I registered to this site just to thank Hermanntrude. Thank you so much. I recieve a oxyanions on a worksheet today . To be specific the ClO4- . And I thought I had lewis structures mastered, I had done hours and hours of homework. And my T.A said , this stuff is simple compared to the exam. Yah...... ? We didnt even over oxyanions or for that matter ions in lewis structure. Honestly it took alot of time for you to write that , and it was crystal clear. Thanks so much. No other websites explain this
