A  sample of iodine is easiest to ship as a powder because it is brittle, making it easy to break into small pieces. Helium is less dense than the elements that make up the air we breathe, so a balloon filled with helium will float in air. Plastic is a compound of non metallic elements, so its insulation properties make it popular coating for electric wires to prevent the current from escaping.
