Questions about elements, compounds, and mixtures?

I need 1 example of each (element, compound, and mixture), the definition of each, and an idea for a picture.

1) Element: gold: Definition-Gold is a chemical element with the symbol Au (from aurum, "shining dawn", hence adjective, aureate) and an atomic number of 79. It has been a highly sought-after precious metal for coinage, jewelry, and other arts since the beginning of recorded history

For a picture-Ring, necklace etc.
2) Compound: Sodium chloride
Definition-Sodium chloride, also known as salt, common salt, table salt or halite, is an inorganic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms.

3) Milk is a mixture of water with various proteins, fats, and other substances. So is oxygen a mixture.
A mixture is what you get when you combine two substances in such a way that no chemical reaction occurs between the components and you can separate them again.
