Question

1. fluorine, chlorine, bromine, and iodine all have the same number of valence electrons and have a tendency to gain electrons. which element has the greatest tendency to gain electrons? bromine iodine fluorine chlorine

Explanation:

Electronegativity is the measure of an atom's tendency to gain electrons. Among fluorine, chlorine, bromine, and iodine (halogens), fluorine has the highest electronegativity due to its small atomic size and high nuclear - charge - to - electron - shell ratio, which allows it to attract electrons more strongly.

Answer:

C. fluorine
