BeauPure metal crystals have a regular and repeating atomic arrangement, known as a close-packed structure. They exhibit high thermal and electrical conductivity due to the free movement of electrons within the crystal lattice. Pure metal crystals are malleable, ductile, and have high melting points.

Why covalent crystals r opaque?
Covalent crystals are not necessarily opaque. Think of diamond, pure quartz crystals, pure aluminium oxide crystals these all are colorless and transparent.
Is beryllium a pure substance?
Yes, beryllium is a pure substance as it is a chemical element with the atomic number 4 and only contains beryllium atoms. It is a metal that exists in the form of solid crystals.
How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
What is the appearance of pure sulfanilamide after crystalization?
