Understand the concept of metallic character: Metallic character refers to how easily an atom can lose electrons and form positive ions. Elements with high metallic character are typically metals, while those with low metallic character are non-metals.
Identify the position of elements in the periodic table: Metallic character increases as you move down a group and decreases as you move across a period from left to right.
Compare the elements given in the options: Rb (Rubidium) is located in Group 1 and is a metal with high metallic character. O (Oxygen) is located in Group 16 and is a non-metal with low metallic character.
Evaluate the difference in metallic character: The greatest difference in metallic character will be between elements that are far apart in terms of their metallic and non-metallic nature.
Determine the pair with the greatest difference: Among the given options, Rb and O are the most extreme in terms of metallic and non-metallic character, making them the pair with the greatest difference.
