			Worksheet # 8 Quarter 1 Packet 5
	Chart showing mass of one atom   Element             Symbol              Atomic #            Atomic Mass        Mass of One Atom Aluminum               Al                        13                  26.981539          4.481 x 10^-23 g/atom of Al Barium Calcium Carbon Chlorine Copper Fluorine Gold Helium Hydrogen Iodine Iron Lead Lithium Magnesium Mercury Nitrogen Oxygen Phosphorus Potassium Silver Sodium Sulfur Uranium Zinc   Set your problems up like this... (26.981539amu)/(1 atom of Al) X (1g )/(( 6.022 x 10^23amu ) = 2.6981539x10^1 g/atom of Al = .4481x10^-22 g/atom of Al= 4.481x10^-23  g/atom of Al
		After completing the chart, determine the number of protons and neutrons in one atom of each of the above 25 elements.
