Noble Gases or Inert Gases (Helium, Neon, Argon, Krypton, Xenon, Radon) — stable electronic configurations. Radon is a radioactive noble gas not found commonly in the atmosphere. 3. Chemical Bonding and Reactions
This module is highly scoring, as SSC frequently asks about everyday acids and pH values. Sour taste. Turns blue litmus paper red. Releases hydrogen ions ( H+H raised to the positive power ) in water. Vinegar: Acetic acid Lemon/Orange: Citric acid Tomato: Oxalic acid Sour Milk/Curd: Lactic acid Ant sting: Methanoic (Formic) acid Tamarind: Tartaric acid Bitter taste and soapy feel. Turns red litmus paper blue. Releases hydroxide ions ( OH−OH raised to the negative power ) in water. Soluble bases are called Alkalis (e.g., The pH Scale Devised by Sorensen to measure acidity or alkalinity.
