    Scientists work? Why? I believe that the scientists before Rutherford would have inspired him to investigate in Atoms. This may of occurred because there was a conspiracy towards the atoms due to nobody actually seeing them. What part of the Atomic Theory did they investigate? Ernest Rutherford was responsible for a many different discoveries such as radioactivity and nuclear physics. He discovered alpha and beta rays, found the laws of radioactive decay, and identified alpha particles as helium

    energy in all kinds of matter. The atomic theory became a very important piece in chemistry because it explained the atomic structure and how it worked. Important scientists that helped contribute to this theory were people like John Dalton and J.J. Thompson which helped establish a foundation to the theory, as well as create experiments that helped provide evidence of their findings. John Dalton was an important scientist that established the atomic theory. His theory was as follows: 1.All matter is

    Atomic Theory The ancient Greek the word atom means indivisible. It was used to describe the smallest indivisible piece of a matter. He believed that all matter could be broken down using femtometers. Atoms were perceived to be indestructible. Atom was derived from the greek word atomon or atomos meaning indestructible. This fundamental atomic theory was developed by a scholar named Democritus. He was a pupil of the famous philosopher Leucippus. From Democritus’ original Atomic Theory

    Atomic theory is the idea that matter is made up of small particles made of atoms. The atomic theory first had 5 points which were stated by John Dalton who came up with it. The first one was that all elements were made up of small units called atoms. The second one was that all atoms of a given element are identical to each other. Third, all the atoms were different from all the other atoms. Fourth, atoms of different elements combined together in equal numbers to form compounds. Fifth and final

    research of numerous chemists and physicists. The atomic theory is the building block to the study of matter, just as the atom is the building block to all matter. Around 400 BCE was when the Greek philosopher Democritus, alone with his teacher Leucippus, the idea of the atom was born (the word atom comes from the Greek word “atomos” or “atomon” meaning “that which cannot be split”). This was a completely new concept, and Democritus’s theory stated that atoms were indestructible and homogenous

    “What is the world made of?” That question has puzzled scientists and philosophers for centuries. The atomic theory was first proposed in ancient Greece around 400 BC and has continued to evolve through the centuries to finally evolve into the current theory we have today. We now know that the subatomic particles that make up the atom are no longer the fundamental particles of the universe because even they are made of smaller particles called “quarks.” The continuous study of atoms will allow us

    The Atomic Theory’s Scientist are Mostly German Thomas Britton & Kate Caufield New Albany Mr. Mumaw’s 6th Period Chemistry Abstract The atomic theory has been worked on since around 400 BC. It is a theory that helps us to understand what everything in the universe is made of and what those particles are made of. It also helps us to describe the relationship between the sub-particles and how they may contribute to different aspects of the atom, like it 's mass or charge. These atoms then go on

    relationships of the ancient Greek beliefs and the existing theories and truths. Mathematics, as it relates to the Greek era and the present time, had created and still creates a very new approach to the thoughts of the mechanics of nature. For instance, Pythagoras, the Greek mathematician and philosopher, believed the physical world would be explained by numbers. He used his theory of numbers and applied them to
