DOUBLE DIN CAR STEREO EXAMPLE. When talking bout DIN car stereo, DIN refers to a standardized radio/stereo size for vehicles (large enough to accept a CD). The size is 2â³ high by 7â³ wide. 2 DIN or double DIN refers to units that are twice as high as the standard DIN, and so 1 DIN would be the standard DIN specification.
The noble gases are the elements in Group 18 of the periodic table. These are the inert gases, and they include helium, neon, argon, krypton, xenon and radon. The chemical sym â¦ bols for these elements are He, Ne, Ar, Kr, Xe, and Ra, respectively. 5 people found this useful.
The only chemical elements which are stable single atom molecules at standard temperature and pressure (STP), are the noble gases. These are helium, neon, argon, krypton, xenon and radon. The heavier noble gases can form chemical compounds, but the lighter ones are non-reactive or inert. For example, helium, being the simplest noble gas, has only two electrons, thus meaning it is satisfied with a complete outer shell, making it relatively non-reactive, hence it is a noble gas.
