Collect information regarding metallic character of elements of IA gro

1.	Collect information regarding metallic character of elements of IA group and prepare report to support the idea of metallic character increases in a group as we move from top ro bottom.
Answer» Metallic character of IA group elements : 1. Alkali metals exhibit many of the physical properties common to metals but their densities are lower than those of other metals. 2. Alkali metals have one electron in their outer shell which is loosely bound. 3. They have largest atomic radii of the elements in their respective periods. 4. The lower ionization energies result in their metallic properties and high reactivities. 5. An alkali metal can easily lose its valence electron to form positive ion. 6. So they have greater metallic character. 7. The metallic character increases as we move from top to bottom in group due to addition of another shell, it is easy to lose electron.

Metallic character of IA group elements :

1. Alkali metals exhibit many of the physical properties common to metals but their densities are lower than those of other metals.

2. Alkali metals have one electron in their outer shell which is loosely bound.

3. They have largest atomic radii of the elements in their respective periods.

4. The lower ionization energies result in their metallic properties and high reactivities.

5. An alkali metal can easily lose its valence electron to form positive ion.

6. So they have greater metallic character.

7. The metallic character increases as we move from top to bottom in group due to addition of another shell, it is easy to lose electron.
