Graphite is an interesting material, an allotrope of carbon (as is diamond). It displays properties of both metals, and nonmetals. However, like a metal, graphite is a very good conductor of electricity due to the mobility of the electrons in its outer valence shells.
Arizona, Hawaii, American Samoa, Puerto Rico and the Virgin Islands donât participate in daylight saving. Indiana used to be split, but opted for daylight saving in 2005.
how many states dont change their clocks for daylight savings time and who. Arizona (with the exemption of the Navajo Nation) and Hawaii are the only states in the U.S. that do not observe Daylight Saving Time however instead stay on standard time all year long. The federal law that founded daylight time in the United States does not require any area to observe daylight saving time. But if a state decides to observe DST, it must follow the starting and ending dates set by the law.
