Metallic character decreases from left to right in the periods and increases down the group

Answer 1

Answer:

Explanation: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

Answer 2

Answer:

Down the group, the effective nuclear charge experienced by valence electrons decreases because the outermost electrons move further away from the nucleus. ... Hence, metallic character decreases across a period and increases down a group.
