Answer:

A diamond is a pure substance because it is made of one element.

Explanation:

From the crystalline structure model of the diamond, we can see that we only have just one element represented by the green balls connected in a cross linked fashion to one another. Therefore, one can rightly conclude that this is a pure substance made up of one element.

In a pure substance, all parts are homogeneous and composition is definite.

What is a valence electron ?
timofeeve [1]

a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

How is iron extracted? Describe in brief​
Feliz [49]

Answer:Iron is extracted from iron ore in a huge container called a blast furnace. Iron ores such as haematite contain iron(III) oxide, Fe 2O 3. The oxygen must be removed from the iron(III) oxide in order to leave the iron behind. Reactions in which oxygen is removed are called reduction reactions.
