Atomic Structure & Quantum Mechanics

Study Guidelines for Students

• Start with understanding Bohr’s model before moving to quantum mechanical model
• Practice writing electron configurations for elements 1-20 regularly
• Use mnemonic devices to remember orbital filling order (1s, 2s, 2p, 3s…)
• Draw diagrams to visualize atomic radius trends across periods and groups
• Relate quantum numbers to specific electron addresses in atoms
• Compare line spectra of different elements to understand emission spectra
• Solve problems on identifying elements from their electron configurations
• Review periodic trends regularly to build long-term memory
• Form study groups to discuss and explain concepts to peers
• Create flashcards for quantum numbers and their allowed values
