In addition, the binary hydrides of the elements of Groups 14–16 are gases. Because of their lack of reactivity, for many years they were called inert gases or rare gases. Define Pressure And Give The Common Units For Pressure. Examples at standard conditions include the noble gases argon, krypton, and xenon, though all chemical elements will be monatomic in the gas phase at sufficiently high temperatures. “Adish Aluminium”, is engaged in offering services for installation of Aluminum Doors, Windows and Partitions needs of our esteemed clients.
