Gibson 1 Reagan Gibson Tripp Sanders Chemistry 1 May 2016 Introduction A Chemy Called Al is quite an interesting read. It is written by Wendy Isbell. It tells the story of a girl named Julie. The book begins talking about Julie and her electrical issues. It talks about her power being out but the TV still being on. It had to do with X-Ray Machines around the whole country. Well she goes to the land of Mathematics, she is afraid her friends are in danger- so she decides to go find them.…

Task-5 a) • Metals Metal structure is made up of crystals of metals which are made up of positive metal ions and these ions are surrounded by a sea of delocalized electrons. To separate these substances from this crystal lattice a lot of energy is needed. In between the positive and negative ions is present a strong electrostatic force of attraction. That is the reason why metals have strong melting and boiling points. In order to slide one layer of the metal ions over the other layer very less…

Today midian wants to give you a reason to read and to show science is not boring so please read. this 4 paragraph paper about molecules and what are they?They are cool genes we wear and they are cool to show off so sit back enjoy and thank you. 1# The first molecule is carbohydrates it's kinda of a sugar molecule the carbohydrates let your body talk to each other to keep you going. It's basically seen in sugar and they are made of a tiny little other substance called atoms. one sugar…

That being said I wanted to learn more about silicon and what people are putting in their bodies. Silicon is an element a pure substance that can’t be broken down. Silicon was first discovered in 1824 by a Swedish chemist named Jons Jacob Berzelius. This element is the second most abundant and it makes up about 27.7% of the earth’s crust. Although silicon is the second most abundant element, and it can’t be found free in nature. Silicon is usually found as silica or silicates. In order to…

Introduction Lead (Pb) contamination is a pervasive issue in many low-income neighborhoods throughout the United States. The toxicity of lead poses significant risks to human health, and proves to be especially harmful for children in terms of cognitive and physical development. Lead in the environment is primarily related to a legacy of anthropogenic sources including leaded gasoline, leaded paint, and various industrial applications. Although the presence of heavy metals is ubiquitous in the…

Why There Are No Pure Elements From Group 1 & 7 Group 1 elements are alkali metals which are very soft and reacts with metals well. The elements reacts very strongly with water. As you down the elements of group one, the reactivity increases. However, group 7 are halogens which are reactive, but they are metal. They are also different from group one as their reactivity decreases as you go down. Also, the elements becomes darker as you go down the group. Chemical reactions of group 1: The…

Utilizing our comprehension of the arrangement of the elements in the periodic table (the way elements with common traits are grouped together), we will determine the name and location of each unknown element by clustering said elements with other known elements that they share the most characteristics with. In this lab we will momentarily fill the shoes of the Russian chemist Dmitri Mendeleev, who was the first to observe the patterns between elements arranged according to their properties. His…

My chemical element is Sulfur. If you were to be looking at a periodic table, its symbol would be S. Sulfur’s atomic number is 16. Sulfur has 16 protons, 16 electrons, and 16 neutrons. Sulfur’s atomic mass is 32.065 and its mass number is 32. Sulfur comes from the Sanskrit word “Sulvere” and also the latin word “Sulphurium”. Sulfur was discovered in Ancient times and has been mentioned in both the Bible and the Torah. Sulfur is commonly found in meteorites, volcanoes, hot springs, and as…

Lead has been around for thousands of years, used with various products, and is a deadly element. Lead is found in all parts of Earth’s crust and has been used in products of various items in our homes, such as paint, pipes, batteries and even cosmetics (“Lead poisoning….” 2017). Humans have learned that lead is highly dangerous once inside our bodies, shutting down organs and beginning a wide collection of symptoms from lead poisoning. It is released into the environment through industrial…
