Believed everything in the universe was made up of atoms, which were microscopic and indestructible. Stated atoms are solid, homogeneous, indivisible, and unchangeable.]]> 2018-10-08 12:13:48 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290250831 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290253324 1803                England
stated:
1. All mater is made of atoms
2. Atoms are invisible & indestructible
3. Compounds are formed by a combination of 2 or more atoms 
All atoms of an element were identical, different elements had atoms of differing size and mass]]> 2018-10-08 12:19:55 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290253324 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290254887 1869                     Russia
Most important contributor to the development of the periodic table. He believed that elements should be organized into rows according to their atomic mass and into columns based on chemical and physical properties.

He created the electrons theory which stated that electrons flow and can be defined as a moving charge. Created the plum pudding model which showed the nucleus in order to include the electron into the atomic model. ]]> 2018-10-08 12:28:55 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290256848 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290259919 1911        New Zealand
Ernest was the first to discover that atoms have a small charged nucleus surrounded by largely empty space. He created the Rutherford model to demonstrate and show the atom with a nucleus.]]> 2018-10-08 12:36:47 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290259919 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290262094 1922                Denmark
Came up with the Atomic Theory:
This stated that matter is indivisible and made up of tiny particles. Also created the Bohr model which shows the atom as a small, positively charged nucleus surrounded by orbiting electrons.

Erwin took the bohr model one step further by making it even more advanced. Using mathematical equations to describe the likelihood of finding an electron in a certain position. This model is known as the quantum model.]]> 2018-10-08 12:49:38 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/290266626 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525340 2018-10-11 01:22:53 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525340 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525564 2018-10-11 01:23:57 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525564 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525702 2018-10-11 01:24:41 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525702 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525829 2018-10-11 01:25:23 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525829 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525921 2018-10-11 01:25:46 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291525921 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291526093 2018-10-11 01:26:38 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291526093 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291526296 2018-10-11 01:27:42 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291526296 pattersonkyndram https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291526596 2018-10-11 01:28:53 UTC https://padlet.com/pattersonkyndram/m5x02ya8frn/wish/291526596
