A higher atomic weight than the one on its left. For example, magnesium (atomic weight 24.3) is placed to the right of sodium (atomic weight 23.0): 2. Similar chemical properties to other elements in the same column-in other words similar chemical reactions.Magnesium, for example, is placed in the alkali earths' column: Mendeleev realized that the table in front of him lay at the very heart of chemistry.or example, magnesium (atomic weight 24.3) is placed to the right of sodium (atomic weight 23.0): 2.
