Question

Metallic Character

The ability of an atom to donate electrons and form positive ion (cation) is known

as electropositivity or metallic character. Down the group, metallic character

increases due to increase in atomic size and across the period, from left to right

electropositivity decreases due to decrease in atomic size.

Non-Metallic Character

The ability of an atom to accept electrons to form a negative ion (anion) is

called non-metallic character or electronegativity. The elements having high

electro-negativity have a higher tendency to gain electrons and form anion.

Down the group, electronegativity decreases due to increase in atomic size

and across the period, from left to right electronegativity increases due to

decrease in atomic size

(i) Which of the following correctly represents the decreasing order of

metallic character of Alkali metals plotted in the graph?

a) Cs>Rb>Li>Na>K

b) K>Rb>Li>Na>Cs

c) Cs>Rb>K>Na>Li

d) Cs>K>Rb>Na>Ki​
