Position of Hydrogen: Hydrogen was placed arbitrarily as it resembled both alkali metals and halogens, leading to ambiguity. • Isotopes: Mendeleev's table could not explain the placement of isotopes, which have the same chemical properties but different atomic masses. • Anomalous Pairs: Certain elements with higher atomic masses (e.g., Argon and Potassium) were placed before elements with lower atomic masses to maintain their chemical properties. • No Explanation for Trends: The table lacked a theoretical basis for periodic trends and why elements showed similar properties in groups. • Gaps in the Table: While Mendeleev predicted new elements, the table had several empty spaces for undiscovered ones, making it incomplete. • Position of Lanthanides and Actinides: These elements were not systematically placed within the table. • Class 11 Chemistry Demerits Of Mendeleev Periodic Table • Chemistry Class 11 • Demerits Of Mendeleev Periodic Table • Anomalies • Atomic Mass • Position of Isotopes • Hydrogen Placement • Unclassified Elements • Modern Periodic Table • Periodic Trends • Classification Errors • Transition Elements • Periodic Law Limitations • #PeriodicTable #MendeleevTable #ScienceFacts #ChemistryClass11 #LearnChemistry #PeriodicDemerits #ScienceEducation #ChemistrySimplified #StudentLife #ScienceExplained
