Question

Collect information regarding metallic character of elements of IA group and prepare report tosupport the idea of metallic character increases in a group as we move from top to bottom.

Answer 1

metallic character increase due to increase in size

Answer 2

Metallic characters increases down the group.

The ability to loose electrons by valence shell easily by forming ions is the basic character of Metals.

• As we move down the group atomic radius decrease
• As we go down the group shielding of valence electrons by penultimate electrons increases .
• As we move down the group Ionization enthalpy decreases loosing electrons from valence shell easily.
