Question

ductility and malleability
two very important properties of metals are ductility and malleability. ductility is the ability to be drawn into wires. malleability is the ability to be hammered or pressed into shapes. both ductility and malleability can be explained by the mobility of delocalized valence electrons in a metal.
metals vs. ionic compounds a sea of valence electrons allows metals to be squeezed into wire or hammered without breaking. ionic compounds do not behave the same way.
when pressure is applied to a metal, the cations easily change position, so the metal changes shape without breaking. this is an example of malleability.
in contrast, applying pressure to an ionic compound tends to push the ions close together. the positive ions repel each other, and the crystal shatters.
24 sep plan an investigation you want to compare the malleability of two metals. plan an investigation that would allow you to determine which metal is more malleable.

Explanation:

To compare the malleability of two metals, we can use a hammer to apply equal - force impacts on samples of each metal of the same size and shape. Measure the extent of deformation (e.g., thickness after hammering, area of spread) without the metal breaking. The metal that deforms more under the same force is more malleable.

Answer:

1. Take two metal samples of the same size and shape.
2. Use a calibrated hammer to apply a series of equal - force impacts on each sample.
3. Measure and record the thickness and spread area of each sample after each impact.
4. The metal that shows greater deformation (less thickness and larger spread area) without breaking is more malleable.
