Here’s the of the properties of alkaline earth metals:
1. Physical Properties
- Shiny, silver-colored metals
- Harder than alkali metals
- Higher melting and boiling points than alkali metals
- Conduct heat and electricity
2. Chemical Properties
- Less reactive than alkali metals
- React with oxygen to form oxides
- React with acids to form salts and hydrogen gas
- Reactivity increases down the group
3. Reaction with Water
- Be: does not react with cold water
- Mg: reacts slowly with hot water
- Ca, Sr, Ba: react with cold water → form hydroxide + H₂
4. Other Notes
- Form ionic compounds
- Used in cement, fireworks, and medicine
Short summary:
Shiny, hard metals that react slowly; reactivity increases down the group.
