Introduction to Alkali Metals
Alkali metals are a group of elements in the periodic table known for their unique properties and reactivity. They include lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Position in the Modern Periodic Table
- Alkali metals are located in the first group (Group 1) of the Modern Periodic Table.
- This group is characterized by having one electron in their outermost shell, which they readily lose to form positive ions (cations).
Properties of Alkali Metals
- Highly Reactive: Alkali metals are highly reactive, especially with water, forming hydroxides and releasing hydrogen gas.
- Softness: They are soft and can be cut with a knife.
- Low Density: Most alkali metals have low densities, with lithium, sodium, and potassium being less dense than water.
Trends in Alkali Metals
- Increasing Reactivity: Reactivity increases down the group. For example, sodium reacts with water more vigorously than lithium.
- Melting and Boiling Points: These decrease down the group, with cesium having a much lower melting point than lithium.
Conclusion
The correct option for the group assigned to alkali metals in the Modern Periodic Table is 'D' (First group). Their distinctive properties and trends highlight their significant role in chemistry and various applications.
