10-Day Revision Plan

Some Basic Concepts of Chemistry + Structure of Atom + Classification of Elements & Periodicity + Redox Reactions

---

Day 1 — Basic Concepts (Part 1)

• Importance of chemistry, physical quantities & SI units
• Precision, accuracy, significant figures
• Laws of chemical combination (conservation of mass, definite proportions, multiple proportions, reciprocal proportions, Gay Lussac's law)
• Dalton's atomic theory (recap)
• Practice: significant figure & unit conversion problems

Day 2 — Basic Concepts (Part 2)

• Atomic mass, molecular mass, formula mass
• Mole concept, Avogadro number
• Molar mass, percentage composition
• Empirical formula & molecular formula (numericals)
• Stoichiometry and stoichiometric calculations
• Limiting reagent problems
• Practice: 10–12 mole concept/stoichiometry numericals

Day 3 — Structure of Atom (Part 1)

• Discovery of electron, proton, neutron
• Thomson's, Rutherford's atomic models (and their limitations)
• Atomic number, mass number, isotopes, isobars
• Electromagnetic radiation, Planck's quantum theory
• Photoelectric effect
• Bohr's model of hydrogen atom + line spectrum of hydrogen

Day 4 — Structure of Atom (Part 2)

• Limitations of Bohr's model
• Dual behaviour of matter (de Broglie equation)
• Heisenberg's uncertainty principle
• Quantum mechanical model of atom (basic idea)
• Quantum numbers: n, l, m, s — meaning and allowed values
• Shapes of s, p, d orbitals
• Aufbau principle, Pauli exclusion principle, Hund's rule
• Electronic configuration of atoms (practice writing configs)

Day 5 — Full Revision: Basic Concepts + Structure of Atom

• Redo all numericals (mole concept + quantum numbers) without notes
• Self-test: 15 MCQs + 5 short answers (30 min, timed)
• List weak points for later review

Day 6 — Classification of Elements & Periodicity (Part 1)

• Need for classification, brief history (Döbereiner, Newlands, Mendeleev)
• Modern periodic law, present form of periodic table
• Nomenclature of elements with atomic number >100
• Electronic configurations and types of elements (s, p, d, f block)
• Periods and groups, valence electrons

Day 7 — Classification of Elements & Periodicity (Part 2)

• Periodic trends: atomic radius, ionic radius
• Ionization enthalpy, electron gain enthalpy, electronegativity
• Trends across periods and down groups (with reasons)
• Periodic trends in chemical reactivity
• Anomalous properties of second period elements (diagonal relationship)
• Practice: trend-comparison and reasoning-based questions

Day 8 — Redox Reactions

• Classical idea of oxidation-reduction
• Oxidation number concept — rules for assigning
• Types of redox reactions: combination, decomposition, displacement, disproportionation
• Balancing redox equations:
  • Oxidation number method
  • Half-reaction (ion-electron) method
• Redox reactions in terms of electron transfer
• Practice: balance 10–12 redox equations using both methods

Day 9 — Full Revision: Periodicity + Redox

• Redo periodic trend diagrams and redox balancing from memory
• Solve previous year/HOTS questions (mixed from both chapters)
• Quick recap table: element block | trend | reason
• Mark remaining doubts for Day 10

Day 10 — Mock Test + Final Touch-Up

• Full mock test (1–1.5 hrs): mix of all 4 chapters — MCQs, numericals, short & long answers
• Evaluate and revisit weak areas
• Rapid-fire recap:
  • Mole concept formulas
  • Quantum numbers & electronic configuration rules
  • Periodic trends (across period/down group)
  • Redox balancing steps
• Final one-page cheat sheet read-through (all 4 chapters)

Daily Tips

• Do at least 5–8 numericals daily (mole concept, redox balancing) — this chapter set is calculation-heavy.
• Keep a running "formula sheet" (mole formulas, quantum number rules, periodic trend summary).
• Use blank periodic table printouts to test yourself on trends without labels.
• Spend last 10 minutes each day writing electronic configurations of 5 random elements from memory.
