Formed by cooling a gas of extremely low density to super-low temperatures close to absolute zero. Chemical Classification
Heterogeneous: Non-uniform composition (e.g., Chalk in water, Oil in water). 2. Atomic Structure
: Avoid long sentences. Use bullet points for properties and definitions to aid quick memorization. Flashcards : Create cards for specific "must-know" facts like Avogadro’s number ) or the three isotopes of Hydrogen ( Protium, Deuterium, Tritium One-Page Mind Maps chemistry notes ssc
Chemistry is a high-scoring section of the General Awareness module in SSC exams like CGL, CHSL, MTS, and CPO. Unlike dynamic subjects, the chemistry syllabus remains constant, focusing primarily on conceptual clarity and everyday applications.
Crystalline form, hexagonal layered structure, soft and slippery, good conductor of electricity due to free electrons. Used as a lubricant and in pencils. Fullerene ( C60cap C sub 60 Formed by cooling a gas of extremely low
Proposed by , it states: "The physical and chemical properties of elements are periodic functions of their atomic numbers." Structure of Modern Periodic Table It contains 7 Horizontal Rows called Periods . It contains 18 Vertical Columns called Groups . Group 1: Alkali Metals (Lithium, Sodium, Potassium, etc.)
Arranged elements in groups of three where the middle element's mass was the average of the other two. Atomic Structure : Avoid long sentences
Arranged elements by atomic mass; noticed every eighth element shared similar properties (like musical notes).
Indefinite shape. Definite volume. Low compressibility.
This section yields highly repetitive questions regarding pH values, indicators, and everyday chemical properties. Key Concepts Sour taste. Turn blue litmus red. Release H+cap H raised to the positive power ions in water. pH range: 0 to 6.9.
Here are the most effective strategies to master chemistry for your SSC preparation.
