The D block elements, transition metals, and their properties were discussed, focusing on electron configurations, atomic and ionic sizes, stability, oxidation states, and reactivity trends, stressing the importance of a thorough understanding for competitive exams.
Insights
- The D&F Block Elements chapter in the Buniyaad Series is vital for board exams, JE, and NEET preparations, with detailed notes provided for retention.
- Transition elements are defined by incomplete D sub shells in their neutral or ionic states, occupying the middle section of the periodic table.
- Mnemonics aid in remembering the series of transition elements like 3D, 4D, and 5D, emphasizing the importance of understanding electron configurations for elements like copper and palladium.
- The properties of transition elements, including metallic characteristics, melting points, and atomic sizes, are influenced by factors like unpaired electrons and interatomic metallic bonding.
- The relationship between the number of unpaired electrons and melting points of transition metals is highlighted, with a focus on the impact of interatomic metallic bonding and shielding effects.
- Actinoids consist of 14 elements from Th to Lr, with atomic numbers ranging from 89 to 103, featuring complex electron configurations, oxidation states, and applications in various industries.
