Question

has the maximum metallic character.

Answer 1

• As we move down the group metallic characters increase while going across a period from left to right, metallic characters decrease.
• The alkali metals in group 1 are the most active metals except hydrogen.
• The metallic order of alkali metals: $\mathrm{Li}<\mathrm{Na}<\mathrm{K}<\mathrm{Rb}<\mathrm{Cs}<\mathrm{Fr}$
• Francium is a radioactive element and is found very rare. So, cesium is the most metallic element.

Hence, Cesium has the maximum metallic character.
