History of an Atom by https://padlet.com/203120/lt891el23uts By Lindy and Tyler en-us 2016-11-10 18:14:10 UTC 2016-11-14 17:55:02 UTC hello@padlet.com Democritus: Greek Model 400 BC 203120 https://padlet.com/203120/lt891el23uts/wish/136838194 After searching for the description of matter he wanted to know if matter could be divided into smaller pieces forever, or if there was a limit. He named the smallest piece of matter " atomos" (not to be cut). Atoms were infinite in numbers. ]]> 2016-11-10 18:25:42 UTC https://padlet.com/203120/lt891el23uts/wish/136838194 Rutherford's Model 203805 https://padlet.com/203120/lt891el23uts/wish/136838822

All positive charges are found in the nucleus.All of the negative charges are found on the outside of the nucleus.Rutherford created the Gold Foil experiment which led to the anticipation of the Alpha particles bouncing back from the gold foil rather than entering straight through the foil.]]> 2016-11-10 18:27:00 UTC https://padlet.com/203120/lt891el23uts/wish/136838822 (From presenation)  203120 https://padlet.com/203120/lt891el23uts/wish/136840167 2016-11-10 18:30:02 UTC https://padlet.com/203120/lt891el23uts/wish/136840167 Aristotle's 4 elements 203120 https://padlet.com/203120/lt891el23uts/wish/136840742 Believe in the earth, water, air, and fire nature in matter.

All elements are composed of atoms. If the atoms are of the same element they are exactly alike. ]]> 2016-11-10 18:36:03 UTC https://padlet.com/203120/lt891el23uts/wish/136842519 Bohr Model 203805 https://padlet.com/203120/lt891el23uts/wish/137064908

The main purpose of the model is to describe the different properties that are being associated with electrons in different atomic settings.Bohr also stated that the model of a small atom contained a small mostly positive charged nucleus which is then orbited by the different various amounts of negatively charged electrons.

He called the electrons "corpuscles". Since there were negatively charged particles he thought there had to be positively charged ones as well. ]]> 2016-11-11 18:02:53 UTC https://padlet.com/203120/lt891el23uts/wish/137065349 https://goo.gl/vxZDh5 203120 https://padlet.com/203120/lt891el23uts/wish/137066957

It was hypothesized that electrons could only be at certain types of energy levels.Theses energy levels are now to be called orbit energy levels.So electrons can contain orbital levels.]]> 2016-11-11 18:18:43 UTC https://padlet.com/203120/lt891el23uts/wish/137068854 203120 https://padlet.com/203120/lt891el23uts/wish/137072224 https://goo.gl/7m2EQg]]> 2016-11-11 18:34:18 UTC https://padlet.com/203120/lt891el23uts/wish/137072224
