces hydrogen ions, H+(aq), when dissolved in water |
Bases | A compound that forms hydroxide ions, OH-(aq), when dissolved in water. |
Neutralization | The reaction of an acid and a base to produce a salt and water. |
