Summary of Chapter 4: Atoms and Elements
Atoms are incredibly small. A single pebble from the shoreline contains more atoms than you could ever count. The number of atoms in a single pebble far exceeds the number of pebbles on the bottom of San Francisco Bay. To get an idea of how small atoms are, imagine this: If every atom within a small pebble were the size of the pebble itself, the pebble would be larger than Mount Everest.

Key Chemistry Terms and definitions covered in this textbook
-
Absorbance (A)
A quantitative measure of the extent to which a compound absorbs radiation of a particular wavelength. A 5 log (I0/I ) where I0 is the incident radiation and I is the transmitted radiation
-
acetal
A functional group characterized by two alkoxy (OR) groups connected to the same carbon atom.Acetals can be used as protecting groups for aldehydes or ketones.
-
carbides.
Ionic compounds containing the C2 22 or C42 ion. (22.3)
-
Confi gurational isomers
Isomers that differ by the confi guration of substituents on an atom. Refers to the arrangement of atoms about a stereocenter
-
diamagnetic anisotropy
An effect that causes different regions of space to be characterized by different magnetic field strengths.
-
Enantiomeric excess (ee)
The difference between the percentage of two enantiomers in a mixture
-
haloform reaction
A reaction in which a methyl ketone is converted into a carboxylic acid upon treatment with excess base and excess halogen, followed by aqueous acid.

halogenation
A reaction that involves the addition of X2 (either Br2 or Cl2) across an alkene.
-
Heterocyclic amine
An amine in which nitrogen is one of the atoms of a ring
-
metal complex
An assembly of a metal ion and the Lewis bases bonded to it. (Section 23.2)
-
Molecular ion (M1)
The radical cation formed by removal of a single electron from a parent molecule in a mass spectrometer.
-
Molecular spectroscopy
The study of which frequencies of radiation are absorbed or emitted by a particular substance and the correlation of these frequencies with details of molecular structure.
-
nonionizing radiation
Radiation that does not have sufficient energy to remove an electron from a molecule. (Section 21.9)
-
Oil
When used in the context of fats and oils, a mixture of triglycerides that is liquid at room temperature
-
reaction mechanism
A detailed picture, or model, of how the reaction occurs; that is, the order in which bonds are broken and formed and the changes in relative positions of the atoms as the reaction proceeds. (Section 14.6)
-
resonance
A method that chemists use to deal with the inadequacy of bond-line drawings.
-
solvolysis
A substitution reaction in which the solvent functions as the nucleophile.
-
spin-spin splitting
A phenomenon observed most commonly for nonequivalent protons connected to adjacent carbon atoms, in which the multiplicity of each signal is affected by the other.
-
