# What are five properties of metals?

Apr 2, 2017

$\left(i\right)$ $\text{Malleability}$, the ability to be hammered out into a sheet....

#### Explanation:

$\left(i i\right)$ $\text{Ductility}$, the ability to be drawn out into a wire....

$\left(i i i\right)$ $\text{Thermal conductivity}$, the ability to conduct heat....

$\left(i v\right)$ $\text{Electrical conductivity}$, the ability to conduct electricity....

$\left(v\right)$ $\text{Chemical reactivity}$, metals tend to be good reducing agents.......

All of these properties may be rationalized on the basis of our view of metallic bonding, which is typically described as $\text{positive ions in an electron sea}$. The metal atoms contribute 1 or more valence electrons to the bulk metal lattice such that there are delocalized electrons in the lattice.
