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.
At the top of the noble gases is little helium (He), with a shell that is full with only two electrons. The fact that their outer shells are full means they are quite happy and don't need to react with other elements. In fact, they rarely combine with other elements. That non-reactivity is why they are called inert. All of the elements in Group Zero are noble gases. The list includes helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). Don't think that, because these elements don't like to react, we don't use them. You will find noble gases all over our world.
