(470 B.C.)
Credited with inventing the concept of the atom. -
(1743-1794)
First to look at the elements collectively. -
(1766-1844)
Created atomic theory. -
Mass is neither created or destroyed.
-
Atoms in different elements have different wieghts.
-
(1834-1907)
Created first periodic table. -
(1885-1962)
developed the explaination of the atomic structure. -
(1856-1940)
Discovered the electron, first to suggest the atom was spherical. -
(1868-1953)
determined the electronic charge of an element. -
(1871-1937)
Described the atom as having a nucleus surrounded by orbitting electrons. -
(1887-1961)
electrons aren't distributed but are orbital. -
(1887-1915)
developed the application of x-rays to study atomic structure. -
(1891-1974)
Proved the existence of nuetrons. -
Created by Ferdinand Bruan
-
Created by J.J. Thomson.
-
expiremented by Ernest Rutherford
-
shows the probable locations of an atom
-
All of the positive charges are crammed into the nucleus, all the others lay outside of the nucleus.
-
protons and nuetrons are densly compacted in a nucleus.
-
Created by Erwin Schrodinger,, shows that electrons don't have set orbits but have random motions.
