The Five Major Components Of The Atomic Theory

Improved Essays
The Atomic Theory states that all matter is composed of discrete units called atoms. The Atomic Theory started in about 400 BCE with a scientist by the name of Democritus. Democritus proposed the idea of the existence of an ultimate particle. He called this particle atomos when he was describing it, because the particle was too small to cut. Next, we get to Leucippus. Leucippus was the man who founded atomism, which is a theoretical approach that states nature consists of two principles, which are atom and void. After Leucippus came Aristotle. Aristotle believed there were four elements. These elements were air, earth, fire, and water. The matter of the world is made from a few fundamental building blocks of nature. He thought that it didn’t matter how many times you wanted to cut a form of matter in half, because you would always get a smaller piece of that matter. Antoine Lavoisier then proposed the Law of Conservation of Mass, which states the atoms of an object cannot …show more content…
The Atomic Theory is based on scientific evidence just like any other science-based theory. The Atomic Theory has five major components to it. The first component is that atoms cannot be created, destroyed, or subdivided. The second component is that all matter is composed of very small particles known as atoms. The third component is that all atoms of a given element are identical. Lastly, the fourth and fifth components of the Atomic Theory state that in chemical reactions atoms combine with or separate from other atoms, and atoms combine with each other in simple whole-number ratios to form combined atoms. Without the Atomic Theory we would not know the things we know today, like that for every time of matter there is an antimatter. Therefore, the Atomic Theory’s raison d 'être is to tell people all about atoms, and what they are and where they come from. So, the Atomic Theory is very

    Within these lectures he discussed his research on gases and liquids. This research gave remarkable new insight into the nature of gases. Thus became know as the Atomic Theory. The Atomic Theory states that: “all matter is made up of atoms which are indivisible and indestructible, all atoms of a given element are identical in mass and properties, compounds are formed by a combination of two or more different kinds of atoms, and a chemical reaction is a rearrangement of atoms” (Atomic Theory). Though most of this theory has held true we now know that atoms of the same element can have different masses and that atoms can be destroyed or subdivided in nuclear reactions.…

    (Doc. 1). They named their new idea ‘atomos’, meaning indivisible (OI). Sadly, their idea would be unsupported until 1803, when John Dalton published his atomic theory of matter. It stated that all matter was made of atoms, the atom is indivisible and indestructible, and that compounds are made up of two or more different kinds of atoms (OI). Years later, in 1911, Ernest Rutherford performed his gold-foil experiment and concluded that the atom has a positively charged nucleus and is mostly empty space (Doc 1, OI).…

    Ernest Rutherford’s model of the atom suggested the atom had a small, compact nucleus surrounded by a cloud of almost weightless electrons. Bohr proposed adding to the model the new idea of quanta put forth by Max Planck in 1901. That way, electrons existed in set levels of energy, that is, at set distances from the nucleus. His model was a huge leap forward in making theory fit experimental evidence that other physicists had found over time.…

    Originating from cosmic events such as supernovas, chemical elements are the foundation of all life. Billions of years ago, a violent explosion known as the Big Bang produced helium, hydrogen, and all of the matter and energy in the universe. Generated in the cores of stars, nuclei combined to form atoms which constitute the basic unit of all chemical elements. The extensive expansion of the universe induced the birth and demise of more stars and consequently the creation of more elements.…

    Scientists believe that stars are made of mostly gas, and this gas is made up of many atoms. In the star, the atoms in the gas bang into each other and give off different light depending on the type of atoms. This light from stars enables scientists to figure out the type and amount of atoms they are made of. Knowing the composition of the stars, we can guess how they were formed. Therefore we can see that stars are just atoms (hydrogen) hitting each other producing light.…

    Today we might know an atom being the smallest piece of an element that represent an element, but you might not know the whole story. It all being in 1803, when a curious guy, known as John Dalton, who proposed an “atomic theory” with spherical solid atoms based upon measurable properties of mass. Later on Dalton introduced his belief that atoms of different elements could be universally distinguished based on their varying atomic weights. John Dalton's research not only changed the face of chemistry but also initiated its progression into a modern science.…

    Within the body of a child dwelled an atom, who helped to make up the elements that dwelled in the body of a child called Alex. Even though, the atom was the smallest unit in the whole body, it helped to make sure the daily needs of the body were met. The atoms acted as the tough guys of the body because they were big in number, or so they thought. They would often compare their amounts of neutrons, protons, and electrons to one another and drawing out structural and molecular formulas, to make it look like their electrons would increase alternating between the drawings. However, their atomic number, atomic mass, and isotopes reminded them no matter how much they tried to compare, they would end up bonding both ionic and covalently, whichever…

    An atom is a basic unit of an element. For thousands of years, people have been questioning about these tiny particles and have came up with many theories based around it. Though many people believe atomic theories started with John Dalton around the late 1700s or early 1800s. This is not true as the atomic theories started sometime during 300 or 400 B.C. with the philosopher, Democritus, being one of the first to come up with a theory about atoms. Democritus’ theory gave the basics of an atom; but his theory was rejected by many during his time as fellow philosophers, Aristotle and Plato, rejected his theory ("The History of the Atom").…

    On the eleventh of October 1939 the President Franklin Delano Roosevelt received a letter from the one and only Albert Einstein, which Albert Einstein had actually wrote on August 2 1939. The letter mentioned of a new field of physics that was showing that the element uranium could undergo nuclear fission, with the resultant release of a remarkable deal of energy. Ever since the Greek man named Democritus stated in the year of 450 B.C. that everything in existence is made of atoms, ever since then scientist have been working to figure out what an atom is exactly. Einstein described the probability that a nuclear reaction could be produced and the possibility of the construction of overpowered nukes that would devastate and demolish…

    This theory is based on the idea that under a microscope, an electron is a tiny loop of a string (Güijosa). Characteristically, that string can oscillate, and if it does so in a certain way, it appears as an electron, but if does in other ways, it can be seen as another subatomic particle (Güijosa). Essentially, everything is made of strings that vibrate in a way that give them distinct properties ("String Theory”). Similarly to an instrument such as a piano, different frequencies produce different particles, and this comparison brings forth unification (Greene 2005). This concept is reinforced by physicists’ recent detection of gravitational waves, which can be used to help further “probe” into more radical theories…

    At the end of the nineteenth century, scientists believed that all matter was composed of atoms. However, an English physicist named J.J. Thomson (1856-1940) discovered an even smaller particle that he called corpuscles, although we know them as electrons today. Thomson discovered that electrons are negatively charged, that they are much smaller and have less mass than atoms, and that they are uniformly present in many different types of substances. With this new discovery, the question of a balancing positive charge arose. Atoms are known to be charge-neutral, so it was believed that they must contain a positive charge that balanced the negative charge of the electron.…

    The atomic theory states that all elements are composed of atoms. He also realized that all atoms of a specific element would have the same characteristics. Lastly, he found that an element is always made of the same proportion and atoms can use different proportions to form different elements. Although Dalton did a great deal to define the atom, he was unable to make any progress with the structure of the…
