Physical properties:-Melting Point:101.5°C-Boiling Point:34.6°C-Classification:Halogen/non-metal-Density:3.214g/cm3-Colour:Greenish-yellow-State at room temperature:Gas-Viscosity:Low

Chemical Properties:-Chlorine is very reactive, and some other materials will easily burn (combust) when placed in chlorine.-For example, when thin pieces of copper are placed in chlorine, the copper reacts with chlorine to produce fine copper chloride particles, seen as dense smoke.
