Environmental Problems in our Lifetime, The sun and our atmosphere. 3 02 Atomic Evolution, January 10, Relationship between CO2 and Global Temperature. Atmospheric CO2 and Global Temperature, 3 02 Atomic Evolution. January 10, Charles David Keeling An Analytical Chemist. Charles David Keeling, 3 02 Atomic Evolution, January 10.
Idea of the Atom, How did man come up, with the idea of the. It took 2400, years from when it, was conceived to. experimental, evidence prove of, 3 02 Atomic Evolution. January 10, History of Chemistry and development, of the atomic model. History of Atomic Structure, The timeline of the progression of the development of the.
Modern Atomic theory, Atomic Theory Timeline, Empedocles J Proust. A Lavoisier, Democritus, Zeno Aristotle Democritus Boyle Lavoisier Dalton. 5 0 0 2 5 0 0 250 500 750 1000 1250 1500 1750 2000. 3 02 Atomic Evolution, January 10, Matter according to Greek Philosophers. 492 375 BC Empedocles supported by Aristotle, Earth Air Fire Water. 400 BC Zeno also supported by Aristotle, Matter can be infinitely divided.
400 BC Leucippus, 470 375 BC Democritus student of Leucippus. Proposed the idea of the atom, Matter indivisible particles called atoms. Atheistic Belief, 3 02 Atomic Evolution, January 10. Next 2000 Years, Alchemy pseudo science lead into gold. experiments black magic took detailed notes, lab notebook conceived Systematic metallurgy.
extracted metals from ore, Roger Bacon 1214 1292 An. English and alchemist Bacon, became known as the founder of. experimental science He believed, that doing experiments for. yourself rather than just accepting, what other people tell you was the. way to learn about nature His, most important work was the Opus.
Matus in what he wrote about the, scientific method of learning He. did many experiment which showed, how rainbow are made by the. effect of water drops on sunlight, and how lenses could be used to. help people with weak sight, Pierre Gassendi 1600 Priest. Philosopher and scientist that, modified the original hypothesis of.
Leuccipus and stated all atoms, 3 02 Atomic Evolution. created by God, January 10, Atomic Structure Revolution. 1500 Robert Boyle The Skeptical Chemist, He performed detailed experiment with gases this. initiated the break down of the Greek s model of matter. 1700 Antoine Lavoisier, Father of modern chemistry. Law of conservation of mass, He made very careful measurements and concluded.
that mass is neither created nor destroyed The, thought at the time was then when a substance was. burned the ashes were lighter than the starting, material but Lavoisier did the experiment in an. enclosed container and determined that the mass did. not change Subsequent experiments with other, reactions was consistent with the conservation of. mass findings, 3 02 Atomic Evolution, January 10, 1790 1800 Joseph Proust. Law of definite proportion or Law of constant, composition A given compound always contain exactly.
the same proportion of elements by mass, i e H2O 2 16 or H O 1 8 by mass always true. whether there is 18 g or 139 g H2O, For H2O2 2 32 the H O is 1 g H 16 g O. In other words, Water found in SD or the Arctic or Jupiter s moon. will all have 1 g hydrogen to 8 g oxygen ratios, Likewise glucose found in sugar cane or sweet beets. have 6 g carbon to 1 g hydrogen to 8 gram oxygen, ratios 12 x 6 C 1 x 12 H 16 x 6 O i e The.
relative numbers and kinds of atoms are constant, 3 02 Atomic Evolution. January 10, 1800 John Dalton, J Dalton Founder of the Modern Atomic Theory. Law of Multiple proportion When two elements form a series of. compounds the ratio of the masses of the element that combine with 1. gram of the first element can be reduce to small whole numbers. Example Mass of nitrogen that combines with 1 0 gram of oxygen. Compound A 1 750 g g A B 1 750 0 8760 2 1, Compound B 0 8750 g g B C 0 8760 0 4375 2 1. Compound C 0 4375 g g A C 1 750 0 4375 4 1, Compounds consist of. atoms which, combines in whole, number ratios, NO2 g N1 2 O.
3 02 Atomic Evolution, January 10, 1808 Dalton s Atomic Theory. A new system of Chemical, Philosophy, All matter is made of atom. In a chemical reaction atoms are neither, created or destroyed but only arranged. differently, Atoms of the same element are identical. Compounds are formed from two or more, atoms Atoms combine in simple whole.
number ratios to form compounds, 3 02 Atomic Evolution. January 10, what s next, Around this period the model of the atom. was gaining acceptance by scientist, Questions still unanswered. What is an atom, How is it put together, What are the parts of an atom. 3 02 Atomic Evolution, January 10, Contributions to the Modern Atomic Theory.
