Which element has the most metallic character?

In the periodic table, metallic character generally increases as you move from right to left across a period and from top to bottom down a group (or column). Therefore, elements found in the lower left corner of the periodic table tend to exhibit the most metallic character.

Among the elements, francium (Fr) is often considered to have the most metallic character. Francium is located in Group 1 of the periodic table, which is also known as the alkali metals group. Elements in this group, such as sodium (Na) and potassium (K), are highly metallic in character, and francium is expected to exhibit similar characteristics due to its position in the same group. However, it's essential to note that francium is a highly radioactive element with a very short half-life, making it extremely rare and challenging to study in detail. As a result, its properties are not as well-documented as some other elements.
