scientist called Democritus‚ who developed the idea that everything is made up of smaller things‚ which he named atomos. Due to his revelation in science many people consider him to be the ’Father of modern science’‚ although his work wasn’t solely basedon science he was able to use the work of philosophers such as Leucippus and Anaxagoras. Democritus also believed that between atoms there was nothing but empty space‚ that they are indestructible and they are always in motion. Democritus also believed

Which of the following statements is part of Democritus’s theory about atoms? a. Atoms are the smallest piece of matter. 3. We know that Democritus was right about atoms. So why did people ignore Democritus’s ideas for such a long time? Democritus’s ideas were ignored for a long time because he had no proof of the atoms existence.

Pineda‚ Carlitos Miguel Ponce M. January 9‚ 2013 AIT2A Natural Science 12 ATOM DEVELOPMENT WITH SCIENTISTS INVOLVED 400 B.C. - Democritus’ atomic theory posited that all matter is made up small indestructible units he called atoms. Democritus expanded the idea to state that matter was composed of small particles called "atoms" that could be divided no further. These atoms were all composed of the same primary matter with the only differences between them being their size‚ shape

Matter is made up of atoms and molecules. Atoms and molecules are always in motion because energy. Energy forces them to contact into each other or vibrate back and forth. When this happens molecules and atoms

theorized by a man named Democritus of Abdera‚ Thrace in between c.a 460 BC - ca. 370 B.C. Atom is derived from the Greek word “atomos” ‚ which means to be uncuttable. He had a theory that everything is composed of “atoms”‚ which he believed that these minuscule objects are indivisible‚ indestructible and have and always been in motion‚ had a void that exists between atoms‚ they are solid‚ homogeneous‚ and differ in size‚ shape‚ mass‚ position‚ arrangement‚ etc. Democritus identified all of these

The Pre-Socratic Philosophers | "Pre-Socratic" is the expression commonly used to describe those Greek thinkers who lived and wrote between 600 and 400 B.C. It was the Pre-Socratics who attempted to find universal principles which would explain the natural world from its origins to man’s place in it. Although Socrates died in 399 B.C.‚ the term "Pre-Socratic" indicates not so much a chronological limit‚ but rather an outlook or range of interests‚ an outlook attacked by both Protagoras (a Sophist)

matter around us is made tiny subatomic units called atom—the word atom originates from the Greek word atomos‚ which in Greek virtually means “indivisible” (Stanford Encyclopedia of Philosophy: Ancient Atomism). This idea was actually inherited by Democritus is widely given credit for this idea (Boorse 1). However‚ his theory would be rivaled by famous Greek philosopher Aristotle‚ who claimed that all matter consisted of four elements: earth‚ air‚ water and fire. [See figure 1.1] Aristotle also believed

Models of the Atom: a Historical Perspective John Dalton Early Greek Theories • 400 B.C. - Democritus thought matter could not be divided indefinitely. • This led to the idea of atoms in a void. fire Democritus • 1800 -Dalton proposed a modern atomic model based on experimentation not on pure reason. All matter is made of atoms. Atoms of an element are identical. Each element has different atoms. Atoms of different elements combine in constant ratios to form compounds. • Atoms are rearranged
