Metals and Alloys

  • Joon Bu Park


The metal atoms are held together by the interactions of the valence electrons (outermost electrons) and the positive metallic ions. The electrons are free to move throughout the solid (sea of electrons) because the valence electrons are not bound between metal ions. Such an arrangement is called the metallic bond, to distinguish it from the covalent bond, in which electrons are shared between one another (Fig. 4–1).
