The charge form factor of ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ in the $q^2$ range of 0 to 7 ${\mathrm{fm}}^{-2\mathrm{}}$ is calculated with a single-channel $t+\alpha$ resonating-group wave function which is fully antisymmetric and treats correctly the motion of the total center of mass. Both $C0\mathrm{}$ and $C2\mathrm{}$ contributions are taken into account, and proton and neutron distributions are separately considered. With no adjustable parameters in the calculation, the result obtained shows that a good agreement between theory and experiment can be achieved. The calculated rms charge radius and spectroscopic quadrupole moment are equal to 2.44 fm and - 3.70 ${\mathrm{fm}}^2$, respectively, which agree very well with empirically determined values.
