Question

Help?

Answer 1

Are there any options you feel that you can rule out first?

Answer 2

C?

Answer 3

That's correct, it can't be C because you can see that the objects have different shapes in the image. What else?

Answer 4

Thats all i know

Answer 5

Cool, you can also rule out A because it is possible for objects of the same element to have different amounts of that substance. Likewise, it cannot be D because the number of atoms depends entirely on the number of moles of material present, which is not provided. This leaves answer choice B, which is correct because elements are how different kinds of atoms are classified.
