Properties of Period 3 elements and their oxides (A-level only)

Describe the observations when sodium reacts with cold water.

A
  • Sinks as a solid block
  • Remains stationary
  • Glows brightly as oxygen is produced
B
  • Melts into a ball
  • Dashes across the surface
  • Fizzes rapidly as hydrogen is produced
C
  • Melts into a thin film
  • Moves slowly beneath the surface
  • Reacts silently as oxygen is produced
D
  • Forms a white precipitate
  • Dashes across the bottom
  • Fizzes rapidly as chlorine is produced
