Mastering chemistry for the SSC (Staff Selection Commission) exams requires a strategic approach. Chemistry falls under the General Awareness section, which can significantly boost your overall score if you prepare efficiently.

Discovered by James Chadwick. Neutral charge. Mass is slightly greater than a proton. Key Atomic Terms

Atoms bond with one another to achieve a stable electronic configuration, similar to the nearest noble gas (octet rule).

Metals that melt when kept on the human palm due to very low melting points. chemistry notes ssc

Comprehensive notes cover Physical, Organic, and Inorganic Chemistry .

Decreases down a group, increases across a period.

In MCQs, you can quickly distinguish these by remembering that mixtures (like salt in water) can be separated by physical processes, while breaking down a compound (like water into hydrogen and oxygen) requires a chemical reaction.

Formed by the complete transfer of electrons from a metal to a non-metal (e.g., NaClcap N a cap C l MgOcap M g cap O Industrial manufacture of Nitric Acid ( HNO3cap H

Answer: Sodium Chloride ( Which gas is known as Laughing Gas? Answer: Nitrous Oxide (

To help you ace the General Science section, here is a comprehensive breakdown of the essential chemistry topics you need to master. 1. Matter and Its States

Definite shape, definite volume, high density, and strong intermolecular forces.

Discovered by James Chadwick . It is charge-neutral. Mass is Important Atomic Terms Neutral charge

Now, he uncapped the green pen and wrote the answer not in scientific jargon, but in a story: "Because when water freezes, it throws a party. The molecules get shy (hydrogen bonds) and stand an arm's length apart, becoming less dense. The solid, therefore, is a social butterfly that floats on the liquid wallflower."

Discovered by Ernest Rutherford (though Goldstein observed canal rays earlier). Neutron: Discovered by James Chadwick .

), which react with water molecules in the atmosphere to form sulfuric and nitric acids.

: This is a favorite for SSC. Learn the chemical names of common items: Baking Soda : Sodium bicarbonate Table Salt : Sodium chloride Nail Polish Remover : Acetone/solvent details Metals and Non-Metals : Study alloys, ores (like for Uranium), and properties like malleability.
