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.
However, any State can opt out of Daylight Saving Time by passing a State law. Hawaii does not observe Daylight Saving Time and neither does Arizona (although the Navajo Nation, in northeastern Arizona, does).For many years, most of Indiana did not observe Daylight Saving Time with the exception of 10 counties. Beginning in 2006, all of Indiana now observes Daylight Saving Time.However, the state remains divided in two time zones. Seventy-four counties (including state capital Indianapolis) are in the Eastern Time Zone.or many years, most of Indiana did not observe Daylight Saving Time with the exception of 10 counties.
