Baryon Isovector Electric Properties and the Large N_c and Chiral Limits

A model independent calculation is given for the nucleon isovector electric charge radius which is valid in the limit $N_c\to \mathrm{\infty }$, $m_\pi \rightarrow 0$,$N_c m_\pi$ fixed. This expression reduces to that of the Skyrme model in the limit $N_c{m}_{\pi }\to \mathrm{\infty }$.
