The electronic structure of the ground state and some excited states of neutral atoms with the nuclear charge numbers 1<~Z<~10 and their singly positive ions are investigated by means of our two-dimensional mesh Hartree-Fock method for strong magnetic fields 0.5<~\ensuremathγ<~10000. For \ensuremathγ=10000 the ground-state configurations of all the atoms and ions considered are given by fully spin-polarized configurations of single-electron orbitals with magnetic quantum numbers ranging from m=0 to m=\ensuremath-N+1, where N is the number of the electrons. Focusing on the fully spin-polarized situation, we provide critical values of the magnetic-field strength for which crossovers with respect to the spatial symmetries of the ground state take place. It is found that the neutral atoms and singly charged positive ions with 2<~Z<~5 have one fully spin-polarized ground-state configuration, whereas for 6<~Z<~10 one intermediate fully spin-polarized configuration with an orbital of 2p0 type occurs.
