In simple terms just by looking at them, and doing an electrical conductivity test you can tell the following.
the metals are shiny and conduct electricity. The non-metals which are gases or liquids are easy to distinguish. The solid non metals such as sulfur are not shiny and do not conduct electricity. (graphite conducts electricity but is soft and not that shiny). The metalloids look a bit like metals but are very poor conductors of electricity.
Examples of non-metal elements that are gases include hydrogen, oxygen, and many others, while bromine is the only liquid non-metal element.
Nonmetal. Nitrogen is a gas.
