What is an Alkaline Metal? - Where are they on the Periodic Table
- An Alkaline Metal is any of the elements on the left-hand side of the Periodic Table. It includes Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr). These elements are very reactive.
What Reaction did we do yesterday?
- Observation: When it was placed into the water the metal was fizzing and did give off fire sparks. Within the next 5 Seconds, it exploded and looked like a small firework. After the explosion, it gave off a strong smoke and smell.
- Reactants: Sodium + Water
- Products: Sodium Oxide + Hydrogen Gas
- Chemical Equation: Sodium + Water -> Sodium Oxide + Hydrogen Gas
(NA + H2O -> Na2O + H2)
Why do these metals react this way?
- They only have one electron in their outer shell that reacts very easily.
