Question

DA LIUDIC I. Given the Lewis electron dot symbols below, circle those that have the same valence electron configuration (in the same Group). Ne: K Ca • Seº • Sn. I. . Ge. B. (Note: this is the one and only time we will consider the elements as Lewis electron dot symbols individually... you will NOT draw these and then combine them to find the Lewis dot structure for molecules (below)... ever! If you do not know what I mean, please ask me (after class or in my office. Follow the rules given in class / on my webpage (under Gen Chem I worie → Lewis dot procedure))) II. a. Draw the best Lewis dot structures of the following using the methods learned in class and also on the on-line study sheets). b. Show all lone-pair electrons and the formal charge on each atom if it is not zero. Show all work (emulate what I show on my slides- every step! 1) Li', an unexpected anion for the species 2) Holy close cation Batman! NeAr (https://www.liveabout.com/robins-oddest-holy-exclamations-from-the-batman-tv-series-3896999) 3) SiH4, some speculate that life on other planets could have molecules like this (Dr. Brosius thinks it not so likely)
