In the periodic table, elements are arranged based on their atomic structure, which influences their chemical behavior and properties. One important aspect of this arrangement is the concept of atomic radius, which is the distance from the nucleus to the outermost shell of electrons. As we move from left to right across a period, the atomic radius changes due to the increase in nuclear charge with additional protons.
Consider the following elements in the same period: Lithium (Li), Beryllium (Be), and Boron (B). Which of these elements has the largest atomic radius?
