Alkali Metal

Alkali metals are highly reactive in nature and it is impossible to find these metals in its original form in nature. Alkali metal has a low melting point and low density as well. These metals are,

Lithium Sodium Potassium Rubidium Cesium Francium

These metals would easily react with halogen elements to form alkali metal salts and when it reacts with water it will form a very strong base.

Q: Why are they so easy to react?

A: Because in their outer shell, they only have one electron, and this causes alkali metals become very unstable (stable if 2 or 8). So in nature to stabilize their bond, they would bind other elements.

Summarize the properties of alkali metals:

1. highly reactive

2. React with halogens to form salts

3. Reacts with water to form a strong base

4. An outer electron

5. soft

6. Low melting point

7. This type of low-mass

8. Potential for very low ionization

9. Rate electronegativity: Li> Na> K> Rb> Cs> Fr

10. Level of reactivity: Li <Na <K <Rb <Cs <Fr

11. Melting point and steam point: Li> Na> K> Rb> Cs> Fr
