Doubtly AI · Accepted Answer

Answer: four; s-block; p-block; d-block; metals; f-block. On the basis of electronic configuration, elements in the modern periodic table are classified into four blocks. Groups 1 and 2 elements are included in the s-block and all these elements are metals (except hydrogen). Group 13 to 18 elements are included in the p-block. This block contains metals, non-metals and metalloids. Group 3 to 12 elements are included in the d-block and all the elements are metals. The elements shown at the bottom of the periodic table, i.e. lanthanides and actinides, constitute the f-block and all these elements are metals.
