Group 1A Elements (Alkali Metals):
1. They are highly reactive metals.
2. They have low melting and boiling points.
3. They are soft and can be easily cut with a knife.
4. They have low densities.
5. They have a single electron in their outermost shell.
6. They readily lose their outermost electron to form a +1 cation.
7. They react vigorously with water to form alkaline hydroxides and hydrogen gas.
8. They are good conductors of heat and electricity.
9. They form ionic compounds with non-metals.
10. They are stored under oil to prevent reaction with moisture in the air.
Group 2A Elements (Alkaline Earth Metals):
1. They are less reactive than alkali metals.
2. They have higher melting and boiling points compared to alkali metals.
3. They are harder and denser than alkali metals.
4. They have two electrons in their outermost shell.
5. They readily lose their two outermost electrons to form +2 cations.
6. They react with water, but not as vigorously as alkali metals.
7. They are good conductors of heat and electricity.
8. They form ionic compounds with non-metals.
9. They are commonly found in minerals such as limestone and gypsum.
10. They are used in various industrial applications, such as in the production of steel and aluminum.
