Explain how the elements are classified into s, p, d and f- block elements in the periodic table and give the advantage of this kind of classification.
Answer :
Classification of elements
i. The s-block contains alkali metals (period 1) and alkaline earth metals (period 2).
ii. The p-block (period 13- 18) contains metals, non- metals and metalloids.
iii. The d-block (period 3-12) contains transition metals.
iv. The f-block placed separately at the bottom of the table contains lanthanides and actinides.
