The minimal-energy B=6 solution of the Skyrme model is a static soliton with D4d symmetry. The symmetries of the solution imply that the quantum numbers of the ground state are the same as those of the lithium-6 nucleus. This identification is considered further by obtaining expressions for the mean charge radius and quadrupole moment, dependent only on the Skyrme model parameters e (a dimensionless constant) and F_\ensuremathπ (the pion decay constant). The optimal values of these parameters have often been deliberated upon, and we propose, for B>2, changing them from those which are most commonly accepted. We obtain specific values for these parameters for B=6, by matching with properties of the lithium-6 nucleus. We find further support for the new values by reconsidering the \ensuremathα-particle and deuteron as quantized B=4 and B=2 Skyrmions.
