In this work, we present the elastic electron scattering longitudinal form factors of A≤10 nuclei computed in a variational Monte Carlo approach. We employ the Norfolk family of local chiral interactions and a consistent electromagnetic charge operator. Our calculations are compared both to data and past theoretical evaluations. This work represents, to our knowledge, the first exact many-body calculation of longitudinal form factors in the 7≤A≤10 mass range. Finally, we identify 9Be and 10B as candidate targets for renewed experimental interest, as they exhibit the potential to provide more stringent constraints on the theoretical models.
