On the test do we have to know to know the electronegativity of elements?
Is there way to calculate the electronegativity of an element?

Electronegativity is a calculated value, but for the test, we will not need to calculate or memorize the values.

The values that represent the electronegativity of elements are arbitrary and only used for comparison between elements.

We won't need to know exact numbers, just trends. Electronegativity increases up and to the right of the periodic table.

You do not need to know the values for electronegativity. However, you should know the trends for electronegativity which follows the same trends as ionization energy and electron affinity. This is reasonable because electronegativity is calculated based on the values of ionization energy and electron affinity. If the ionization energy and electron affinity of an atom is high, then the atom will have a high electronegativity which will cause it to pull shared electrons towards it.

If Lavelle does give us a question asking us to compare the electronegativity between two elements he will have to provide us a periodic table with the corresponding electronegativity values or the values in general

As many of the others say, you just need to know the basic trends for electronegativity and it would probably be helpful to understand the boundary of which two elements would form covalent and ionic bond.

A trick I use is to just memorize that fluorine is the most electronegative element, and note its position on the periodic table.
