The Discovery Of The Atom

It was a great day in May of 1932 and when we finally received answers to the other particle in the nucleus. After many years of questions and theories; one man James Chadwick has discovered a new uncharged particle, the neutron. Chadwick had been studying to find this particle since 1914 in Germany with Hans Geiger, unfortunately due to World War I he was arrested and his studies were put on halt. Although he was in prison he was still able to do some scientific studies after creating a science club with some fellow prisoners; and convincing the guards to allow them to have a lab. Eventually he was released and return to England where he earned his PhD at Cambridge with Ernest Rutherford.

What is an atom? An atom is the basic building block of everything. An atom is made of electrons protons and neutrons and the number of protons determines the element. Back in the 1800’s this whole idea was unknown. In the 1800’s steam was starting to power everything. It became important to know how steam works, so you can learn to use it more effectively. It was this idea that drove Dalton to research the atom.

This is the origin story of the “The Atom”, it is a tale chock-full of danger and sorrow. It is a very tragic tale indeed. There was once a seventeen-year-old boy named Adam Spencer, he lived in a quaint little town called Greendale. Adam is the smartest student in his grade, he has an IQ of 145, and he’s the son of the two most famous chemists’ is the world. Being an only child strengthened his bond with his parents even more. They had lived a simple life, until that fateful day when everything had fallen apart.

Throughout history, science has been evolving and changing in a variety of ways. A vast number of proclamations have been both proven and disproven over time. An example of an ever-changing statement is the Atomic Theory of Matter. This theory states that matter is composed of extremely small units called atoms, what those atoms are made of, and what they do. This theory dates back all the way to ancient Greece and was most recently updated in the 1920's. Five main scientists have had a part in shaping and evolving this theory. They are Democritus, John Dalton, Joseph John Thomson, Ernest Rutherford, and Neils Bohr.

Niels Bohr was a famous physicist, born in Copenhagen, Denmark in 1885. He accomplished many things in his life, some of which include, winning a Nobel Prize in physics for his quantum mechanical model of the atom and developing the “liquid drop” model. Bohr was always interested in science, even at a young age. He went to Gammelholm School for his primary and secondary education in 1903. Bohr then went on to receive his doctorate from the University of Copenhagen in 1911.

What is an atom? An atom is a small particle that makes up most types of matter(OI). The atom was first discovered by Democritus in about 300 B.C.(Doc 1). He believed that bits of matter were too small to see and could not be divided. As a result he named it the atom, which means cannot be divided in Greek. This was the first step to understanding matter. The next person to study atoms, 2,000 years later, was a French chemist by the name of Antoine Lavoisier(OI). From his experiments,

An atom is the smallest part of matter that keeps its characteristics. Atoms are the building blocks of matter; all matter is made up of atoms. Atoms are made up of subatomic particles. The subatomic particles are protons, neutrons and electrons. Protons have a positive charge and are found inside the nucleus. Neutrons have no charge and are also found inside the nucleus. Protons and Neutrons have a charge of 1. Electrons are found outside the nucleus, in an orbit or shell. Electrons have a negative charge and a mass about 1/2000th of the mass of a proton/neutron. An atom contains the same number of protons and electrons, which means it contains the same number of positive and negative charges. The positive and negative charges cancel each

Chemistry has been around since around 400 BC. In 450 BC Empedocles set back the world of chemistry by proposing that all matter is made up of four elements, air, water, earth, and fire. But in 440 BC Democritus attempted to set the world of chemistry back on track by proposing that all matter is made up of indivisible atoms that are too small to be seen. But, without the technology to prove such a theory the world followed in Empedocles footsteps. Later in 350 BC further expanded upon Empedocles ideas of the four elements adding a fifth, aether, this theory soon became widely accepted and would continue to be accepted for the next 1000 years. From here on alchemist took over and made many advancements in chemistry although their main goal

We know that atoms make up everything around us. So we need to know what is in an atom. First there is the nucleus the nucleus is located in the center of the atom. In the nucleus there are protons, protons have a positive charge. There is also neutrons in the nucleus they are neutral they don't have a charge in other words they have no charge at all. Atoms make up

Everything that exists in the world is made up of atoms, from the asteroids that float around in space to the very cells inside a human body. Atoms are everywhere and that’s because atoms make up everything. Atoms are made up of protons, neutrons and electrons, each element has different amount of protons, neutrons and electrons. For instance one Helium atom has two protons, two neutrons and two electrons. Helium is an extremely stable element so there are no variations such as ions or isotopes. So we know that atoms make up everything in the universe and atoms are made up of protons, neutrons and electrons. So what makes protons, neutrons and electrons?

Francis Crick (8 June 1916 — 28 July 2004) was an English scientist who was most noted for being a co-discoverer of the structure of the DNA molecule in 1953 alongside James D. Watson.

The development of the atomic model began in 400 B.C. when Greek philosophers, Leucippus and his pupil Democritus theorized the existence of atoms. They came up with the idea that matter of composed of tiny particles, but didn’t think their theory was particularly special. They knew that at a certain point it was impossible to divide matter so they coined the term ‘atomos’ with literally meant “uncuttable” or “indivisible”. They also attributed the properties of the atoms from the properties of the substance. The two philosophers achieved their theory without any experiments but, by solely on insightful guesses.

Henry Cavendish had isolated hydrogen in 1766. He soon called “inflammable air.” In 1773, Carl Wilhelm Scheele discovered oxygen. He came to call this “fire air.” Scheele had not published his achievement soon enough, and Joseph Priestley did instead. Priestley revered to oxygen as “dephlogisticated air.” He had also invented soda water. In 1789 Antoine Lavoisier, father of modern chemistry, established the law of conservation of mass, Lavoisier’s law. He had made a system which named chemical compounds. This was put into his book called Methods of Chemical Nomenclature in 1787. This chemical compound naming system is still used today. John Dalton proposed Dalton’s law in 1803. This law describes the relationship the makeup in a mixture of gases and the pressure that each contributes to the mixture. Dalton had also proclaimed in 1803 that all matter was composed of small indivisible particles. In 1808 he published New System of Chemical Philosophy where he proposed a modern atomic theory. In this book he made an outline of the identification of the atomic theory. Dalton claimed that atoms of a given element possess unique characteristics and weight, and three types of atoms existed. Those three types are simple (elements), compound (simple compounds), and complex (complex molecules). There were many uncertainties about Dalton’s published book. In 1811, Amedeo

The world of physics had been developed a well-established model of the atom. The standard model had been pretty well “tied up”, with its group of 16 elementary particles and their nice set of rules describing how they should interact. Physicists had observed until the Higgs discovery, 16 of these particles. The crowd was already beginning to desperate for a 17th particle that would send the model in new and wild directions (supposedly). But the Higgs particle ruined the hopes and expectations of everybody: it turned out to be very ordinary: its behavior was just like the model said it would act, obeying every theorized rule [2]. Therefore, the Standard Model is vindicated. And this was a

Antoine Laurent Lavoisier was born on August 26, 1743 in Paris, France he would be the only child of a wealthy middle class family. He was very studious and extremely interested with the prosperity and the good of the public. Antoine education consisted of the study of mathematics, the classic, and sciences. He chose to pursue a career in chemistry because of the interest in rocks and other minerals. He also had a passion for law and went to law school after he finished college and later studied humanities and different types of sciences. He also spent much of his time attending various lectures about chemistry and physics because he didn’t find the teachers to be very demanding of his effort and time.
