    02 Chemistry Study Material (SSC CHSL)

    🧪 SSC CHSL Chemistry Study Material – Easy Guide with Emojis Here’s a simple, emoji-filled summary of the key Chemistry concepts from your SSC CHSL PDF1: 🌌 Matter & Its States Matter is anything that has mass and takes up space (except: heat, light, electricity, sound, magnetism, vacuum, shadow). Particles of matter are tiny, have spaces between them, and are always moving (kinetic energy 💚). Intermolecular force: Strongest in solids 🧱, weaker in liquids 💧, weakest in gases 💚. States of Matter 🧱 Solid: Fixed shape & volume, particles packed tightly, not compressible. 💧 Liquid: No fixed shape, fixed volume, particles move more freely. 💚 Gas: No fixed shape or volume, particles move freely, highly compressible. 🌟 Plasma: Super-energized, ionized gas (found in stars, neon signs). ❄ Bose-Einstein Condensate: Super-cooled, low-density gas where atoms act as one quantum state. 🔬 Atoms & Molecules Atom: Smallest part of an element that can take part in a chemical reaction. Example: Hydrogen atom is the smallest. Atomic mass: Measured in atomic mass units (u), based on carbon-12. Molecule: Group of two or more atoms bonded together (can be same or different elements). Atomicity: Number of atoms in a molecule. Ion: Charged particle. Positive = Cation ➕ Negative = Anion ➖ ⚖ Laws of Chemistry Law of Conservation of Mass: Mass is neither created nor destroyed in a chemical reaction. Law of Constant Proportions: Elements in a compound are always in fixed ratios by mass. 🧑‍🔬 Atomic Models Dalton’s Atomic Theory: All matter is made of atoms. Atoms can’t be created/destroyed. Atoms of the same element are identical. Thomson’s Model: “Plum pudding” – electrons in a positive sphere. Rutherford’s Model: Tiny nucleus (positive), electrons revolve around it. Bohr’s Model: Electrons in energy levels (shells: K, L, M, N
). 🧩 Subatomic Particles Electron (e⁻): Discovered by J.J. Thomson, negative charge. Proton (p⁺): Discovered by Goldstein, positive charge. Neutron (n⁰): Discovered by Chadwick, neutral. 🧮 Key Atomic Terms Atomic Number (Z): Number of protons. Mass Number (A): Protons + Neutrons. Isotopes: Same atomic number, different mass (e.g., Hydrogen: Protium, Deuterium, Tritium). Isobars: Same mass number, different atomic number (e.g., Argon-40 & Calcium-40). Isotones: Same number of neutrons. 🧪 Chemical Formulae & Valency Chemical formula: Shows which elements and how many atoms are in a compound. Valency: Combining capacity of an element (number of electrons lost, gained, or shared). 🧬 Molecular Mass & Avogadro’s Number Molecular mass: Sum of atomic masses in a molecule (e.g., H₂O = 2×1 + 16 = 18u). Avogadro’s constant: $6.022 \times 10^{23}$ (number of atoms in 12g of carbon-12). 💡 Fun Facts & Exceptions Diffusion: Mixing of particles; fastest in gases, slowest in solids. Rubber band: Can stretch (solid with flexibility). Sponge: Solid but compressible due to air holes. Plasma: Found in stars, neon lights. BEC: Predicted by S.N. Bose & Einstein, at ultra-low temperatures. 📝 Quick Reference Table State Shape Volume Compressible Example 🧱 Solid Fixed Fixed No Ice, Iron 💧 Liquid No Fixed Slightly Water, Oil 💚 Gas No No Yes Oxygen, Steam 🌟 Plasma No No Yes Sun, Neon Signs ❄ BEC No No Yes Ultra-cold gases Use these emojis and points to quickly revise Chemistry for SSC CHSL!

Artificial preservatives 🧎: Prevent food spoilage by stopping microorganism growth (e.g., Sodium benzoate, sodium meta bisulphate). Flow stabilizers 💧: Maintain consistency. Binding substances 🪢: Hold ingredients together. Artificial sweeteners 🍬: Add sweetness without calories (e.g., Aspartame in cool drinks/ice-cream, Alitame is 2000x sweeter than sugar). Antioxidants 🛡: Prevent food oxidation/spoilage (e.g., BHT, BHA). Minerals & Vitamins 💊: Only vitamins have nutritional value. 🧎 Artificial Preservatives Stop food spoilage by preventing microorganism growth. Examples: Sodium benzoate, sodium meta bisulphate. 🍭 Artificial Sweeteners No calories, excreted via urine. Aspartame: Used in cool drinks and ice-creams.
