- Statement 1:The 4f - and 5f - inner transition series of elements are placed separately at the bottom of the Modem periodic table Statement 2: (i) Position of f -block elements prevents the undue expansion of the Modem periodic table, i.e., maintains its structure (ii) Position of f-block elements preserves the principle of classification by keeping elements with similar properties in a single column
Q.
Statement 1:The - and - inner transition series of elements are placed separately at the bottom of the Modem periodic table
Statement 2: (i) Position of -block elements prevents the undue expansion of the Modem periodic table, i.e., maintains its structure
(ii) Position of -block elements preserves the principle of classification by keeping elements with similar properties in a single column
Solution:
