Democritus

Another philosopher, Leucippus studied with Zeno of Elea. He is most famous for his idea of the atom. He believed that everything on earth was made up of tiny atoms, “Even the soul is made up of atoms”(pg 7). The last philosopher talked about was Democritus, one of Leucippus’ students. He developed Leucippus’ idea of atoms into a solid…

The first atomic model was introduced by an English chemist, physicist, and meteorologist named John Dalton. John Dalton had reintroduced the idea of the atom that had once been a theory of a Greek scientist named Democritus. However, unlike Democritus, Dalton was able to prove the existence of atoms. Through many experiments, Dalton came up with a list of properties, that he thought, all atoms shared. Each element is composed of atoms Atoms are tiny, featureless spheres All atoms of same…

John Dalton was a great chemist who lived from September 6, 1766 to July 26, 1844. One interesting thing about John Dalton was that he was color blind but it did not stop him from doing anything! He was a man who loved to study meteorology and do many different experiments that have to do with many different gasses that are under controlled conditions. He identified many different laws, postulates, etc. One of which were his four postulates over the atom. John Dalton’s Postulates include:…

Tiny particles react with each other every second to sustain our daily lives. These particles are called atoms, and they are the most basic and indivisible units of matter. They retain their identity through chemical reactions, yet they are so small that even the strongest microscope cannot detect them. The reasoning behind atomic reactions intrigued many intellectuals. To understand more about this concept, they had to comprehend the compositions of these particles. Although the scientist and…

– equation (2 gives info on location of electron in terms of probability density - wave functions are called orbitals – [pic], where E is energy, e2 is electric potential, r is orbital radius and h is Planck’s constant 1925 Wolfgang Pauli – each orbital has only 2 electrons is now explained due to direction of spin of electrons. Spinning electrons create magnetic field. Only 2 electrons of opposite spin in an orbital referred to as Pauli exclusion principle Hund’s rule – half fill…

People find out new things about the world every day. Scientific findings are almost never final. Experiments can verify or shatter what we perceive as facts of life. Atoms are an example of this. Thinkers and scientists from throughout time have been theorizing and experimenting to find out what an atom is made of. The structure of an atom is very complex, and because of that, its known structure has drastically changed over time. What we know as an atom today is composed of many subatomic…

The Atomic Theory The atomic theory serves as the basic foundation for the study of matter; it is of major importance to the study of Chemistry. The atomic theory has an interesting and lengthy history that shall be discussed. Furthermore, it has been perfected and discussed by many chemists over a number of years; all of their brilliant minds put together into one. There have been drastic changes to the atomic structure in modern times, proving we still do not know everything. Technology…

that the Atom itself was Fundamental and that nothing was smaller. The theory was first proposed by the Greek philosopher Democritus. He named the atom the Atomon, which meant indivisible. His famous quote is “by convention sweet, but in reality atoms and void". He proposed this in the Greek era, specifically around 400 BCE. Later on in 1704, Isaac Newton looked at Democritus 's work. He believed that atoms were indestructible. He also believed that they all differed in both shape and size. He…

Hanh Annie Vu PSYC 511 – Psychology Concepts Dr. David Perkins October 27, 2017 Mid-term exam Question 1 Since the beginning of time, philosophers and scientists have been investigating the composition of everything in the universe. While monists attempt to explain everything in terms of one reality – either physical matter or mental activity, dualists believe in the existence of both (Hergenhan & Henley, 2013). The mind-body question then came into existence to investigate the relationship…

something would have to move to where something is not, which something is always there according to him. Space is not true either then because nothing is “empty”. It either has air which is not space or an actual thing or object. On the other hand, Democritus believes everything is made of atoms and the only difference is within the size, position, motion, shape and distance from one another. The atoms move around freely which means there cannot be an up or down. So apparent things must be…
