Ques: Answer the following question given this paragraph: You can see how Mendeleev organized the elements in the Figure below . From left to right across each row, elements are arranged by increasing atomic mass.

He called the columns groups . They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family.
