Chemical Formula: symbolic representative of substances.
Binary Compound: compound consisting of two different atoms/elements.
Tertiary Compound: compound consisting of two of more different elements usually an atom or an ion+ or radicals.
Ion: is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge.
Stock System: uses Roman numerals to indicate the oxidation number of the metal used enclose in parentheses.
Acids: compounds that produce hydrogen ions (H+) when dissolves in water.
Oxygen acids: acid containing H,O and another element.
Bases: compounds that yield hydroxide ions (OH-) when dissolved in water.
Chemical Reactions: Produces at least new substance.
Reactants: substances that reacts on a chemical reaction.
Products: substances that produce when chemical reaction is finished.
Chemical Equation: is a symbolic representation of a chemical reaction.
Exothermic Reaction: the release of heat energy from the system to its surrounding.
Endothermic Reaction: the absorption of heat energy from its surrounding to the system.
Chemical Bond: attraction between atoms that allows the formation of chemical substances that contain two or more atoms.
Valence Electron: electrons of an atom that can participate in the formation of chemical bonds with other atoms.
Ionic Compound: metal and nonmetal.
Hydrogen Bond: type of weak bond that uses H atom.
Molecular Compound: Nonmetal and nonmetal.
Octet Rule: is a chemical rule of thumb that states that atoms of low (<20) atomic number tend to combine in such a way that they each have eight electrons in their valence shells, giving them the same electronic configuration as a noble gas.
I U P A C: International Union of Pure and Applied Chemistry.
