All elements are composed of tiny indivisible particles called atoms.
2.) Atoms of the same element are identical. The atoms of any one element are different from those of any other element. 
3.) Atoms of different elements can physically mix together or can chemically combine in simple whole-number ratios to form compounds.
4.) Chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction. ]]> 2017-10-09 19:13:49 UTC https://padlet.com/PowersM186/hgribh7tjkns/wish/195360741 PowersM186 https://padlet.com/PowersM186/hgribh7tjkns/wish/195362843 This is showing that electrons move in specific circular paths(orbits) around it's nucleus. ]]> 2017-10-09 19:21:48 UTC https://padlet.com/PowersM186/hgribh7tjkns/wish/195362843 PowersM186 https://padlet.com/PowersM186/hgribh7tjkns/wish/195364952 In this model the protons and neutrons are found inside of the nucleus and the electrons are around it in mostly empty space.]]> 2017-10-09 19:30:08 UTC https://padlet.com/PowersM186/hgribh7tjkns/wish/195364952 PowersM186 https://padlet.com/PowersM186/hgribh7tjkns/wish/195366449 This comes from the mathematical solutions to the Schrodinger equation. It determines the allowed energies an electron can have and how likely it is to find the electron in various locations around the nucleus. ]]> 2017-10-09 19:36:11 UTC https://padlet.com/PowersM186/hgribh7tjkns/wish/195366449 PowersM186 https://padlet.com/PowersM186/hgribh7tjkns/wish/195368191 J.J Thomson discovers the electron and thinks that they will look like embedded circles in a sphere. ]]> 2017-10-09 19:41:16 UTC https://padlet.com/PowersM186/hgribh7tjkns/wish/195368191
