This is the periodic table of the elements. Luis made a table of some of the elements and the charges of their ions from period 4. Element Charge K +2 Ca +2 Cr +2 or +3 Se −2 Br −1 According to information in the periodic table, what mistake did Luis make in his table? A The −2 charge for Se is incorrect, because Se is in group 17 which have charges of −1 when they form ions. B The +2 charge for K is incorrect, because K is in group 1 which have charges of +1 when they form ions. C The +2 charge for Cr is incorrect, because Cr is in group 1 which have charges of +1 when they form ions. D The −1 charge for Br is incorrect, because Br is in group 1 which have charges of −2 when they form ions.
