a.1.(Chem. & Physics) Having the property of being attracted by an electro-positive body, or a tendency to pass to the positive pole in electrolysis, by the law that opposite electricities attract each other. Contrasted with neutral and electropositive
2.Negative; nonmetallic; acidic; - opposed to positive, metallic, or basic.
3.(Physics) carrying a negative electrical charge.
4.(Chem. and Physics) having a tendency to take up electrons and form negative ions; having a relatively positive electrode potential.
n.1.(Chem. & Physics) A body which passes to the positive pole in electrolysis; an anion.

Non-metals, such as halides, are characterized by a valence shell with a few electrons short of a stable configuration, and as such, gain electrons resulting in an electro-negative ion.
Since the cathode is positive with respect to the anode on the pipe surface, the corrosion cell current can be reduced or eliminated by introducing a counter (cathodic protection) current into the electrolyte to cause the cathode to be as electro-negative as the anode.
They are metals that have a more electro-negative voltage value than that of the pipe corrosion cell.
This causes the pipe surface to be more electro-negative than the original corrosion cells on the pipeline.
