Causes And Disadvantages Of Metals
without metal. The metals we use in our houses are mostly for keeping them sturdy. Though there is one problem we have when it comes to metals. That problem is that they rust. Metals rust when they are in contact with oxygen, and water. They rust much faster when they are in contact with salt water, and acid rain. We chose to see what would happen to various metals when they contacted with salt water. When the electrons move around in the salt water, it causes the metals to rust. The metals we chose were iron, copper, lead, zinc, and aluminum. Those are some of the most commonly used industrial metals. We got the salt water directly from the beach, so that we would get the same reaction if this happened in real life. The chemicals that are …show more content…
Rust is one of the main disadvantages. Metals can rust when they are revealed to moisture. Rust is produced by metal and oxygen from water in the air mixed together. Copper and bronze turn green when they rust.

Another disadvantage of metals is that some of them are very expensive.
Rhodium is one of the most valuable metals. The average price of a kilogram of ruthenium is $13,548 ($420 per troy ounce). You have to pay $500 per kilogram of indium. Indium is also the tenth most valuable metal in the world.

One of the metals for the experiment was zinc. Zinc oxide is a common zinc compound that forms when metallic zinc is exposed to air. Zinc also has many alloys. One of the many alloys zinc has is brass. Like zinc brass dose not rust. It slightly loses its color sometimes, but it can regain it by being washed.

The process of making zinc has a name. It is called Galvanization. Galvanization is when an object is put into corrosion, and is given a coating of molten zinc by dipping it into it. Galvanization is the process that turns other metals into zinc. A metal can be changed into zinc so it could be more efficient than what it already is. Zinc is one of the most common used construction metals. So Galvanization would be a good way to reuse

When copper is mixed with other metals it can create a certain metal. When copper is mixed with zinc it creates brass. This is called an alloy. Copper is known for its high thermal and electrical conductivity and resistance to corrosion. That is why most wires are made from copper. Copper is made up of CU on the periodic table of elements.

There is also a process to making copper. Some copper is found pure, but some is found mixed into other minerals. You can take the copper out by melting it. Some people think that metals cannot be melted. Although, just like gold, copper can be melted, and molded into different shapes, some metals have really high melting points. Coppers highest melting point is 1,981*F 1,083*C 1,356*K.

The third metal for the experiment was iron. Iron is the most common used industrial metal. Iron easily rusts. When it is being transported to a different location for construction, most of the time, it rusts on the way there. Some of the components in iron explain this. Iron consists of 5% of the earth's crust. Iron is made from FE on the periodic table of

    Brass: The two major metals in brass are copper and zinc. The proportion of the copper to zinc affects the colour of the alloy, ranging from a rose coloured alloy to a yellow alloy. The higher the proportion of zinc, the greater the hardness and tensile strength of the alloy. Brass can be highly polished and is lustrous which makes it useful for ornamental materials and musical instruments, it can be quite soft and malleable which makes it good for creating jewellery and alloyed in the right proportion, it can also be very hard which makes it good for creating bolts and nuts as well as machine parts.…

    Copper is the 29th element in the periodic table, located more specifically at group 11, period 4. Because of its chemical and physical attributes, it is a transition metal, which denotes high boiling and melting points. Both a conductor of heat and electricity, Copper is ductile and malleable. Its symbol “Cu” derives from the Latin cuprum. Copper is also valued for its two-for-one practicality: it is a vital nutrient that has antibacterial properties. Aside from what many people generally know about Copper (the “common knowledge,” so to speak), there is much information regarding its atomic buildup.…

    Copper is ductile, malleable, and a good conductor of heat and electricity. Since copper is a very good conductor of electricity, a lot of electrical wires are made out of copper. This helps easily transfer electricity. Electrons move candidly in copper because they are ready to bond with another atom to form an stable octet. An octet is eight valence electrons in the outer energy level. Having eight in the outer energy level will make the ion stable. Copper has a germicidal effect meaning that many germs are neutralized by it. This is why it is often used in things like doorknobs because of its automatic disinfecting qualities. This is also why copper was used in ancient days to treat wounds. (Hamilton, 2003-2008). Copper is also found in a lot household items. For example lightning rods, washer, dryer, televisions, cell phones, pipes, and even refrigerators. The only bad thing about having copper pipes in a house is that if that house gets struck with lightning the pipes could cause damage to the house. The element Copper was actually used to make the Statue of Liberty. Now all that is seen is a big green lady but really the copper reacted with the oxygen in the air. That process is called oxidation and that is why lady liberty is green. Fun fact, the amount of copper used on the Statue of Liberty could make 30 million pennies. (NCFL, 2014-2016). Copper is also very efficient and good for this earth. This is because…

    Copper is an element that can be found in nature in a variety of different compounds. The most common natural ore is the sulphide, known as chalcocite, Cu2S. This mineral is an important source of copper metal because it is about 80% copper by weight. Copper has many important uses due to its chemical and physical properties. Copper is a good conductor of both heat and electricity, hence it can be found in electrical lines or on cooking pots. It is also used in brass and bronze as an alloying…
