Keep a list of chemical names and formulas (like Plaster of Paris or Epsom Salt).
Latent Heat: Heat required to change the state without changing temperature. 2. Atomic Structure Understanding the building blocks of matter is crucial. Proton (discovered by Ernest Rutherford/Goldstein). Electron (J.J. Thomson). Neutron (James Chadwick). Atomic Terms: Atomic Number (Z): Number of protons. Mass Number (A): Protons + Neutrons.
Stick to Class 9 and 10 NCERT Science books for the core concepts. chemistry notes ssc
Matter is anything that has mass and occupies space. SSC frequently asks about phase changes.
SSC often repeats questions on ores, alloys, and acids. Keep a list of chemical names and formulas
