With the exception of helium, the noble gases condense to form solids when they are cooled sufficiently. At temperatures below 83 K, argon forms a close-packed solid whose structure is shown below. (c) Based on this comparison would you say that the atoms are held together by chemical bonds in solid argon?

Hi everyone here we have a question telling us that diamond is a mineral made up of carbon atoms arranged in a crystal structure known as diamond cubic. The molecular representation of diamond and the distance between each carbon are shown below. If the estimated atomic radius of the carbon atom is 60 PICO meters are the carbon atoms in a diamond held together by chemical bonds. So our bonding radius, as we can see in our picture is 154 PICO meters and our estimated atomic radius is given to us in the prompt And is 76 PICO meters. So the estimated bonding radius for a chemical bond Would be 76 times two, Which equals 152. And because our bonding radius is so close to the estimated bonding radius, we can say that yes, it is held together by chemical bonds and that is our final answer. Thank you for watching. Bye.
