Physical properties of hydrogen
♤colourless
♧odourless
♡tasteless
♧lighter then other gases
☆insoluble in Water (solubility 2% in water)
♢ difficult to liquefied.(At -200°c and at under high pressure (200atm)then it liquefied and there also it colourless .
♧some metals like platinum and palladium etc.adsorb hydrogen at high temperatures.
this phenomenon is known as occlusion of hydrogen .
♤bond length : 74.2 pm and bond energy is 436 know mole-1
