The Modern Periodic Table organizes elements based on their increasing atomic number. This law was framed by Henry Moseley. Structure of the Periodic Table : 7 horizontal rows. Groups : 18 vertical columns. Group 1 : Alkali Metals (e.g., Lithium, Sodium, Potassium). Group 2 : Alkaline Earth Metals (e.g., Magnesium, Calcium). Groups 3–12 : Transition Elements.
: Focus on chemical properties and common ores (e.g., Hematite for Iron ). Know which metals are stored in kerosene (Sodium) or which are liquid at room temperature (Mercury). chemistry notes ssc

exam was only two days away. Spread across the rickety wooden table were his Chemistry Notes for SSC
Physical combinations of two or more substances in any ratio. No chemical reaction occurs.
Mastering Chemistry is essential for scoring high on Staff Selection Commission (SSC) exams like CGL, CHSL, MTS, and CPO. General Science questions in the General Awareness section often feature foundational chemistry concepts.
