note the lewis structure H3O+. Highly electronegative atos often have a partial negative charge on them. negative formal charges, on the other hand, are not necessarily found on highly electronegative atoms. comment on the situation in this case. is the positive charge of hydronium ion on the least electronegativity atom? is this reasonable? is there a choice?
