Which element has highest metallic character? - Quora

Cesium, the metallic character increase down the group and mostly metals arevpresent in the left side of the periodic table. Since francium is radioactive it is not their in the story. We can clarify this by considering the ionization energy, which is the key property of metals. As metallic character increases ionisation energy decreases.

Transition Metals — Properties of the Element Group

Because they possess the properties of metals, the transition elements are also known as the transition metals.These elements are very hard, with high melting points and boiling points. Moving from left to right across the periodic table, the five d orbitals become more filled. The d electrons are loosely bound, which contributes to the high electrical conductivity and malleability of the
