The Nature Of The Atom And A Model

The atomic theory is very well known across the science community. It took many scientist to get it to what it is today. Aristotle and Democritus are played major parts in forming the atomic theory. They came up with a bunch of theories and made big contributions to the start of the atomic theory.

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.

What is the atomic structure you may ask? Well, it’s the law stating the structure of an atom. It is composed of a positively charged nucleus containing a certain amount of protons (positive), neutrons (neutral charge), and electrons (negative). The amount of each subatomic particle (proton, neutron, and electron) all depend on what the element is. Now although this statement may seem fairly simple it was most definitely not. People have been studying the atomic structure for more than 300+ years and are still studying it. So after reading this you may wonder who even made this atomic structure up. After hundreds of years of research there is not any one individual who made the structure up but roughly

Within the last hundred years, the atomic model gone through dramatic changes allowing to apply the knowledge of matter understanding at atomic level into different industries like medicine such as MRI and X-Ray. This knowledge allowed doctors to treat, diagnose and certainly save millions of people throughout the years, which could not have been done without research being done on the structure of the atom funded continuously for these scientists to find more application which benefit people and comprehend the world we live in on an atomic level.

Democritus made the atomic theory widely known, which stated that the universe is composed of two elements: the atoms and the void in which these atoms exist and move. (More, 1646)

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.

Before Rutherford’s Geiger-Marsden experiment the most popular model of the atom was the “plum pudding model” developed in 1904 by the person who also discovered the electron in 1897, J.J. Thompson. It was the most common model of the atom and stated that electrons (plum) floated around with

One of Bohr’s most renowned accomplishments was his contribution to the atom. He discovered that the atom was a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus. Most physicists run experiments in order to come

Rosalind Franklin and Maurice Wilkins used x rays to study DNA. Their research let James Watson study the structure of DNA. Watson ended up discovering that the structure of DNA is a double helix in 1953. All their research helped develop the DNA theory.

Leucippus and Democritus discovered the atom(doc. 1). Ernest Rutherford split the atom and discovered that the atom is made of smaller particles and that atoms have a positively charged nucleus and largely empty space(doc. 1). Without Leucippus and Democritus, no one could expand on the idea of the atom and without Rutherford no one would have thought of the nucleus and what is inside the atom(doc. 1). Atoms are so small

Ernest Rutherford, a Britain born physicist, is credited for the creation of nuclear physics. Rutherford, while studying the effect x-rays had on various metals, shortly after his discovery of radioactivity, was intrigued by the components of Uranium. In search of finding a way to count individual light particles, Rutherford discovered the effects of zinc sulfide.

Niels Bohr greatly contributed to the modern atomic model. He provided great knowledge on the atom and physics. He is considered to be one of the greatest physicists of all time because of his contributions to the atomic model. This required the help from a few of his fellow physicists, such as Ernest Rutherford and J.J. Thomson. Niels Bohr created the Bohr model in which he built his ideas from Rutherford and Thomson to create what he thought the atom looked like. Bohr believed that the middle of an atom is a positively charged nucleus with electrons surrounding it. He also discovered that the electrons were not in a specific orbit around the nucleus instead, they jumped around depending on the amount of energy they had.

The Discovery of the Atom first came from the Greeks which made a theory “The idea that all matter is made up of tiny, indivisible particles, or atoms, is believed to have originated with the Greek philosopher Leucippus of Miletus and his student Democritus of Abdera in the 5th century B.C. (The word atom comes from the Greek word atomos, which means “indivisible.”)” (InfoPlease Atomic theory)

John Dalton was an English chemist, physicist and meteorologists, his work today helps us better understand the model of the atom and the way that the atom functions. Dalton’s work provided the evidence that elements contain atoms. Thomson tinkered with experiments and investigation and after numerous experiments using a Cathode Ray Tube helped him to discover the electron. John Dalton’s beliefs, however, were that the atoms were highly indivisible particles, furthermore Thomson’s Discovery of the electron proved the very existence of subatomic particles (i.e. an electron). This discovery of the atom was made in 1897 and 7 years later in 1904 the model of the atom was first proposed. When Thomson first developed a concept of his research

Niels discovered more about the orbitals and how the protons, electrons and neutrons worked and how the orbitals worked and were set up. Ernest’s discoveries set up future discoveries to be made. If he didn’t discover the nucleus in the atom, we wouldn’t have the atomic bomb. (Which would probably be a good thing.) Colleges and Scientists still use the gold foil experiment to learn from, and they still look to his information for reference and help in their current work.
