But sadly a man by the name of eri stoddles disagrees with democrutis.

Then john included that at the various compound were combination of atoms of different elements each of a particular size of mass that cannot be create or destroyed.]]> 2022-10-14 04:10:55 UTC https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2339805250 J.J Thomson 1856 - 1940 AD franco0707 https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2341763621 Then after john Dalton a man by the name of J.J Thomson who discovered the electron which we called it the chocolate chip cookie of a atom. J.J Thomson showed Atoms as a uniformly packed sphere of positive matters filled with negatively charged electrons.]]> 2022-10-16 10:24:55 UTC https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2341763621 Ernest Rutherford 1871 - 1937 AD franco0707 https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2341767458 After J.J Thomson we got Ernest Rutherford who would become known as the father of the nuclear age while studying the effects of x-rays on gasses Ernest decided to investigate on atoms closely by shooting more positively charged alpha particles at a sheet of gold foil. But some of the particles penetrate through the gold foil but some instead deflect. ]]> 2022-10-16 10:34:23 UTC https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2341767458 Niels Bohr 1885 - 1962 AD franco0707 https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2341770554 Then next after Ernest we got Niels Bohr he said that the electrons orbit the nucleus at fixed energy's and distances able to jump from one level to another but not to exist in a space between. But rather than being discrete particles electrons simultaneously behaved like waves. ]]> 2022-10-16 10:41:13 UTC https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2341770554 Werner Heisenberg 1901 - 1976 AD franco0707 https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2341772634 Then next we got Werner Heisenberg who said that it was impossible to determine both exact position and speed of electron's as they move around the atom.]]> 2022-10-16 10:46:07 UTC https://padlet.com/franco0707/l81llzzd7wa0h0b1/wish/2341772634
