Physical and chemical properties:
Every element in the periodic table has different physical and chemical properties. The physical features of an element are the features that can be seen without changing the element into another substance. Some physical properties include: colour, hardness, freezing point, melting and boiling point, density and luster. Aluminium is a very shiny metal with a silver-white colour with a blue tint. It is light weighted but a strong metal. It is a very soft metal making it very easy to shape. Aluminium has a hardness of 2.75. This means it is hard enough to scratch your fingernail but soft enough to be scratched by a penny. Each element has a unique density, density measures how solid an object is. Aluminium has a density of 2.7 grams per millilitre. This means that aluminium can still sink in water even though it has a light weight. Aluminium’s melting point is at 660.323°C an...

    Arsenic is element 33 on the periodic table and is in Group 15. Arsenic is obviously an extremely poisonous element; however, some people have found arsenic to have a restorative effect on them. Chemically, arsenic is a metalloid. Two common forms of arsenic are gray and yellow. (see Figure 1-A) Element 33 has an atomic weight of 74.9216 and the chemical symbol of As. It boils at 613ºC, melts at 817ºC, and has a density of 5.72. (see Figure 2-A) The element has been known for centuries and can be easily obtained from ores such as arsenopyrite (FeAsS), realgar (As2S2), orpiment (As2S3), and arsenic trioxide (As2O3). There are many uses for arsenic. Among them is in the manufacturing of glass to eliminate the air bubbles and the green color caused by contaminated iron compounds. Arsenic is also added to materials such as lead and copper alloys to increase the strength and better the corrosion resistance. Although it is well known that arsenic is often used in tales (both true and otherwise) as a killing agent, arsenic has been used as a curative as well. Before penicillin was introduced, arsenic played a significant role in the treatment of syphilis. Other good uses for element 33 are as insecticides and semiconductors. Gallium arsenide (GaAs) is a known semiconductor that is also used as a laser material. A good test for the detection of arsenic is the Marsh test, invented by James Marsh, an English chemist.

    A huge fascination of arsenic started in the 19th century when people got word of a province in southeastern Austria where people ate arsenic. Women would eat arsenic to help gain weight and fix their complexion to look more beautiful and men would eat arsenic because they believed it helped them breath easier when they were climbing high up in the mountains. One doctor by the name of Dr. Robert Craig MacLagan, was particularly interested in this and visited the town to see for himself what was really occurring. He observed the people and tested their urine to prove that they have been indeed ingesting arsenic. He wrote about the things he witnessed in the Edinburgh Medical Journal. The men in the town would eat 6 grains/dose at least twice a week, sometimes eating it on their bread or just drinking it with their water. As a result many Victorians began self-medicating themselves with arsenic.

    The alkaline earth metals are an interesting group of elements that have many properties and uses in this world. To learn about them will help one learn more about the world around them. These metals are soft, shiny, silvery, and very reactive; although they are not as reactive as the alkali metals, the group of elements right next to them. Speaking of groups, the alkaline earth metals are in the left side and in group 2 of the periodic table. When forming ions, the alkaline metals usually lose 2 electrons to get a positive 2 charge and become more stable. This allows them to take part in ionic bonds, mostly with the halogen family because halogens are negatively charged in their ionic form. Because the alkaline metals are positively charged, they attract and form ionic bonds.

    Aluminum is one of a number of soft metals that scientists call "poor" metals. It can be shaped and twisted into any form. It can be rolled into thick plates for armored tanks or into thin foil for chewing gum wrappers. It may be drawn into a wire or made into cans. Aluminum is a generally popular metal because it does not rust and it resists wear from weather and chemicals. (Bowman, 391) Aluminum is an element. Its atomic number is thirteen and its atomic weight is usually twenty-seven. Pure aluminum melts at 660.2ºC and boils at 2500ºC. Its density is 2.7 grams per cube centimeter. Aluminum is never found uncombined in nature. (Bowman, 391) Aluminum is a very useful metal that is light, easy to shape and can be strong. This makes aluminum one of the most used metals in the world, right behind iron and steel. (Geary, 185) In its pure state, aluminum is quite weak compared to the other metals. However, its strength can be greatly increased by adding small amounts of alloying elements, heat-treating, or cold working. Only a small percentage of aluminum is used in its pure form. It is made into such items as electrical conductors, jewelry, and decorative trim for alliances and cars. A combination of the three techniques has produced aluminum alloys that, pound for pound, are stronger than structural steel. Some common metals used in alloys for aluminum are copper, magnesium and zinc.(Walker, 31) The added elements give the aluminum strength and other properties. (Newmark, 41) Aluminum is one of the lightest metals. It weighs about 168.5 pounds per cubic foot, about a third as much as steel which weighs 487 pounds per cubic foot. (Neely, 214) As a result, aluminum has replaced steel for many uses. For example, some ...

    As for the valence electrons, they are simply electrons that are shared when atoms bond together. Moreover, you can find the number of valence electrons an element has just by looking at the periodic tables. The number of valence electrons is the same as the atom's group number which can be found by looking at its column. For example, carbon is in group 4; therefore, it has 4 valence electrons. The elements of the periodic table can be divided into three categories; metals, nonmetals, and metalloids. The periodic table is mostly elements that are metals which are good conductors of heat, however nonmetals are not good conductors of heat, and metalloids have properties of both metals and nonmetals. The elements in the periodic table are divided into groups. Group 1 are the "Alkali Metals" and they're the first column in the periodic table however, excluding Hydrogen. The Alkali metals are so soft and very reactive metals. In addition, Group 2 the " Alkaline Earth metals " are listed in the second column of the periodic

    Materialism is very complex, and can be defined on a number of different platforms. There is no one definite definition of materialism, meaning there is an ambiguity surrounding the construct of materialism. According to Kasser et al. (2004), consumers develop a materialistic value orientation at times when they experience feelings of insecurity, and from exposure to materialistic models and values. When the psychological needs of individuals are not met, they tend to move toward materialism in order to help them feel better about themselves, and reduce feelings of insecurity and self-doubt through the consumption of materialistic items.

    The recycling of aluminum saves 95 percent of the energy required to make aluminum cans for sodas as well as other liquids (Ackerman 6). The most recent investment in the paper industry has been in machines and mills designed specifically to handle recycled paper (Ackerman 7). In the United States alone, 67 percent of all steel production is from recycled and recovered steel. For the aluminum industry, 42 percent of all aluminum is recovered or recycled. Each aluminum can, contains about 55 percent recycled content. This is a leading economic success for community recycling projects all over the United States. That accounts for more than $1 billion in recycled aluminum cans (Ackerman 7). The value of materials recycled from solid waste has become a substantial amount. In 1996 this project had a dollar value of $3.6 billion and was projected to be $5.2 billion by 2005. Paper and paperboard were accounted for almost one-third of all recycled materials, in both 1996 and 2005 (Ackerman 8). The other two-thirds were made up of grass clippings, aluminum cans, glass bottles, steel, and other recyclable materials. In recycling these materials, the planet is being saved for the future generations to
