Which element has the highest electronegativity and why?

See below

Explanation:

Hello there!

Electronegativity is the atom's tendency to attract electrons in a chemical bond

There are two trends to electronegativity:

Electronegativity increases from bottom to top in a group (Li has a greater electronegativity than Fr, for example) Electronegativity increases from left to right across a period (the further right the group, the greater the electronegativity)

Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.

Sn belongs to group 4A (group 14) Sb belongs to group 5A (group 15)Te belongs to group 6A (group 16) I belongs to group 7A  (group 17)

As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity

Hope this helps!
