Why are elements with Hugh electron affinities also the most electronegative?

Answer 1

you can think of it like a magnet.

A magnet with a peice of metal stuck to it.

The harder it is to pull a peice of metal away from it (ionization energy), that means that it has more pull on the metal and will pull peices of metal with more force(electron affinity).

Answer 2

Because some elements have much greater effective nuclear charge compared to others.

For example, Fluorine is the most electronegative element known, this is due to fact that it's electrons experience a great amount of attraction from it's positive nucleus.

This effect diminishes as you go left across the Periodic Table and down a group because in both cases, effective nuclear charge (attraction to the nucleus felt by the electrons) decreases.

Answer 3

The elements that have 5 or more or sometimes 4 electrons tend to need to gain electrons to form an octet, resulting in high electronegativity because they take electrons away from other elements.

Answer 4

A high ionisation energy means it is very difficult to take away electrons, which is a basic definition of high electron affinity.
