Recently, charge radii and ground-state electromagnetic moments of Li and Be isotopes were measured precisely. We have performed large-scale ab initio no-core shell model calculations for these isotopes using high-precision nucleon-nucleon potentials. Our computed charge radii, quadrupole and magnetic-dipole moments are in a good agreement with the measurements with the exception of the {sup 11}Li charge radius. The overall trends of all observables are well reproduced. The magnetic moments are in particular well described. Also, we are able to reproduce the small magnitude of the {sup 6}Li quadrupole moment and with the CD-Bonn NN potential also its correct sign.
