Lead (atomic number 82) and gold (atomic number 79) are defined as elements by the number of protons they possess. Changing the element requires changing the atomic (proton) number. ... Transmutation of lead into gold isn't just theoretically possible - it has been achieved..

Yes. It makes up the majority of the bullet (even in modern bullets). Most have some form of jacketing (copper) - but that is because the friction of the higher speed “modern” bullets would melt the lead inside the barrel. Lead is reasonably cheap, very dense, and is reasonably soft (as far as metals go).

Authentic gold watches are made of 18K real gold material, but some fake products are only using electroplating process, the color and the original version are no different, it can not be distinguished without the instrument.

You can question the authenticity about various aspects of Bering Sea Gold, but there is one thing that they show certainly does not misrepresent: people can make a serious living mining for gold in the Bering Sea. In fact, it can literally make people millionaires.

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

Explanation: The enthalpy of fusion (energy need to change state from solid to liquid) of lead is 4.77 kJ/mol (so it takes 4.77 kJ to melt one mole of lead). We need to find the number of moles ( n ) of lead in 1.5kg ( m ).

At some point cadmium became a popular replacement for lead in jewelry, likely due to an increase in lead restrictions. Cadmium is used to add mass and weight to jewelry and can add a shiny finish. Cadmium has a lower melting point than metals such as zinc, reducing the energy required to melt it into shape.

Gold has been used to make ornamental objects and jewelry for thousands of years. Gold nuggets found in a stream are very easy to work and were probably one of the first metals used by humans. Today, most of the gold that is newly mined or recycled is used in the manufacture of jewelry.

No, definately not. They sell gold plated chains. They chains are usually sterling silver but dipped in whatever karat gold.

Amongst metals, lead has the highest specific gravity, that is, it has the highest density in comparison to water at any specific temperature. This is closely followed by the metal gold when it comes to the specific gravity.

By itself gold is not attracted to the magnetic fields we come across in our everyday lives. If you have a massive magnetic field then gold will be ever so slightly magnetic. It's safe to say that for practical purposes gold is not magnetic.

Precious Metals Aren't Magnetic Gold, silver, and platinum are not magnetic. The next time you spot precious metal, put it to the test. Take your coin or piece of jewelry, and place a strong magnet on top of the object.

Yes. All white gold, is essentially an alloy of pure (24ct) yellow gold, so it is natural to assume that it has a yellow tinge. The rhodium plating is a process which gives the white gold its ultra white colour by placing a coating over the existing metal.

Electroplating is a process in which depositional of precious metal on non valuable metal is done..... so if we look on above line so we can conclude that a metal which seems to be like gold is not actually gold because it may be depositional of gold through process of electoplating.....

The higher the karat, the more pure gold is present. However, this also means that the higher the karat, the softer it becomes. ... While rose gold gets its pink tint from a mixture of pure gold and copper, yellow gold is often created by adding silver, copper, and zinc to gold.

Gold recycling from laptops: there's gold in them thar Dells! ... Electronics, however, has developed something of a gold habit. The precious metal is an excellent conductor; it doesn't tarnish or corrode like copper and silver, and so can be used in very thin layers to reliably conduct small currents.
