Demerits of Modern Periodic Table:
● The Long form of periodic table is demerit free as it has all the qualities what should be in a classification table. However, two main defects could be measured as:
● Position of Hydrogen is ambiguous as it resembles with both the alkali metals and halogen group, but is placed with alkali metals.The position of Lanthanides and Actinides are outside the main body which looks inappropriate.
