← ScienceWhich consequence results when localized corrosion severs metallic bonds?
A)Decrease in electrical conductivity✓
B)Increase in oxide layer thickness
C)Formation of passivating film
D)Increase in tensile yield strength
💡 Explanation
Severing bonds due to corrosion reduces the number of free electrons available for charge transport, therefore electrical conductivity decreases, because electron mobility depends on intact metallic lattices, rather than oxide presence relating to passivity.
