Study more about Physical properties, Chemical properties, General reaction, Thermal stability of. The atomic size of dblock elements decreases from Sc to Zn due to increase in nuclear charge. Their atomic sizes are smaller than that of sblock. dblock Transition metals of element groups 312. fblock Inner transition elements, usually the lanthanide and actinide series, including lanthanum and actinium. gblock (proposed) Would be expected to include element with atomic numbers higher than 118. Charles Janet first applied the term (in French). There is an approximate correspondence between this nomenclature of blocks, based on electronic configuration, and groupings of elements based on chemical properties. The sblock and pblock together are usually considered as the main group elements, the dblock corresponds to the transition metals, and the fblock are the lanthanides and the actinides. The highly electropositive sblock elements combine with nitrogen in the solid state to form some of the most ionic nitride compounds known. The sblock in the periodic table of elements occupies the alkali metals and alkaline earth metals, also known as groups 1 and 2.
