  1. Assume you have an atom of magnesium and an ion of magnesium. Draw the orbital diagram and electron configuration for both magnesium and its ion. • Assume you have a molecule of water. Show the number of valence electrons, draw the VSEPR diagram, give the bond angle and shape. • Does it sink or float? If the density of water is 1 g/cm3 determine if the following objects will sink or float in water. Aluminum: m = 5g, V=2.5cm3 Milk: m =4g, V=3.88cm3Cork: m=0.40g, V=.50cm3show your work! • Is the data for each student accurate, precise, both, or neither. Determine the percent error for each students average data to help make your decision. The accepted value is 2.71cm • Write, classify, and balance the following equation Ammonium Phosphate(aq) + Chromium (III) bromide(aq)  ammonium bromide (aq) + Chromium(III) phosphate(s) Aluminum(s) + copper(I) chloride(aq)  aluminum chloride(aq) + copper(s)
