(B) Metallic character is defined by the tendency of an element to lose electrons. Across a period,as the effective nuclear charge increases and atomic size decreases,the tendency to lose electrons decreases,so metallic character decreases. Down a group,the atomic size increases and the valence electrons are further from the nucleus,making them easier to lose,so metallic character increases.
