Atomic Theory Essay

We are first going to talk about Protons,Neutrons and Electrons. These three elements are a very good example of most things that are in use of gas fumes. It all started when Protons and neutrons where, Protons were discovered by Experimenting with discharging tubes. Eventually they found out the rest of the Atoms over time. Which brings me into the word of Orbital. Orbital is a Neutron, electron or a proton Going around a single atom with certain amounts of energy levels. Which are all made up in the Cloud. The cloud is a intense color representing how many atoms are not representing a electron.
When you have a Atom and you don't know what its called or how it was made you can look at the periodic table. The periodic

But those are only the Fundamentals of what you need to know unlike the complex stuff that we are about to get our hands into later on. The thing that is like a brian for a element is called a Nucleus. And most of the nucleus are made up into one big Atomictheory. Speaking of the atomic theory Dalton's atomic theory had three major aspects to his research one would be Atoms are invisible and indestructible, all matter is made up of atoms and last but not least Compounds are formed by a combination of two or more different kinds of atoms. Space is a very crazy thing because you never know what kind of things are in space because of the fact that behind everything is a new discovery and some major kinds of discoveries are Technology , Technology is a major kind of thing that is used in today's daily lifestyle everyone uses it at some point in the day and especially for science or chemistry. Which brings me to the man named JJ Thomson he is a very important guy. JJ Thomson made the identification of a electron. And showed us how the electron works. James Chadwick was the man who had discovered the neutron in late 1932 the neutron is a type of element that …show more content…
A Cathode Ray is mainly a stream of electrons that mainly attack one beam of light. Which brings us into what a Discharge tube is a discharge tube is a tube containing electrodes and filled with gas in which ionization is added by an electric field. S,P,D and F orbitals are a major key in what we call the Electronic Configuration they are what make up the whole electron configuration. Positron is like a subatomic particle with the same mass as an electron and a numerically equal but positive charge the Probability of the electron not being the same would be very slim. The way that Einstein would have looked at it was he would have tried to make things better by always trying out things and experiment things so he could be able to invent something new always. In the Early 1900’s science was a really big factor in how they all had something new either it being technology or something in the event of there being cars around and having to do electrical work on how there is always something to do with science no matter what you have to do. As the years went on in 1909 they started to begin the

    Although Joseph John (J.J.) Thomson (1856 - 1940) was mainly a physicist, his discoveries are closely connected to the chemical community. Thomson used Crookes high vacuum cathode ray tube in his discovery of electrons. He found the green beam produced by the cathode ray tube was a completely negatively charged material. Experimenting with different electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles smaller than atoms existed. By doing this experiment multiple times he compiled enough data to conclude that the mass of one of these particles, which he called an electron, was lighter than an atom of hydrogen by around 2,000 times. He also found the ratio of charge to mass (e/m) would be the same for any electron.…

    BIOLOGY STUDY GUIDE CHAPTER 4– THE CHEMICAL BASIS OF LIFE Matter = anything that takes up space and has mass (major types of matter = solid, liquid, and gas) Any type of matter is made of one or more elements. o Element = a substance that cannot be broken down into other substances by regular chemical processes. (examples: gold, silver, mercury, etc.) There are approximately 25 elements necessary for life. • Examples: oxygen, carbon, hydrogen, nitrogen, calcium, phosphorous, etc. • Trace elements = those elements that make up less than 0.01 percent of your body mass (examples: iodine, iron, copper, etc.) Compounds = a substance containing two or more elements; these elements are always present in this compound in the same ratio o For instance, water is a compound where hydrogen and oxygen are combined. The ratio of hydrogen to oxygen in water is always 2:1. (Remember that the chemical formula of water is H2O.) o Compounds have different characteristics than the elements that make them up. (Water is liquid at room temperature, but when hydrogen and oxygen are by themselves, they are gases at room temperature.) Atoms = smallest possible piece of an element o A better definition of an atom may be: the most basic unit of matter that cannot be broken down into smaller pieces by ordinary chemical methods. o This can be confusing, because when you read the above definition or when you start looking at the periodic table in class, is oxygen an atom or an element? o An element is essentially the same as an atom. Why do we bother with two different words? • An element is the most common version of an atom. The element you see on the periodic table for oxygen is the most common version of the oxygen atom that exists in nature. There are several different kinds of oxygen atoms (with different numbers of neutrons than the one found on the table), but they are not as commonly found in nature. All atoms are made of even smaller…

    Elements are the building blocks of which all things are composed. The elements of Earth are made up of atoms. All atoms possess a nucleus of positively charged protons as wells and neutrons which are neutrally charged. Surrounding the nucleus is a low density area containing negatively charged electrons that are equal to the number of protons within the nucleus. The number of protons within an atom determines the element that it composes. Every element within the Periodic table is defined by its atomic number (the number of protons in the atom). Elements with an atomic number between 1 and 92 are naturally occurring elements. Every element with an atomic number higher than 92 (having a nucleus with more than 92 protons) is a synthetic (man-made) element. The larger the atomic number, the heavier the element.…

    Dmitri Mendeleev’s Periodic table is based on atomic weight, whereas, the modern periodic table keeps the atomic number as the base. An atomic table arranges elements from left to right in a row with the atomic number and properties gradually changing. The elements on the next row will actually exhibit similar properties as the ones above or below it. This provides an example of the periodicity nature of the elements. The columns of different elements in a period have the same or very similar properties. The properties of the elements change gradually as the columns move down through the periodic table. Atoms in similar families, such as H2S and H2O, exhibit both similar properties and molecular structure. This shows periodicity in both the molecules and the individual atoms.…

    As he did these extraneous experiments, John Dalton proposed that every chemical element is made of atoms of a single, yet unique type, which cannot be demolished or transformed. In chemical means they cannot be changed although atoms can be combined to create more intricate structures, which are known as chemical compounds. After all of his research and analysis of the results he then concluded that this was the first scientific theory of the atom.…

    From the title of this book, I could infer that the book will be about how the elements were discovered, the origin of their names and the people who discovered each element that is now a part of the periodic table. The author of the book, Hugh Aldersey-Williams, must be an individual of great knowledge and has a deep interest and understanding of chemistry—or else he would have never wrote this book. In this book, I expect that I would be able to learn how the ancients used the elements to improve their way of life, and how our advancements in technology relate to our understanding of the elements.…

    Atoms, molecules and elements are the building blocks of everything we can see, hear, and touch. Though not visible to the naked eye, it is the combination of millions of these tiny substances that make us who and what we are today. Many elements make up the world around us, and each element reacts differently to its surroundings.…

    It took many scientists and philosophers hundreds even thousands of years to come up with an accurate atomic theory. For nearly 2,000 years science was unable to come up with experiments that were able to test and put forth the theories made up by Democritus which was a fifth century B.C. Greek philosopher. In 1803, John Dalton, who viewed the atom as a small solid sphere, and is credited for the developing of the first coherent atomic theory was now in the picture. This all led to the the first periodic table of the elements, and the history of the atom.…
