Which of the following elements is likely to exhibit the most metallic character?Group of answer choicesPotassiumCarbonSiliconPhosphorus

The most metallic character is likely to be exhibited by Potassium.

Here's why:

1. Metallic character refers to the level of reactivity that a metal has. Metals tend to lose electrons in chemical reactions, as opposed to nonmetals, which gain electrons.

2. The elements listed are all found in different groups of the periodic table. Potassium is in Group 1 (the alkali metals), Carbon and Silicon are in Group 14, and Phosphorus is in Group 15.

3. As you move from right to left across a period in the periodic table, metallic character increases. This is because the elements on the left side of the periodic table tend to lose electrons (a characteristic of metals) more readily than those on the right side.

4. Therefore, out of Potassium, Carbon, Silicon, and Phosphorus, Potassium (being the furthest to the left) is likely to exhibit the most metallic character.
