Which element in each of the following pairs has more metallic character? (a) Bi or As

Metallic character refers to the tendency of an element to exhibit properties typical of metals, such as conductivity, malleability, ductility, and luster. It increases down a group in the periodic table and decreases across a period from left to right. Understanding this concept is crucial for comparing elements, as it helps predict their behavior and reactivity.

Periodic trends are patterns observed in the properties of elements as you move across or down the periodic table. Key trends include atomic radius, ionization energy, electronegativity, and metallic character. Recognizing these trends allows for informed predictions about the properties of elements, such as which element in a pair is more metallic.

The position of an element in the periodic table significantly influences its properties, including metallic character. Elements located towards the left and bottom of the table tend to be more metallic, while those on the right and top are more non-metallic. In the case of bismuth (Bi) and arsenic (As), their positions help determine which has greater metallic character.
