Question

a research student used a new software package to calibrate the electronic map using a material containing only gallium and bromine bonds, ga and br. on which atoms might you expect to see the highest electron density?
ga because is is more electropositive
br because is is more electropositive
ga because is is more electronegative
br because is is more electronegative

Explanation:

Electronegativity is the ability of an atom to attract electrons in a chemical bond. Bromine (Br) has a higher electronegativity than gallium (Ga). In a bond between Ga and Br, electrons will be more attracted to the more electronegative atom. So, the highest electron density will be on the more electronegative atom.

Answer:

Br because is is more electronegative
