The atom with the highest first electron affinity is Fluorine (F).

Here's why:

1. Electron affinity is the amount of energy released when an electron is added to a neutral atom to form a negative ion.

2. Fluorine (F) has the highest electron affinity because it has seven valence electrons and only needs one more to achieve a stable, full outer energy level.

3. When an electron is added to a Fluorine atom, a large amount of energy is released because the added electron is greatly attracted to the positively charged nucleus. This makes Fluorine the most electron-loving (or "electron-affine") element.

4. Other atoms like Barium (Ba), Beryllium (Be), and Bromine (Br) do not have as high electron affinities as Fluorine because their atomic structures do not allow for as stable of an energy state when an extra electron is added.
