Question

Quizplus · Accepted Answer

Elements in a column of the periodic table, also known as a group or family, have the same electron configuration. This is because they have the same number of valence electrons, which determine the element's chemical properties. While elements in a column may have similar chemical properties, they do not necessarily have the same size, nuclear properties, or nuclear charge.
