Barium because this is have a greatest tendency.
There is no Group 14. The elements of the group 7A are the most electronegative. Basically, electronegativity is the ability to attract electrons. Group 7A elements, or halogens, need just one more electron to reach stability, and are very reactive. So, they can easily accept that electron. In other words, their ability to attract electrons is the highest.
The ability to attract electrons is called electronegativity. An atom or a functional group can have this ability, and some have stronger electronegativity than others.
Chlorine has the highest electron affinity or the greatest tendency to attract a shared pair of electrons in a covalent bond.

Non-metals, especially group 17 and group 16 elements.
Nonmetals tend to attract electrons to become negative ions.
Electronegativity
The ability of an atom to attract electrons. The most electronegative elements are in the upper right hand corner of the Periodic Table, most notably fluorine.
Electron affinity is an elements' ability to attract electrons and is variable for each element. Generally the more electronegative atoms are furthest to the right bottom of the periodic table and ascending to the left the elements lose their electron accepting ability.
The periods near the top, i presume because they have less shielding from other electrons in their orbitals, therefore there will be a larger nuclear pull so easier to attract electrons. Obviously a element with a full shell or 1 or 2 electrons in it isn't really going to gain electrons and Transition metals are weird. Hope this helps :)
