Sodium Metal 100gm
Chemical Formula: Na
Appearance: Sodium metal is a soft, silvery-white, highly reactive metal. It is shiny when freshly cut but tarnishes rapidly in air due to oxidation.
Physical Properties:
- Atomic Number: 11
- Density: 0.97 g/cm³ at 20°C
- Melting Point: 97.79°C (207.02°F)
- Boiling Point: 883°C (1621°F)
- Hardness: Sodium is soft enough to be cut with a knife.
- Reactivity: Sodium is highly reactive, especially with water, producing sodium hydroxide and hydrogen gas. This reaction is exothermic and can be explosive. 2Na+2H2O→2NaOH+H22Na + 2H_2O → 2NaOH + H_22Na+2H2O→2NaOH+H2
- Oxidation: In air, sodium rapidly oxidizes, forming a layer of sodium oxide (Na_2O).
