Tin has two common allotropes at atmospheric pressure.Gray tin,or $\alpha$-tin,which is stable below 13.2 $\circ$ C,is a dull gray powdery material with essentially no electrical conductivity.White tin,or $\beta$-tin,which is stable at or above room temperature,is malleable,silvery-white,and conductive in three dimensions.Which of the following statements regarding these allotropes could be correct?

Question

Quizplus · Accepted Answer

Gray tin adopts a structure similar to diamond, which is a covalent network solid with a tetrahedral arrangement, explaining its lack of electrical conductivity.
