Question

how does the metallic character change along the period?

Answer 1

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

The metallic character change along the period from left to right because as the atoms move readily accept electrons to fill a valence shell and than lose them to remove the unfilled shell.
