    Ancient Atomic Theory & John Dalton Many people struggled to understand the nature of matter. Some said it was made of water and some said it was fire. A few others believed that whatever matter was made of, it must be something that could not be destroyed. Atomic theory attempts to answer what all things are made of. It states that all matter is composed of extremely small particles called atoms. The word atom meant "indivisible" in Greek and was first used by Democritus, a Greek philosopher (Similar

    development of atomic theory, and made science changing discoveries that are still today quite impressive, even in comparison to modern day scientists. There are countless scientists involved in the evolution of atomic theory, but less than 50 have majorly impacted the way we view atomic theory today. Discovery and experimentation on the atom first began in the Greek Era with scientists as old as Democritus and Aristotle. Democritus was believed to be the first person to touch on the atomic theory. He stated

    The history of the atomic theory is thoroughly extensive. It had all started around 400 BCE when few people believed in an atomic theory, that atoms are building blocks. Democratic believed matter was made up of tiny particles. He called them atomos. Democratic is Leucippus’ most infamous pupil Later in history, the law of definite proportions was discovered. Two samples of given compounds are made of the same elements in exactly same proportions by mass regardless of the size or sources of the samples

    Emily Elliott Scientists who Contributed to Atomic Theory 20 September 20 What is Atomic Theory? Atomic theory is the theory that all matter is made up of tiny indivisible particles called atoms. This paper will discuss its beginnings and some of the scientists who made major contributions to how it is defined today. Background Since the earliest of times, scientists and philosophers have known that the universe is more than just what it appears to be, but instead there is a deeper, more

    The Atomic Theory The atomic theory is a fundamental scientific theory of the nature of matter, which states that matter is composed of discrete units called atoms, which came from the Greek word atomon, meaning ‘uncuttable’. This theory was based on the concept that any given item in the universe could be broken down using pico- and femtometer atomic/subatomic/alpha particles. If this idea had never been composed, science would have suffered as a result and many scientists would not have been

    History of Atomic Theory 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

    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
