How do you determine which element is less electronegative in a compound element?

Electronegativity decreases down a group and increases across a period.

Look at its position on the periodic table. Electronegativity increases from left to right across a period and decreases down a group.

Elements that typically form negative ions are more electronegative. These are typically on the right side of the periodic table because these elements are trying to accept more electrons and complete their outer shells.

You can look at the periodic table and using the trend that it increases up and to the right (excluding noble gases), be able to compare between two elements.

I believe an atom's electronegativity is relative to their ionization energy (increases from left to right and down to up of the periodic table) , so I would just follow the trend for ionization energy to determind an atom's electronegativity.
