A metallic bond . Are malleable (can be hammered and made into different shapes) and ductile (can be drawn into wires) This is because the layers of positive metal ions, in the metal structure, are able to slide . Crystalline microstructures are arranged in three-dimensional arrays called lattices.Swipe to navigate through the chapters of this book Close hint.
If the metals remain soluble when solid, the alloy forms a solid solution, becoming a homogeneous structure consisting of identical crystals, called a phase.
