Halogens and their compounds | Group 7 Elements in Periodic Table
Introduction to Halogens and their compounds (The group 7th elements)
In this video, you'll get a clear, syllabus-focused breakdown of:
What are the halogens? (Definition & position in the periodic table)
The five halogens: Fluorine, Chlorine, Bromine, Iodine, Astatine
Physical properties: Color, state, and trends down the group
Chemical properties: High reactivity, electron configuration, oxidizing ability
Why they are called "halogens" (meaning "salt formers")
Trends in Group 7:
Melting & boiling points
Reactivity trend (decreases down the group)
Atomic size & electronegativity
