At room temperature hydrogen is a gas. It is a colorless, tasteless and odorless gas. It is the lightest gas. It is insoluble in water. It is highly inflammable and burns with blue flame forming water. Liquefication temperature of hydrogen is -252oC. Bond energy of H-H is 431 Kj/mole. Electro negativity of hydrogen is 2.1.
The metal is very difficult to fabricate, but the powder can be sintered in a hydrogen atmosphere at a temperature of 2000Â°C. The solid metal is not affected by air at room temperature, but the powdered or spongy metal slowly gives off osmium tetroxide, which is a powerful oxidising agent and has a strong smell.
