Aluminum Atoms
Purpose
The purpose of this lab was to determine the thickness of a composition of aluminum foil in atoms. Another purpose of this audition is to find out how many aluminum atoms are red-hot up to create the foils thickness.
Theory
Daltons nuclear 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 include in his theory that atoms of the same element are identical. This doer 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 sumptuous foil experiment gave us insight to the atom. Throughout the experiment, Rutherford realize that because particles bounced off of the gold foil differently, the atom must urinate some empty space and some solid in the center. This allowed for progression into the field of looking into the atom.



Eventually the modern portray of the atom would come from this.
The atomic size of the atom is metrical in AMUs or atomic mass units. This outgrowth atomic weight basis was suggested by John Dalton in 1803. One gram equals 6×10²³ AMUs. The atomic batch of the element are average masses, and they take into account the 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 micromicron however which has a more accurate reading with 1 picometer equaling 1×10-12. The angstrom has lost popularity and...If you want to formulate a full essay, order it on our website: Orderessay
