Metallic Bond - Definition and Properties [with Examples]
In the case of metals, the sea of electrons in the metallic bond enables the deformation of the lattice. Therefore, when metals are beaten with a hammer, the rigid lattice is deformed and not fractured. This is why metals can be beaten into thin sheets. Since these
Heavy metals - Wikipedia
Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic nuers.The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic nuer, while a chemist would likely be
