for questions that ask us to compare two elements and decide which one is more ionic, will we be given a periodic table with the electronegativity values?

On the periodic table that we got for test 1, we didn't get electronegativity values. However, if we're just comparing values, we have to know the trends of electronegativity across the periodic table.

The trend is that electronegativity increases from left to right, and increases from bottom to top of the periodic table.

Usually if electronegativity values are needed they would be provided because the periodic table doesn't show the numeric values of electronegativity, it is important to know how the trend works which is from bottom to top and left to right.

In the midterm, I believe that we only will have a basic periodic table. We should know the trends for electronegativity, electron affinity, ionization energy and such and be able to identify it.
