Physical Properties: The physical properties of the meers change gradually as the nuer of carbon atoms per molecule increases. For example, the boiling points of the alkanes increase down the series, so that the first four meers are gases at room temperature and standard pressure; meers with five to seventeen carbon atoms per molecule are volatile liquids; while the higher meers are
Properties of Electrons - CliffsNotes
The Bohr model of the atom, in which electrons orbit about the nucleus, is a convenient representation. Unfortunately, it is not accurate. The results of scientific experiments suggest that electrons act more like electromagnetic waves than orbiting particles.
