Transition metals are a group of metals that are considered dense and have high melting and boiling points. They are located between the alkaline earth metals group and the boron group. The transition metals are characterized by the number of inner energy levels that are occupied by the atoms. They are then separated into 2 groups: d-type transition metals and f-type transition metals. D-type transition metals are mostly consisted of important metals (commercially) and the rare and unimportant metals. They are ranged from very reactive to noble. The metals in this group all form a variety of different alloys. The f-type transition metals consists of lanthanides (rare earth metals) and actinides which is from thorium to lawrencium. These metals are very reactive. Only a few of these elements are common but several of the f-type elements are useful. For example, cerium and thorium, which are found in alloys, uranium and plutonium in nuclear reactors. Gold is a soft, malleable, yellow metal that is located in period 11 group 6. It has the atomic number of 79 and the atomic symbol of Au, which stands for the Latin word Aurum. Like all the other transition metals, gold has a high melting and boiling point. Its melting point is 1,063℃ and its boiling point is 2,966℃. Also, gold is the most malleable and the most ductile of all the elements. It is also an excellent conductor of electricity and heat. It also has a high resistance to corrosion. Gold is commonly alloyed with other metals for jewelry. It was also used as for currency for centuries. Because gold has a lack of toxicity, it is used in medicine often as well as dentistry. Gold is mined in two ways; placer and vein mining. Placer mining is when the metal is found in sand and g... ... middle of paper ... ...hey don’t have to worry as much about the gold implant rusting. Gold, like mentioned has a high melting point, which can come in handy because one does not have to worry about the gold implant melting in their eyes. Gold has a high density, which means that there is more mass to help the eyelid close after the implant. Gold is also inert, which means that that gold will not react with other elements or substances. This can be beneficial because in the eye, there can be many different substances, and if gold reacts with it, it can do harm rather than help. Gold is also used in the implants of lagophthalmos because it is considered to have a low cost. Although, out in the market, gold is quite expensive, it is not the most expensive when it is compared to other transition metals. Platinum is more expensive than gold, which makes it a preferred choice over platinum.
