Question

Given below are two statements : Statement (I) : The 4f series of elements are placed separately in the Periodic table to preserve the principle of classification. Statement (II) : s-block elements can be found in pure form in nature. In the light of the above statements, choose the most appropriate answer from the options given below :

Accepted Answer

Statement I is true but Statement II is false. Statement I is correct because the 4f series, known as the lanthanides, are placed separately to maintain clarity in the periodic table's structure. Statement II is false as s-block elements, particularly alkali metals, are highly reactive and rarely found in pure form in nature.
