Question
This element forms an interesting allotrope called Buckminster fullerene. Which element is Buckminster fullerene composed of and how did this allotrope get its name? Many gemstones are composed of aluminum compounds. When this element is present in trace amounts in beryl or beryllium aluminum silicate it forms emeralds. When this element is present in corundum or aluminum oxide it forms rubies. What is this element? Which element is a solid at room temperature, but will melt when held in your hand (37 degree C)? This element was named after a chicken because it was discovered by Paul-Emile Lecoq. And has highest spread between MP and BP!Explanation / Answer
Q5)
The BUckminster fullerene is an allotorope of carbon.
It is named after Buckminster Fullerof U.S. who designed geodesic domes of the shape exactly that of fullerenes. They consist of balls/spheres containing six membered and five memebered rings.
Q6) Ruby is a variety of mineral corundum(aluminium oxide) whose red/pink colour is caused by the presence of element Chromium.
Q7) Gallium is the element that is solid at room temperature but melts when held in hand due to its low melting point of 37 C. It has quite high boiling point of about 2100C. The difference between melting and boiling points is very large for Ga metal.
the name Le-coq in latin means rooster, so its discoverer named the metal after himself.
