Resonance Structure에서 + 하고 - 가 있던데
NO3에서 왜 6개 electron 가지고 있는 oxygen은 -고
어떤 compound에는 가운데 element가 왜 + 갖고 있는지 모르겠네요 ;;
왜 그런건지 좀 설명해주세요~!
The charges of the atoms on the resonance structure are determined by the electronegativity. For nitrate ion, the electronegativity value of Oxygen is 3.5 and nitrogen is 3.0. Therefore, oxygen has the partially negative charge.
