P2+-+Halogen

= = = Halogens = Group17,periods 2,3,4,5,6,7

Halogens are found in all states of matter. In the solid state halogens are found in Iodine and Astatine. In the liquid state halogens are found in only Bromine. It is also found in the gas state and that is fluorine and chlorine. Three physical properties are it is a gas, liquid, and solid. Chemical properties is that is has a low melting and boiling point. Which means they are at about room temperature.
 * Bromine- liquid
 * Florine- gas
 * Iodine- solid[[image:file:///Network/Servers/h-student2.inside/Volumes/H-Student2-Data/h-students2/stewartt/Desktop/halogens.jpg]]
 * Astatine- solid
 * Chlorine- gas

 Interesting facts!
