Lead chromate, PbCrO 4, is also used as a pigment under the name chrome yellow. A brilliant red-orange color is exhibited by the mineral crocoite, a mineral form of PbCrO 4. Lead in its metallic form is widely used for radiation shielding because of its high absorption constant for x-rays and gamma-rays.
Sodium is an alkali metal located in the first group or column of the periodic table. The sodium atom has 11 electrons and 11 protons with one valence electron in the outer shell. Characteristics and Properties Sodium in its pure form is very reactive.

A single buckyball consists of 60 or 70 carbon atoms (C 60 or C 70) linked together in a structure that looks like a soccer ball. They can trap other atoms within their framework, appear to be capable of withstanding great pressures and have magnetic and superconductive properties.
Lutetium, like other rare earth elements, does not occur in pure form in nature. Alchemist-hp, Creative Commons License Lutetium is a soft, silvery rare earth metal.
What does chlorine look like in its pure form – The Q&A wiki it is actually a greenish yellow color and you put it into a pool to purifie drinking water and to dissinfect a pool. it is used as an anitiseptic
Lead is the Eeyore of metals - slow, dull and heavy. In its Latin form, plumbum, it enters our vocabulary by virtue of its soft and ponderous character: we once plumbed depths with a suspended grey blob of the stuff, emphatically commanded by gravity, while plumbers have long since traded their malleable lead pipes for plastic. Everything ...
The hardness of pure lead is 1.5 on the Mohs scale (between talc and gypsum: it can be scratched by the fingernail), and its tensile strength is only 2000 psi. The Young's modulus is 2.56 x 10 6 psi. Its crystalline form is face-centered cubic, with lattice constant 0.4939 nm.
Hydrogen in its atomic form is found commonly in space and stars. There are vast clouds of hydrogen in outer space. However much of the hydrogen in space is missing an electron, which means it is an ion. On Earth, hydrogen is commonly found as part of water molecules. Many other molecules also contain hydrogen.
Pure iron is a bright silvery-white metal which oxidizes (rusts) rapidly in moist air or in water containing dissolved oxygen. It is soft, malleable, and ductile, and is strongly magnetic (ferromagnetic).It is rare to find it in elemental form on the Earth, but the sample at right was found in Greenland. It has also been found in igneous rocks in Russia.
Mercury occurs naturally in the environment and exists in a large number of forms. Like lead or cadmium, mercury is a constituent element of the earth, a heavy metal. In pure form, it is known alternatively as "elemental" or "metallic" mercury (also expressed as Hg(0) or Hg 0).
LSD looks like a clear, odorless and tasteless substance. The drug, in pure form is not easily spotted against any other substance. Because it has no taste, LSD is often liquidized with water or other solubles and then dripped onto candy, sugar cubes, blogger paper or gelatin.

Fine gold is usually sold to a refiner, who then melts it down and refines it into pure bullion form, to eventually be sold on the world gold market. ... But watch what the acid will do to nearly any base metal like lead: ... silver in its native form does not look like shiny silver-like in silverware. It looks more like a silver-colored rock ...
Feb 13, 2010· Best Answer: The dominant ore mineral is lead sulfice, also known as galena. Rock containing a lot of galena is blasted and collected and put into a crushing mill. The galena is separated by a combination of density (gravity) separation and chemical means (such as mineral flotation) to produce a "concentrate".
Lead shows oxidation states of +2 and +4 in its compounds. Among the many important lead compounds are the oxides: lead monoxide, PbO, in which lead is in the +2 state; lead dioxide, PbO 2, in which lead is in the +4 state; and trilead tetroxide, Pb 3 O 4. Lead monoxide exists in two modifications, litharge and massicot.
In welding industry, the welding torches that are used for melting steel consist of hydrogen. In chemical industry, it is used as a reducing agent for extraction of metals from their ores. For instance, tungsten which is mined in the form of tungsten oxide is treated with hydrogen to obtain pure tungsten and water.
What Does Raw Copper Look Like? In its raw form at standard temperature and pressure, copper is a red-orange solid metal. It is a ductile metal that is soft and malleable at room temperature. Copper is a chemical element that has an atomic symbol of Cu and an atomic number of 29. It has an atomic ...
Although iodine is a useful element that's necessary for human health, it is very dangerous in its pure form. When working with elemental iodine in either the solid crystal or vapor phase, safety precautions must be taken, as the solid, concentrated form is highly dangerous.
If you do that, then it's not in its pure form. I think it's impossible to tell what an invisible … gas looks like in its pure form. If you pass an electric current through helium then you will be able to see it.
Radium is present in all uranium metals, and can be extracted from the waste products of uranium processing. What does it look like? Radium, when in its pure metal form, is a brilliant white while fresh. However, it blackens when exposed to air, due to the formation of radium nitride on the surface.
However, exposure to oxygen at higher than normal pressures, e.g. scuba divers, can lead to convulsions. Ozone (O 3) is toxic and if inhaled can damage the lungs. Characteristics: Oxygen in its common form (O 2) is a colorless, odorless and tasteless diatomic gas.
The use of uranium in its natural oxide form dates back to at least the year 79 CE, ... which, like uranium-235, is also fissile by thermal neutrons. ... Very pure uranium is produced through the thermal decomposition of uranium halides on a hot filament.
As for its origin, the original melting company has no idea what it was used for originally and neither do I--massive chunks of pure chromium are pretty scant, the two main examples being electrolytically deposited anodes and sputter targets, of which this is neither.
When heated in air, arsenic combines with oxygen to form arsenic oxide (As 2 O 3 ). A blue flame is produced, and arsenic oxide can be identified by its distinctive garlic-like odor. Arsenic combines with oxygen more slowly at room temperatures.
Crystals do not form in lead unless it is reasonably pure. Reduction of oxides to their underlying metal is the most common way in which metals are extracted from ores. For example iron ore is iron oxide, and it too is reduced by heating with carbon (coke).
Carbon also occurs in the form of carbon dioxide (CO 2 ) in the atmosphere. Carbon dioxide makes up only a small part of the atmosphere (about 300 parts per million), but it is a crucial gas. Plants use carbon dioxide in the atmosphere in the process of photosynthesis.
Iodine is a non-metal. It's boiling point is 457 K (184 o C) and melting point is 386.6 K (113.5 o C). Iodine belongs to group 7A,the Halogens. Belongs to period 5 in the Periodic table. Iodine might be used in its pure form, but most of the times it is not used as a pure iodine.
