Question

19. The Metallic property of elements Increases down the group in modern periodic
table why?
​

Answer 1

Answer:

Metallic character increases as you move down an element group in the periodic table. This is because electrons become easier to lose as the atomic radius increases, where there is less attraction between the nucleus and the valence electrons because of the increased distance between them.

Answer 2

Answer:

Metallic character increases on going down to the group because of the lesser nucleus force, the electrons become easier to lose as atomic radius increases. Metals are on the left-hand side of the periodic table except hydrogen.

 Metallic properties increase down groups as decreasing attraction between the nuclei and the outermost electrons cause the outermost electrons to be loosely bound and thus able to conduct heat and electricity.

radium

Among the group 2 elements, radium is known to have the greatest metallic character and it can, therefore, be considered the most metallic group 2 element. This is because the metallic character of elements increases while traversing down a group, and radium is at the bottom of group 2 in the modern periodic table
