Question

21. Which one of the following is true about metallic character when we move from left
to right in a period and top to bottom in a group?

Decreases in a period and increases along the group
b)
Increases in a period and decreases in a group
c)
Increases both in the period and the group
d)
Decreases both in the period and in the group​

Answer 1

Answer:

Metallic character decreases as you move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. 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.
