Question

On moving down the group the metallic character of bottom element is …... than that of the top atom (less, more)

Answer 1

First of all we should know about the metallic character. The level of reactivity of a metal is defined by the metallic character. Generally the metals have the properties to lose electrons in chemical reactions. The metal atoms within a compound generally have relatively low attraction for electrons, as indicated by their low electronegativity.

Complete step-by-step answer: Metallic character is mainly defined as the ease with which a metal loses its electron. It depends on the effective nuclear charge and also from the distance of the electrons from the nucleus.
According to the modern periodic table, the metallic character of an element generally decreases while moving from left to right across a period. The metallic character of an element increases on moving down the group.
Most of the metallic elements generally show malleability, ductility, luster, thermal and electrical conductivity.
The most metallic natural element is Cesium. The most metallic element is Francium, however it is man-made and the least metallic elements are Helium, Neon, Fluorine, and Oxygen.

Thus, the metallic character of the bottom element is more than that of the top atom.

Note: The periodic table is divided into three groups such as metals, nonmetals and metalloids. In periodic tables most of the elements are generally metals. They are generally shiny, very dense and melt only at very high temperatures. Metals can generally be converted into thin sheets and wires without breaking.
