The shape of nonmetals cannot be changed easily because they are brittle and will break.Įlements that have properties of both metals and nonmetals are called metalloids. As compared to metals, they have low density and will melt at low temperatures. Their surface is dull and they don’t conduct heat and electricity. Nonmetals, on the right side of the periodic table, are very different from metals. Heat and electricity travel easily through metals, which is why it is not wise to stand next to a flagpole during a thunderstorm!

Metals will corrode, gradually wearing away, like rusting iron. Their shape can be easily changed into thin wires or sheets without breaking. They are usually shiny, very dense, and only melt at high temperatures. The periodic table on the left separates elements into three groups: the metals (green in the table), nonmetals (orange), and metalloids (blue). What's a molecule? Metals, Nonmetals, & Metalloids
