Looking at the line plots on your graph, describe how boiling point and melting point vary with respect to atomic number. The boiling and melting points increase consistently as atomic number increases.

The boiling and melting points increase consistently as atomic number increases.

The boiling and melting points go up and down as the atomic number increases and there is no clear trend.
