Final answer:Among the given options, K (Potassium) has the largestatomic radius. The atomic radius of an atom generally increases as we move down a group in the periodic table because of the addition of energy levels.Explanation:The size of an atom is determined by its atomic radius, which is impacted mainly by its number of energy levels. Each of the atom options,Li (Lithium), K (Potassium), Si (Silicon), B (Boron), falls in different periods of the periodic table. It's important to note that as we move down a group (vertically) on the periodic table, the atomic radius increases due to the addition of energy levels. Among the given optionsK (Potassium)is the furthest down the periodic table indicating it has the largest atomic radius. The increase in principal quantum number, n, means more energy levels are added, increasing the size of the atom. Except in cases where the atom loses or gains electrons to form ions, the atomic radius generally increases with the atomic number.Learn more about Atomic Radius here:brainly.com/question/13607061#SPJ11...
