Appearance and Characteristics

Gallium chemical elements are classified as other metals. It was discovered by Paul E. Lecoq de Boisbaudran in 1875.

Prior to the discovery of gallium, Russian chemist Dmitri Mendeleev predicted its existence and key features. He predicted that the element would be under the aluminum of the periodic table, he named this imaginary element eka-aluminum.

French chemist Paul E. Lecoq de Boisbaudran discovered gallium in spectrometer in Paris in 1875

De Boisbaudran first extracted gallium from the zincblende ore in the Pyrenees and first gained 0.65 g from the 430 kg ore. He separates the gallium by electrolyzing the hydroxide in potassium hydroxide solution

Gallium is a soft glass of silver-colored glass. It is close to the nonmetal in the periodic table and its metallic properties are less noticeable than most other metals. Solid gallium is brittle and electrically conductive rather than lead.

Nut solid metal destruction (conchoidally means like shells - broken surfaces are curved like seashells)

Gallium is the second largest liquid range of all the elements and is one of the few metals in the liquid near room temperature (melting point 29.76 oC, 85.6 o F) melted in hand.

In some medical thermometers, low melting point gallium alloys are used as non-toxic substitutes for mercury

Gallium arsenide is used in semiconductor manufacturing and is mainly used for laser diodes, light emitting diodes and solar panels. It is also used to make beautiful mirrors

Source: Gallium does not exist in nature, it does not contain any minerals containing a lot of gallium. Commercially, most gallium is extracted as a by-product of the production of aluminum and zinc. Gallium is also extracted from coal soot

Isotope: Gallium has 24 isotopes with known half-lives of 61 to 84. Two of them are stable: 69 Ga and 71 Ga, 60.1% and 39.9% natural amount, respectively.

The terrain is great ancient, ancient and medieval, it has extensive literature. Since genetic defects are sometimes revealed by physical features (eg the upwardly inclined eyes and the characteristic appearance of Down's syndrome with a wide plane), some geomorphological elements evolve in physiology and biochemistry did. The second aspect - the fortune-telling from shape and character - is related to astrology and other forms of fortune-telling, and this aspect of the subject is even greater in medieval fancy literature. The earliest classical literature including Homer and Hippocrates has evidence that terrain is part of the oldest practical philosophy.

The earliest systematic paper on terrain was attributed to Aristotle. Among them, he is divided into six chapters to study research methods, general symbols of personality, special characteristics of personality, strength and weakness, genius and foolishness. He then examined the characteristics obtained from different features, colors, hair, body, limbs, walking and sound. For example, when discussing the nose, he said that the end of the thick bulb belonged to those who are numb and jealous; the sharp nose is violent like a dog, vulnerable, easy to cause, round, big and dull I caught my nose to an eagle, slimy, like a nose, a lion.

Basenji belongs to the Shaman family. In other words, it has the original appearance and features. A parrot-shaped dog is medium in size, has rough ears, a wedge-shaped head, a long tail, and the back is rounded. Coats are usually neutral, such as sunburn, brown, black, but there are things with patches or speckles. This is another varieties that is said to be traceable to Pharaoh and there is no evidence to support this claim. It is said that seeds drawn on the walls of ancient Egyptian tombs include dachshunds and pharaoh hounds. A dog that looks like a modern basenji must have existed for thousands of years, but the varieties we know today existed for more than a century.
