Dị ka free radicals (molecules nwere otu eletrọn), dibasic na polybasic (molecules nwere abụọ ma ọ bụ karịa otu electrons), triplet molecules (nwekwara otu electrons abụọ na molekụla orbital, ma ha dị nnọọ iche na nso nso a, e nwere ike dị ike. mmekọrịta magnetik n'etiti ibe ha, nke dị iche na isi okpukpu abụọ) na ihe ndị ọzọ.

    Ihe nwere otu elektrọn na-apụta na orbitals atomic, dị ka alkali metal atom, ion metal metal (gụnyere iron otu, palladium, na platinum otu ion, nke n'aka nke emejuwo 3d, 4d, 5d shells), obere metal metal ion (Ya na ya. shei 4f juru eju) na ndị ọzọ.
