Verified step by step guidance1
Understand that the periodic table is arranged in groups (columns) and periods (rows), where elements in the same group share certain characteristics.
Recall that the atomic number is unique to each element and increases as you move across periods, so elements in the same group do not have the same atomic number.
Recognize that elements in the same group have the same number of valence electrons, which are the electrons in the outermost shell responsible for chemical behavior.
Know that having the same number of valence electrons leads to similar chemical properties among elements in the same group.
Conclude that the most common shared property of elements in the same group is their similar chemical properties due to having the same number of valence electrons.
