Question

elements, compounds, & mixtures retake
classify each of the pictures below as
a = element
b = compound
c = mixture of elements
d = mixture of compounds
e = mixture of elements and compounds
each circle represents an atom and each different color represents a different kind of atom. if two atoms are touching then they are bonded together.

Explanation:

Step1: Recall definitions

An element consists of only one - kind of atom. A compound has two or more different kinds of atoms bonded together. A mixture is a combination of different substances.

Step2: Analyze picture 1

All the circles are the same color, so it is an element. Answer: A

Step3: Analyze picture 2

There are groups of atoms bonded together with different - colored atoms in each group, so it is a compound. Answer: B

Step4: Analyze picture 3

There are both single atoms of different colors (elements) and groups of bonded atoms (compounds), so it is a mixture of elements and compounds. Answer: E

Step5: Analyze picture 4

There are different - sized and - colored circles not bonded together, so it is a mixture of elements. Answer: C

Step6: Analyze picture 5

All the circles are the same color, so it is an element. Answer: A

Step7: Analyze picture 6

There are different - colored circles not bonded together, so it is a mixture of elements. Answer: C

Step8: Analyze picture 7

There are both single atoms of different colors (elements) and groups of bonded atoms (compounds), so it is a mixture of elements and compounds. Answer: E

Step9: Analyze picture 8

There are groups of atoms bonded together with different - colored atoms in each group, so it is a compound. Answer: B

Step10: Analyze picture 9

All the circles are the same color, so it is an element. Answer: A
