Hi everyone here we have a question asking which statement is true. A chromium is less ductile than copper because it has stronger metal metal bonding. Be Chromium is less ductile than copper because it has weaker metal metal bonding. See, chromium is more ductile than copper because it has random metal metal bonding or d chromium is more ductile than copper because it has no metal metal bonding activity. Is the property related to the ease with which a solid can be drawn into a wire basically the softer the solid, the more ductile it is, the more rigid the solid, the less ductile it is for metals do activity decreases as the strength of metal metal bonding increases, producing a stiffer, less susceptible to distortion. Chromium has six valence electrons with a field bonding band and strong metal metal interactions and rigid lattice copper has 11 valence electrons with a nearly filled anti bonding band and filled bonding band. Therefore chromium has strong metal metal bonding has stronger metal metal bonding than copper, so chromium is less ductile. So our answer here is a chromium is less ductile than copper because it has stronger metal metal bonding and that is our final answer. Thank you for watching. Bye.
