Within each column, or group, of the table, all the elements have the same number of valence electrons.
Within each column, or group, of the table, all the elements have the same number of valence electrons. This explains why all the elements in the same group have very similar chemical properties.
exact same columns defined by the number of valence electrons.
Explanation:
Electrons in the outermost shell are called valence electrons, because it is their interactions that determine the chemical properties of an element. The columns that were set up to group elements by similar chemical properties turn out to be the exact same columns defined by the number of valence electrons
