📋 How to Read a Cell
- Top-left number — Atomic number (protons)
- Large symbol — Chemical symbol (1–2 letters)
- Full name — Element name
- Bottom number — Atomic mass (u)
🎨 Colour Categories
- Red — Alkali metals (group 1)
- Yellow — Alkaline earth metals (group 2)
- Blue — Transition metals (d-block)
- Purple — Halogens | Sky — Noble gases
📚 Periodic Trends (Class 10–12)
- Atomic radius — decreases → across period; increases ↓ down group
- Ionisation energy — increases → across period
- Electronegativity — increases → across period (F is highest)
- Metallic character — increases ↓ down group
