Periodic Table

Chemistry relates to everything we touch, see, smell, hear, and taste because atoms make up everything in the universe. Chemistry influences so much in our everyday lives that it is hard to think of an activity that does not involve a chemical process in some way. The science also plays a major role in the human body. Our bodies are made up of chemicals, in fact almost 96% of our body mass is made up of four different elements: hydrogen, oxygen, carbon, and nitrogen. Besides the physical way I am affected by elements, chemistry also majorly affects me in my line of work as a certified nursing assistant. As a certified nursing assistant I work in a nursing home and

Metabolism is a chemical process that converts fuel from food into energy needed for the body’s activities. For example, thinking, running and jumping etc. are all an example of the bodies activities.

“Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat, transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism, which help aid in the chemical reaction process. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions (Dowshen). Metabolism is a constant process that begins when we're born and ends when we die. It is a vital process for all life not just humans, and

Chemistry is undoubtedly in one’s everyday life. Every day, our bodies undergo chemical reactions and our environment that we live in goes through chemical changes. Completing this course, as challenging as it was, actually taught me so much about important chemical concepts that I didn’t even know or remember learning from previous courses. Our bodies cannot function without chemistry, so it is just as important to learn about the biological chemical process within because we need to know what is going on in our bodies, as well as in our surroundings.

From discovering elements, to the creation of the periodic table, to determining new trends, scientists continue to build upon and enhance existing knowledge of the basic components of chemistry. Chemists, as well as many other researchers, rely heavily on the periodic table of elements and its many properties that are widely accepted and believed to hold true. These elements are arranged on the periodic table according to their atomic number or the number of protons in the nucleus. How the properties of the elements correspond to their placement on the table is referred to as the periodic law or periodicity. The periodicity of early periodic tables was mostly relevant and accurate and for the lighter elements, those located in the first five rows of the periodic table, because they were more easily accessible and cheap. However, for the heavier elements starting in row six, some

Extremely important to organisms, phosphorus is a key ingredient to our DNA, RNA and the molecule ATP (responsible for giving living things energy). Discovered in 1669, phosphorus is used in fertilisers, safety matches, pyrotechnics, steel manufacturing and even in some detergents. Phosphorus is an important nutrient to both plants and animals as it contributes to the cell development. When facing not enough phosphorus, produce can decrease majorly.

The element I have chosen for our Atomic Structures And The Periodic Table Project is

A compound is defined as a substance containing two or more elements in a fixed ratio.

Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.

Chemistry is by far one of the most important sciences to humans, as it tells how the world around us is composed and tells us about why things act the way they do. Despite this many people find Chemistry to be one of the most confusing and hardest sciences to learn, and one aspect of which that may seem to be the most daunting is the Periodic Table. But in the national bestselling novel The Disappearing Spoon by Sam Kean, he uses a variety of topics to explain the organization, properties and other concepts related to the Periodic Table. In the chapter Elements in Times of War, Kean refers to historical events throughout history to show how the Periodic Table has influenced the way mankind has waged war. Through his use of historical anecdotes,

Chemistry has helped entertain Hollywood by making things for movies such as, fake snow, fake face parts, and when they’re making something explode and starting fires. A lot of chemicals are used for most of these things and without chemistry, we wouldn’t be able to do any of this stuff. The entertainment in making all this stuff was exciting to watch and see it all happen. You get to watch cool movies because of the stuff they do. You need a lot of chemistry for action movies and when cars light on fire. Chemistry is just really used for anything, but we wouldn’t have these kinds of movies without it.

Most elements on the Periodic Table are important to us. Like, Oxygen, and Nitrogen, or Hydrogen, without those, we couldn’t breathe, have our atmosphere, no water, etc. Although, Silicon and Germanium, two elements that are probably unknown to most people, but without these two, our world would be different.

Minerals, the group that copper belongs to, are critical to every chemical reaction that occurs in the body. Whether it's energy production, tissue manufacture, protein synthesis, water balance or cellular growth and reproduction, at least one mineral is required.

As we know, today there are one-hundred and eighteen elements on the periodic table of elements, but it didn’t start out like this. Robert Boyle, a scientist, discovered the element phosphorus in 1680. Also, in this year the element became known to the public. By the year of 1809, the number of elements discovered at the time was up to 47. Also, scientists began to see a pattern in the characteristics of the elements. Later in 1863, The 56 elements discovered at the time were then divided into 11 groups based on their characteristics by an english chemist named John Newlands. In the year 1869 a Russian chemist by the name of Dimitri Mendeleev started the making of the periodic table. He started by rearranging the elements in order of atomic mass. He also expected the discovery of other elements, so he decided to leave empty spaces in his table so he could add new elements later. In 1894, the noble gases were discovered by Sir William Ramsay and Lord Rayleigh. The noble gases were added to the periodic table in a group labeled 0. Eventually in 1945, Glenn Seaborg discovered and identified lanthanides and actinides. The Lanthanides were the elements with atomic numbers greater than 57 and lower than 71. The Actinides were elements greater than 92. These elements today are located underneath the periodic table (refer to figure 1). The last major change to the periodic table occurred in the 20th century due to the work of Glenn Seaborg. starting with his

Group 14 of the periodic table contains a mixture of non-metals (carbon and silicon), a metalloid (germanium), and two metals ( tin and lead). Tin is able to form dihalides and tetrahalides such as SnI2 and SnI4. However, lead will not form tetrahalides as readily as tin3. The tetrahalides of lead will decompose into dihalides due to their instability 3. The stability of the compounds is based on their respective oxidation states. Periodic trends suggest that group 14 oxidation states are normally - 4 as it is increasingly energetically favorable for them to accept electrons in order to complete their valence shells 3. However, due to the metallic properties of tin and lead, they generally lose electrons and therefore have a positive oxidation state. It is a characteristic trend to see heavier elements of the p block forming compounds in which their oxidation number is 2 (less than the group number 3 ). The heavier the atom, the more stable it is in the lower oxidation state. This is due to the inert pair effect 3. This can be correlated to the amount of energy needed to remove an electron (ionization energy), since in the higher oxidation state the p-block electrons and the s-block electrons are removed, while in the lower oxidation state, it is only the p-electrons that are removed and thus, the overall ionization energy is lower. The general periodic trend is that the ionization energy is generally lower for heavy metals, which results in the lower oxidation state being
