Investigating The Chemical Reactions Between Atoms And Atoms Essay

Once upon a time, the atoms which make up everything, including our bodies, were formed in the stars. Most of those stars are dead now but they left us the most important legacy – atoms. Atoms are small particles which make up everything. From the chair you're sitting on, to the nails on your left hand, your funny nose you so desperately dislike. Those atoms, of course, form more complex structures which make us breathe, and run, and sleep, and read, and cry. They make up our life. Sadly, our atoms at one point become too tired of us and they want to escape. We may get sick, or be hit by a bus, or we may one day just not wake up. When they decide to leave us, there is no coming back. We die.

Other elements depending on the cells by types and domains (discussed above) vary and together they form compounds (Simon, Dickey, Reece, & Campbell, 2013). The ways elements develop formations to create compounds are called bonds and the bonds are Molecular and Chemical. There are 2 types of Molecular bonds where Ionic bonds form by attracting oppositely charged ions and Covalent bonds form by two atoms sharing one or more pair of negatively charged subatomic particles (Electrons). Chemical bonds such as Hydrogen bonds occur through the changes in chemical composition of matter which are called chemical reactions. The difference between covalent (molecular) and chemical bond is that in chemical bond, the electrons are not shared among particles but the particles just orient themselves together similar to the attraction of magnetic polarity to create a bond. All types of bonds, Ionic (e.g. NaCl – Salt), Covalent (e.g. O2 – Oxygen), and Chemical (e.g. H2O – Water) contribute to the composition of cells that are necessary to sustain life.

Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. Also the investigation of their properties and the ways in which they interact, combine and change. Matter is based on the physical and the chemical structure and matter is made up of atoms. There are three states of matter and they are solid, liquid, and gas. The properties of a solid, liquid, and gas all depend on how the particles are packed.

In this lab we were asked to observe changes and colors when mixing two or three chemicals together. The actual experiment itself used twelve different pipits and three chemicals I selected from my house. To begin, I first gathered everything, including the 96 well plate, 24 well plate, goggles, and gloves along with the observations of chemical changes bag. I set it up all on the the kitchen table that had paper towels on it. Next, I made my data table so that I could record my reactions. Third, I sat all the pipets in the 24 well plate. At this point, I began the lab by following the instructions for each chemical. I had to drop two drops of the first chemical into one well, followed by two drops of the second chemical

An atom is contained of a nucleus holding positively charged protons and neutrally charged neutrons. Surrounding the nucleus of an atom are negatively charged electrons. In a neutral atom, the number of electrons and protons are the same. However, the solidity of an atom, is the tendency for the atom to gain or lose electrons, is directly proportional to the number of electrons located on the valence of the atom, the outermost part of the shell. The stability of the electrons determines the physical properties of a particular compound and can be used to determine if the bone is either an ionic or covalent bond.

In this treatment, the classifications of bonding, ionic or covalent, are retained, but they are given physical definitions in terms of the actual distribution of charge within the molecule. In covalent bonding the valence charge density is distributed over the whole molecule and the attractive forces responsible for binding the nuclei are exerted by the charge density equally shared between them in the internuclear region. In ionic bonding, the valence charge density is localized in the region of a single nucleus and in this extreme of binding the charge density localized on a single nucleus exerts the attractive force which binds both nuclei.

The atom is an important thing in the world of science and chemistry. The atom might have started on a different point of view on how the atom works. There were many different people who had many good and different ideas on how to use the atom and what it was used for. Democritus was one of many other philosopher and scientists that wanted to start the discovery of the atom. He got the name atom from a Greek word, atomos which means that everything is uncut table. The atom was discovered by Ernest Rutherford while he was doing an experiment in 1911-1919. Ernest Rutherford suggested at first that the atoms orbited around atomic the nucleus, just like the planets. Atoms are basic units of matter that are made of protons, neutrons, and electrons. Protons and neutrons are particles that are found in the center of the atom, and the electrons are particles that are found in shells that orbit around the nucleus of the atom. The nucleus was discovered in 1911, by Ernest Rutherford and it is known for holding the protons and neutrons, and it 's also in the middle of the proton. Atoms have many other things that are special and important to use, but one of the most useful thing is the Periodic Table, a table of the chemical elements arranged in order of the atomic order. The most important things for the history of the atom are the basic units of matter which make the atom

Chemistry is a branch of science commonly defined as “the study of the structure, properties, and reactions of the chemical elements and the compounds they form” (The American Heritage Science Dictionary, 2002). This definition is very general and covers a range of study areas, including those that are an asset to society. Chemical reactions are studied by many chemists as they common occurrences in everyday life (Stewart, 2014). Without chemical reactions people would be unable to perform simple tasks that are essential for quality of life and even life itself, such as cooking, lighting a match and breathing (Helmenstine, 2015). A chemical reaction occurs when a chemical change takes place, producing new substances. However, all chemical reactions are different and vary greatly in the time it takes for them to occur (Chem4kids.com, 2015).

How did the different scientists contribute to the creation of the modern atomic theory? Why would they be accepted?

Twelve was a terrifying age for me. It was the year that everything became open to doubt. That year I questioned all subjects from God to gravity. My friends seemed unreliable so I ostracized myself, avoiding all intimacy and any semblance of amiability. I stopped listening in church because my Sunday-School lessons brought up more questions than I was capable of dealing with. Instead I concentrated on the two constants in my life, school and family. Education and love became the two pillars my world was balanced on.

Many of the chemicals we encounter everyday are molecular in structure. Molecules are specific combinations of atoms. The oxygen we breathe in and the carbon dioxide we breathe out are both molecular in their structure.

Nuclear technology: a mysterious frontier in scientific advancement that has enraptured spectators worldwide. As the influence of nuclear technology expanded, nations implemented policies to address its usage. The Atoms for Peace program contributed significantly to the conception of these policies. This program’s inception represented a turning point in international cooperation. From Atoms for Peace arose the International Atomic Energy Agency (IAEA), the spread of nuclear energy, the technology’s risky dual use, and the rise of conflicts over Iran’s highly controversial nuclear program. The effects of the Atoms for Peace program play roles even in international affairs of the present.

Chemistry is the science of the composition, structure, properties, and reactions of matter, especially of atomic and molecular systems (dictionary). And technology is the branch of knowledge that deals with the creation and use of technical means and their interrelation with life, society, and the environment, drawing upon such subjects as industrial arts, engineering, applied science, and pure science (dictionary). Chemistry helps our advances in technology, and technological alterations that affect our lives in many ways everyday. Because of science, we have complex devices like cars, X-ray machines, computers, and phones. But the technologies that science has motivated consist of more than just hi-tech machines. Technology extends our

The history of chemistry makes a span of time reaching from ancient history to the present. By 1000 BC, ancient civilizations used technologies that would eventually form the basis of the various branches of the subject. Examples include extracting metals from ores, making pottery and glazes, fermenting beer and wine, extracting chemicals from plants for medicine and perfume, rendering fat into soap, making glass, and making alloys like bronze.

I am going to discuss the modern concept of the atom. I am going to give a brief history of the atomic model including Thomson's atom, Rutherford's atom, Bohr's atom, and Schrödinger's atom. I am going to include a diagram for each of these models.
