Complete the table for ion charge based upon their losing or gaining electrons in the outer shell. (use the periodic table as necessary.) group most likely ionic charge # of valence electrons i +1 ii +2 iii +3 iv +4 or -4 v -3 vi -2 vii -1 viii 0

Explanation:

Group           Most Likely Ionic Charge               Number of Valence Electrons

   I                                 +1                                                           1

   II                                 +2                                                         2

   III                                +3                                                          3

   IV                           +4 or -4                                                     4

   V                                  -3                                                         5

   VI                                 -2                                                         6

  VII                                 -1                                                          7

  VIII                                 0                                                          8

For elements in group IV and above, their ionic charge is (8-number of their valence electrons.)

that tool would be a compass

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
