An atom is the smallest particle of an element that retains its properties. It consists of three subatomic particles:

Halogens (Fluorine, Chlorine, Bromine, Iodine) — highly electronegative. Fluorine is the most electronegative element. Bromine is the only non-metal that is liquid at room temperature.

Focus on pH value and natural sources.

Latent Heat: Heat required to change the state without changing temperature. 2. Atomic Structure Understanding the building blocks of matter is crucial. Proton (discovered by Ernest Rutherford/Goldstein). Electron (J.J. Thomson). Neutron (James Chadwick). Atomic Terms: Atomic Number (Z): Number of protons. Mass Number (A): Protons + Neutrons.

Arranged elements by atomic mass; noticed every eighth element shared similar properties (like musical notes). chemistry notes ssc
