Chemistry Notes Ssc -

Formed by the mutual sharing of electrons between non-metal atoms (e.g., H2Ocap H sub 2 cap O CO2cap C cap O sub 2 CH4cap C cap H sub 4

For aspirants preparing for the Staff Selection Commission (SSC) exams—such as CGL, CHSL, MTS, CPO, or GD—the Science section can often be a game-changer. Among the three core subjects (Physics, Chemistry, Biology), is often perceived as the most scoring, yet memorization-heavy, discipline.

Elements exhibiting properties of both metals and non-metals (e.g., Silicon ( ), Germanium ( ), Arsenic ( ), Antimony ( )). Used extensively as semiconductors. Important Alloys and Compositions

: 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

: Study chemicals used in everyday items like fertilizers, polymers, detergents, and food preservatives.

: Unsaturated hydrocarbons with at least one double bond. General formula: CnH2ncap C sub n cap H sub 2 n end-sub

Shiny (lustrous), malleable (can be beaten into thin sheets), and ductile (can be drawn into wires). Excellent conductors of heat and electricity. is the best conductor, followed by Copper ( Mercury ( ) is the only metal that is liquid at room temperature. Gallium ( ) and Cesium ( ) have very low melting points and melt on your palm. ) and Potassium ( ) are soft metals that can be cut easily with a knife. Non-Metals Formed by the mutual sharing of electrons between
