... Metals are “shiny“ solids that conduct electric current (very low resistance); they also conduct heat very well. Nonmetallic solids tend not to conduct electric current (exception: carbon as graphite). Many nonmetals are gases (of course gases do not conduct electric current). The elements very clos ...
