This effect explains the hardness of alloys like brass (CuZn, which has the BCC structure), which are made by combining two soft metals (Cu and Zn, which are respectively FCC and HCP as pure metals, are both soft and ductile).
Malleability and Ductility: The electron-sea model of metals not only explains their electrical properties but their malleability and ductility as well. The sea of electrons surrounding the protons acts like a cushion, and so when the metal is hammered on, for instance, the overall composition of the structure of the metal is not harmed or changed.
Malleability and Ductility: The sea of electrons surrounding the protons act like a cushion, and so when the metal is hammered on, for instance, the over all composition of the structure of the metal is not harmed or changed.
Most metals are malleable – they can be bent and shaped without breaking. This is because they consist of layers of ions that can slide over one another when the metal is bent, hammered or...
Malleability and ductility: A metal can be hammered into sheets and drawn into wires. These shapes are possible because the atoms share electrons and slide past each other. High melting and boiling points: The metallic bond is formed due to the strong electrostatic forces between the sea of electrons and cations.
A model showing how metallic bonds are formed - the first diagram shows the outer electrons in their atoms, and the second diagram shows that the electrons have become delocalised. Learn more...
Malleability If something is malleable, it just means that it can be easily moulded, bent, hammered or rolled into a different shape. Metals are malleable since the atoms are arranged in a regular pattern that can easily slide over each other!
