Cobalt Origins

The scientific method in the twenty-first century represents a major role of testing our hypothesis’ whether it is in the industry, school, market, or in our lives. We are constantly coming up with theories or ideas and conducting experiments on these ideas without even realizing it. The scientific method allows us to expand our knowledge in certain fields that we are mastered in or helps us learn new possibilities that we are not aware of. The use of chemistry and the scientific method is important to incorporate into our lives and society.

Growing up in suburban Detroit, David Hahn was fascinated by science. He often conducted experiments in his basement and enjoyed making things such as homemade fireworks, brewing moonshine, and even making his own self-tanning lotion. Hahn especially loved chemistry and spent much of his time doing amateur chemistry experiments. The chemical reactions in these experiments sometimes went wrong and resulted in small explosions. We learned about chemical reactions in class this semester. He loved to read “The Golden Book of Chemistry Experiments” that his father had given him and tried to collect samples of every element in the periodic table, including the radioactive ones. We learned in class about the elements in the periodic table and how they are identified.

In chapters ten and eleven of the Disappearing Spoon, by Sam Keane, the focus is placed on the interaction between elements and the human body. The reader is taken on a journey through the medical history of various metals, and their beneficial factors. The trip continues to the interesting topic of chirality, or “handedness” of different proteins. On the flipside, the deadly aspects of different elements, as well as their deceptive ways are discussed. These two chapters really grabbed my attention, as medical history has always been of interest to me. Furthermore, it was very fascinating to me that such small differences in compounds, such as handedness, has such a large effect on the human body. Keane aptly proved our knowledge of elements expands, our medical capabilities multiply, and not to trust elements too easily.

Discoveries can manifest themselves in many ways and can be evoked by one's curiosity, necessity or wonder. The

Oxygen is a highly reactive nonmetal element that is a colorless, odorless and tasteless gas. It is the third most abundant element in the universe by mass, makes up 2/3 of the mass of a human body and about one-fifth of Earth’s atmosphere (Helmenstine, 2016). The discovery of this magnificence element can not credited to solely one individual. Both Joseph Priestley and Antoine Lavoisier should receive credit for proposing new ideology and experimental findings that lead to the discovery of oxygen.

The History of the Periodic Table of elements is vast, and filled with interesting facts that not many average people would know about, these four scientists have had all contributed to the table in some way, and lead it to its current state, here is what they have

Every element is valuable and unique due to the endless arrangements of sub-atomic particles, which fascinates me. This allows for a diversity of elemental properties, sparking innovation for chemists to develop new products from different tasting chocolates to materials used for rockets- shaping society and the environment of the modern world. The sheer range of applications where chemistry is involved inspires me to contribute, while learning, unlocking why everything behaves the way it does.

There are many different experiments which can give varying intelligence about the makeup of matter, in different ways and with different conclusions. In this instance I will be looking at the discovery of the electron, how our understanding of it has changed over the years, and measure how it has contributed to where we are today.

To wrap your mind on what this element really is, here is the basic knowledge on Cobalt. Cobalt, is the 27th element on the periodic table from the fact that it has 27 protons. It is also referred through the universal symbol Co and is a transition metal. There are 8 different isotopes in Cobalt 1 of the them is stable meaning it will not decay or change into any other element. With a melting point of 1495 degrees celsius and a boiling point of 2927 degree celsius this metal needs lots of energy to change state. The element in its pure form is silver and blue, but fragile to the touch. The history of

Ever since the discovery of the nucleus of the atom in 1911, the world has been influenced

Cobalt 60 is one of many radioactive isotopes. It contains 33 neutrons and 27 protons. Most people have not heard of Cobalt-60 unless they are involved in chemistry or the medial field. This isotope is more common than a person thinks. It is an isotope that is useful in the medical field and other places. This paper is all about Cobalt-60 and the history behind it as well as some other useful information.

To start off with some standard facts about Cobalt are; atomic number which is 27, atomic weight-58.933149, melting point-1768 K (1495°C or 2723°F), boiling point-3200 K (2927°C or 5301°F), density-8.86 grams per cubic centimeter, phase at room temp-solid, element classification- metal, period #-4, group #-9. The apperance of Cobalt include a lustrous, silvery-blue metal. It is lustrous, hard, brittle metal, and magnetic.

Copper is necessary and beneficial in the human body, but only in very small quantities. In larger amounts, it becomes toxic or potentially lethal.

Every single day, without even realising it, we use so many things that are brought to us by the discoveries and advances in chemistry. Many of these things we take for granted, and don 't even bother to question how it got there, why it is there, and how it works. Chemistry makes up everything in our lives, from the air that we breathe, to the plastic on the keyboard I 'm typing on now, and a in depth study of some of the wonderful things chemistry has do for the modern day world, will help us to appreciate everything we have a great deal more.

Discovery – finding a previously unknown natural law, material, property or other information - basic science/research (quantum mechanics, genetics, periodic table, relativity, DNA)
