Would an atom with high electronegativity more likely react with an atom with high ionization energy or low ionization energy?? Why???

Answer

It would be more likely to react with an atom with low ionization energy. Electronegativity refers to an atoms ability to attract electrons to it. If it has a high electronegativity, it has an easier time attracting electrons. This is important when it comes to forming bonds in which electrons are being shared (like in covalent bonds).

hope this answers your question! :)
