Essay on The Chemistry of Singual Atomized Materials

Some of the amazing qualities of these materials are that neptune balls don’t catch on fire, and spider silk can be used to make stuff like bandages, fishing line, clothes, rugs, blankets, and many more.

The first completed steel bridge was the Eads Bridge, in St. Louis Missouri. Steel was a very new material and was just starting to become commercially available. Steel was a smart choice to use because it is extremely hard and resists rusting. The Eads Bridge was the longest arch bridge in the world, of 510 feet long. St. Louis became a very important city in the midwest and had to really compete with Chicago during the Civil War. After the Civil War, St. Louis started growing in all directions. “.... the city of St. Louis wanted to reestablish its prewar dominance as the economic powerhouse of the midwest” (Ostrow 75). The main reason to build the Eads Bridge was to connect settlers from the East to the lands of the West. At the time there

The Steel’s physical properties include a stiffness level similar to mild steel. With the addition of chrome and molybdenum the steel can be strong enough to butt or be thinned down in the middle, thus making the material lighter.

Society relies heavily on metals in nearly every aspect of life; however the corrosion of such metals has become a costly and very prevalent issue worldwide. Large amounts of energy, time and money has been poured into

Bolted steel construction: this is when the main bulk of the construction is pre made at the workshop then bolted into place on site. This tends to be the preferred methods as it saves time and money as well having the right working conditions.

Lightweight construction has been used in building construction for more than thirty-five years. Fire fighters have been dealing with the dangers of this type of construction since it was developed. Lightweight construction is generally considered to be either wood frame or steel building materials, where the roof and/or floor supporting systems are constructed of lightweight prefabricated materials. The main problem with lightweight construction is the decreased load carrying capability and stability of the manufactured members under fire conditions.

Every year there is 1.3 billion tons of steel produced around the world. Steel is made in different sizes and categorized by how good the steel is, these is called grades and standards. Steel today is used in many things you wouldn’t even think of such as the armored vests policemen wear or jewelry. Stainless steel was invented in 1913 by Harry Brearley when he put 12.8% chromium and .24% carbon when the standard for steel was .12 - 2% carbon and 16 - 26% chromium. Stainless steel is used in almost all new home appliances and in Great Britain it was used for cars. Some buildings made with steel are the Chrysler building, the Empire State Building, and the Sears Tower. Another building made with tons of steel is the Burj Khalifa. It used 55,000 tons of steel to be made and at 2,717 feet it is the tallest building in the

It is silkworms that naturally create silk, however, the Chinese people invented how to harvest the silk and use it in clothing and paper thousands of years ago. The oldest silk, which was found in Henan Province, came from the chinese Neolithic period and dates to around 3,630 BC. Silk excavated from the Liangzhu Province date to roughly 2,570 BC. In ancient China, silk was not only a vital invention for life but also a bridge connecting China to the outside world.

During ancient Greece, Athena was considered to be one of the most powerful and influential gods of that time. The Greek goddess Athena is the goddess of war and wisdom, she is the balance between intellect and power. Ancient Greek civilizations shaped their gods into the images that they felt could portray their desired identity; to the Greeks Athena embodied everything they sought to have, wisdom, power, and the need for justice. To this day Athena is still regarded as the symbol for wisdom. In the 21st century the mark that Athena left over 2000 years ago is still very much relevant.

Upfront concrete is the cheaper option which sounds good for the people paying for it, but in the long run steel is more economical. Steel bridges are re-buildable, damage to a steel bridge is more noticeable, it takes a shorter time to build a steel bridge and Steel is more durable than concrete. All signs point to steel being the best choice for a bridge to be as effective as possible. “Steel spans last longer than concrete ones. Those built by eight mostly European firms under the PBP are rated for 80-100 years”

Many metals used in the United States has made huge impact on the environment and the societies. Iron has made a huge impact in the United States since it is one of the most common metal on Earth. Steel, an alloy of iron which has helped make automobiles, ships, railroads, building tools, kitchen appliances, utensils, and weapons. These items have impacted and helped improve on transportations, building equipments, kitchens, and wars. By improving transportation people got from one place to another faster. Kitchen appliances and utensils helped by improving the way you cooking and the way you eat. In the wars they used weapons such as, swords, guns, and armor wear. Steel can also make skyscrapers and pipes. By doing this America has rapidly

In the nucleus of an atom there are protons and neutrons the number of protons and neutrons depends on the element and ,if it is an isotope of that element. E.g. carbon 12, carbon 12 has six neutrons six protons and 6 electrons . Electrons are located around the nucleus of the atom. Electrons are in shells, the shell closest to the nucleus is 1 , the one after 2 and so on. Each shell can only hold up to a certain number of electrons . the first can hold up to 2 , the second 8 (2+6) the third up to 18 (2+6+10). The general formula for finding out how many electrons a shell can hold is 2n^2. Electrons have a negative charge , while protons have a positive and neutrons have no charge. A atom has the same number of protons and electrons. An ion is formed when an atom loses or gains a electrons .

As for metal, it has many uses. In fact, modern civilization has thrived off of things where iron is used like: buildings, car frames, bridges, and much more.

The following section will be describing the atom and all of the particles that make it up. It will start off with what protons, neutrons, and electrons are. This will describe where they are in the atom and what their relative sizes respective one another are. This section will end off with the charges of all of these particles and the total number of all of these particles for every element inside of the carbon family. The entire section will be based off of the particles that make up an atom and more details about them such as their location.

All spiders spin silk, though not all of them weave webs. Silk is most commonly seen used in forming webs, which may vary from a highly elaborated orb of spiraling threads to a single sticky string. Most webs can be placed into one of four different types: the orb webs, the funnel webs, tangle webs, and the sheet webs. The main purpose of a web
