Transition metals are a group of metals considered dense and have high melting and boiling points. They are found between the alkaline earth metal group and the boron group. Transition metals are characterized by the number of internal energy levels occupied by the atoms. They are then separated into 2 groups: f-type transition metals. D-type transition metals consist mainly of (commercially) important metals and rare, unimportant metals. They vary from very responsive to noble. The metals in this group all form a variety of different alloys. F-type transition metals consist of lanthanides (rare earth metals) and actinides ranging from thorium to lawrentium. These metals are very reactive. Only some of these elements are common, but many 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 found in period 11 group 6. It has the atomic number 79 and the atomic symbol of Au, which stands for the Latin word Aurum. Like all other transition metals, gold has a high melting and boiling point. Its melting point is 1.063℃ and its boiling point is 2.966℃. Furthermore, gold is the most malleable and most ductile of all elements. It is also an excellent conductor of electricity and heat. It also has high corrosion resistance. Gold is commonly alloyed with other metals for jewelry. For centuries it has also been used as money. Since gold is non-toxic, it is often used in medicine and dentistry. Gold is mined in two ways; placer and vein extraction. Deposit mining is when the metal is found in sand and soil… in the middle of paper… hey, they don't have to worry so much about gold plant rust. Gold, as mentioned, has a high melting point, which can come in handy because you don't have to worry about the gold implant melting in their eyes. Gold has a high density, which means there is more mass to help the eyelid close after implantation. Gold is also inert, meaning that gold does not react with other elements or substances. This can be helpful because there can be many different substances in the eye and if gold reacts with it, it can cause harm rather than help. Gold is also used in lagophthalmos implants because it is considered low cost. Although gold is quite expensive on the market, it is not the most expensive when compared to other transition metals. Platinum is more expensive than gold, making it a preferred choice over platinum.
