Question

like iron and gold mentioned in the movie, aluminum is an element. what can you conclude about a piece of pure aluminum?
a it is made of a single, individual atom

b it is made of only protons

c it is made of many aluminum atoms

d it is made of iron, gold, and aluminum atoms

Explanation:

• Option A: An element like aluminum in a piece of pure aluminum is made of many atoms, not a single atom. So A is wrong.
• Option B: Atoms (including aluminum atoms) are made of protons, neutrons, and electrons, not just protons. So B is wrong.
• Option C: An element is a pure substance made of only one type of atom. Pure aluminum, being an element, is made of many aluminum atoms. This is correct.
• Option D: Pure aluminum should only contain aluminum atoms, not iron or gold atoms. So D is wrong.

Answer:

C. It is made of many aluminum atoms
