Common mistake
Misclassifying Element Blocks
Students often misclassify elements as s, p, d, or f block based on incorrect assumptions about their properties rather than their position in the periodic table.
To classify elements correctly, refer to their position in the periodic table. The block classification is determined by the highest energy sublevel that is being filled. For example, elements in Group 1 and 2 are s block, Groups 13-18 are p block, Transition metals are d block, and Lanthanides and Actinides are f block.
