Homogeneous
|
Matter that is evenly distibuated throughout a volume
|
|
|
Element
|
Matter Which exibits definite physical and chemical prperties unique to itself and different from all other forms of matter and cannot be decomposed into simpler forms of matter.
|
|
|
Evaporation
|
The Transition of the surface molecules of a liquid into a gas, below boiling point
|
|
|
Nucleon
|
A particla that exists in the nucleus; protons and nuetrons
|
|
|
Isotope
|
Atoms of the same element that contain different numbers of nuetrons and therefore differ in atomic mass as well.
|
|
|
Artificial Transmutation
|
The bombardment of relatively stable nucleus with the end result of causing the nucleus to break into simpler fragments.
|
|
|
Kernal
|
The atom beneath the valance electrons, including the elctrons in the lower energy levels and the nucleus
|
|
|
Electronegativity
|
An atoms attraction to electrons in a chemical bond.
|
|
|
Diatomic Molecule
|
A nonmetal atom that forms one or more nonpolar covalant bonds with another atom of the same element to form a molecule consisting of the two atoms when there is no other element to bond with, Elements that so this are Br, I, N, Cl, H, O, F.
|
|
|
Molecule
|
A particle made of nonmetla stoms covalently bonded together to form a distinct and discrete particle.
|
|
|
Hydrogen Bond
|
The strong attractive force between polar molecules where one molecule contains H and the other molecule contains N, O or F. The H of one molecule attracts stongley to the N, O or F of the other molecule
|
|
|
Molecular Formula
|
The Actual number of nonmetal atoms in a molecule, a whole number multiple of the empirical formula.
|
|
|
Double Replacement
|
A solution reaction in which the positive ion of one compound combines with the negative ion of the other compound to form a precipitate, and the other ions remain dissolved in solution
|
|
|
Solubility
|
The maximum quantity of solute that can be dissolved in a given quantity of solvent at a given temperature to make a saturated solution.
|
|
|
Arrhenius Acid
|
An electrolyte that ionizes in aqueus solution to yield H+ as the only positive ion in a solution
|
|
|
Voltaic Cell
|
An electrochemical cell that produces electric current as a result of a spontaneus redox reaction, used to make batteries

|
Allotrope
|
A molecular form of an element
|
|
|
Saturated Hydrocarbon
|
A hydrocarbon with all single carbon-carbon bonds.
|
|
|
Isomer
|
Moleculeswith the same molecular formula, but with different structural formula.
