Based on past SSC question trends, here are the core areas you must focus on: Chemical Bonding & Reactions Periodic Table & Periodic Properties Acids, Bases, and Salts Metals, Non-Metals, and Metallurgy Organic Chemistry & Everyday Chemistry Environmental Chemistry 2. Detailed Chemistry Notes (Topic-Wise) A. Atomic Structure & Atomic Theory The atom is the smallest unit of matter. Subatomic Particles: Electron ( e−e raised to the negative power ): Discovered by J.J. Thomson. Negatively charged. Proton ( p+p raised to the positive power ): Discovered by E. Rutherford. Positively charged. Neutron ( n0n to the 0 power ): Discovered by J. Chadwick. Neutral. Atomic Number ( ): Number of protons ( Mass Number ( ): Sum of protons and neutrons ( Isotopes: Same atomic number, different mass number (e.g., Isobars: Same mass number, different atomic number (e.g., B.
