The solution of sodium chloride in water is a good conductor of electricity because of the ions that act as the charge carriers. This difference in electronegativity forms a crystalline solid structure of positively charged sodium ions and negatively charged chloride ions.

In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.

In solids, the free electrons present in conduction band usually contribute for electrical conductivity. However, the sodium chloride in its solid state do not contain free electrons in its conduction band. Consequently, sodium chloride exhibits poor electrical conductivity in solid state.

Diamond is not considered as a non-metal in the exceptional category as diamond is a form of carbon. It is not classified as an element. Diamonds normally have high refractive index thus providing a brilliant shine to the diamond. It is an allotrope of carbon.

Diamond is not metal, it made of carbon. And diamond can not conduct electricity, it is not malleable and ductile, so, it’s not metal.

You see, iodine is a non-metal, has dark-gray texture. It is evident through different discoveries that iodine is a lustrous non-metal. On the other hand, Diamond has a very bright lustre, so much that it has the highest non-metallic lustre.

Diamonds do not emit toxically or release toxic substances. So if you lick a Diamond Mine and lick an accident victim or have your diamond in a poison before you have a taste of the diamond. Since diamond is the hardest stone, it is not easy to break it.

Diamonds are not particularly rare. In fact, compared to other gemstones, they’re the most common precious stone found. Generally, the cost per carat (or weight of a gemstone) is based upon a stone’s rarity; the rarer the stone, the more expensive.

Are diamonds poisonous? can I die if I lick pure diamond? no, as in times gone by people would lick diamond to check whether or not they were genuine, a real diamond’s (as opposed to a piece of glass or other rock) surface acts much like oil and does not get wet.

Is diamond powder safe to use? According to the Environmental Working Group’s Skin Deep database, diamond powder is safe for topical use. At least according to the research available, diamond powder doesn’t pose a risk of organ toxicity, endocrine disruption, cancer, or bio-accumulation.

Similar to graphite, diamonds are comprised purely of carbon. The carbon atoms in diamonds are organized as a rigid lattice, allowing less possibility of contamination and awarding it the title of the hardest known natural material.

Diamond Powder is a crystallized modification of carbon. DIAMOND and DIAMOND POWDER.

When writing the grades of a diamond using the AGS Scale, diamond Cut grade is first, then diamond Color, Clarity, then Carat Weight—in that order. If a diamond possessing the finest diamond Cut grade is also colorless, free of inclusions and blemishes, and weighs one carat, it would be written as: 0/0/0–1.000 carat.

DIAMOND SHAPE: PRINCESS This stone shape is for the woman who is drawn to the excitement and a true romantic at heart because the princess stone shape is known to manifest beauty, style, and edge. Truly the “hopeless romantic” of all shapes, some refer to this shape as the square diamond.
