Write down 1 significant difference between copper and bronze and iron in terms of their availability and distribution?

Here are some differences

Explanation:

The differences and some facts-Copper:

This element is also malleable, soft, its also ductile metal with high thermal and electrical conductivity.

Its symbol is 'Cu'Its melting point is 1,984°F which is 1,085°CThe density is 8.96 g/cm near room temperatureCopper doesn't rust but it corrodes, which makes it turns from its natural brown to a bright green.Bronze:

This is an alloy, it is also much harder than copper, and its less ductile. Bronze also turns green due to chemical reactions between copper in the alloys and the atmosphere.

Bronze is copper colored There is no odorIts melting point is from 950 degrees C to to 1050 degrees CBronze has a relative density of ~8.8 g/cc.Bronze is a strong conductor of heat. Iron:

This is another chemical element . Iron is less dense than bronze, this can also be bent very easily, but bronze cannot be. Bronze is also stronger  than iron.

Its symbol is 'Fe'Its melting point is 2,800°F which is 1,538°CThe density is 7.874 g/cm near room temperatureIron is also the sixth most common element in the universe.

It is state and federali really hope this
