Naming the following ions in either their English common names or IUPAC systematic names: (a)S^2- (b)Cu^+ (c)Mg^2+ (d)Fe^3+ (e)NH4^+ (f)CN^- (g)HCO3^- (h)SO4^2- 3. Naming the following compounds in either their English common names or IUPAC systematic names: (a) Ba(MnO4)2 (b) MgO (c) HClO4 (d) KNO2 (e) CH3COOH (f) NaH2PO4 (g) Fe(OH)3 (h) HNO3 (i) AgNO3 (j)NaHCO3 4. In assigning the ground state electronic configuration for atoms or monatiomic ions, one usually follows the so-called building-up principle (usually called Aufbau principle). This principle is composed of three guidelines or rules. Describe the building-up principle. 5. Write the electron configuration of the following atoms or ions using both the complete and the shorthand notations, and indicating which electrons are the valence electons (the number inside the bracket is the atomic number of the element): (a) Na(11) (b) Cl(17) (c) Ca(20) (d)Br^1- (anion,35) (e) N (7) (f) S^2- (anion, 16) (g) Al^3+ (cation, 13) 6. In describing the spatial behavior of the electron in the hydrogen atom, one would encounter three quantum numbers which are corresponding to the three degrees of spatial freedom of the electron: the principle quantum number, the azimuthal quantum number (or the orbital angular momentum quantum number), and the magnetic quantum number. What are the physical meanings for these quantum number and also their allowed values in the case of the hydrogen atom. 7. (a) An archeologist finds a goblet, weighing 1.62 kg, which he believes to be made of pure gold. When 1350 cal of heat are added to the goblet, the temperature increase by 7.8。C. Calculate the specific heat of the gobelt. Is it made of gold? Explain. (The specific heat of gold is 0.031 cal/(g。C)) (b) In another test, the archeologist determines that the volume of the goblet is 205 mL. Calculate the density of the goblet and compare it to the density of gold (19.3 g/mL), lead (11.4 g/mL), and iron (7.86 g/mL). What is the goblet probably made of? 8. What is the density of lithium metal (in g/cm^3) if a cylinder wire with a diameter of 2.40 mm and a length of 15.0 cm has a mass of 0.3624g? --
