____ are elements which can form positive ions by the loss of electrons.

Read the following and answer the question Metallic Character: The ability of an atom to donate electrons and form positive ion (cation) is known as electro-positivity or metallic character. Down the group, metallic character increases due to increase in atomic size and across the period, from left to right electro-positivity 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 electro-negativity increases due to decrease in atomic size. Which of the following correctly represents the decreasing order of metallic character of Alkali metals plotted in the graph ?
