Aluminum Atoms

corpuscleic number 13 Atoms Pre-AP Chemistry Mr. Vopatek Lab Report 2 Charlie Plunkett 3 October 2012 Charlie Plunkett Mr. Vopatek Pre-AP Chemistry 3 October 2012 Aluminum Atoms Purpose The social function of this science laboratory was to determine the thickness of a composition of componentic number 13 foil in atoms. Another purpose of this audition is to dress out how many aluminum atoms are red-hot up to create the foils thickness. Theory Daltons thermonuclear Theory plays a large part in this lab as the main points in his theory allows the lab to be successful. Dalton stated that all matter is made up of atoms. This proves that the aluminum is made up of individual atoms, allowing for measurement of the thickness. Dalton also embroil in his theory that atoms of the same element are identical. This prole that no atom in the aluminum foil would be diverse from another proving that there are no differences in measurement from atom to atom, and that the foil is pure aluminum. Rutherfords grand foil experiment gave us insight to the atom. Throughout the experiment, Rutherford seduce that because particles bounced off of the gold foil antitheticly, the atom must attain some empty space and some solid in the center. This allowed for progression into the field of looking into the atom.

Eventually the modern impersonate of the atom would come from this. The nuclear size of the atom is careful in AMUs or atomic mass units. This outset atomic weight basis was suggested by John Dalton in 1803. One gram equals 6×10²³ AMUs. The atomic potentiometer of the element are average masses, and they take into account th e different isotopes that exist. Without the! AMU, the lab wouldnt be possible because the mass of the atom would be unknown. The angstrom is the previously used measurement for atomic radius. The angstrom is equal to 1×10-10 meters. The angstrom has been surpassed by the picometer however which has a more accurate reading with 1 picometer equaling 1×10-12. The angstrom has lost popularity and...If you want to develop a full essay, order it on our website: OrderEssay.net
