Atoms, Molecules, Elements, Compounds Quiz Questions
The atom is the smallest particle of an element. The atoms make up molecules, which in turn makeup elements. In the chemistry classes this week we discussed all the three and a test on this is moving closer. Use the quiz to polish up what you know so far. All the best!

Which class of elements is to the left of the zig-zag line on the periodic table of elements?
- A.
Metals
- B.
Non-metals
- C.
Metalloids
Correct Answer
A. MetalsExplanation
To help answer this question, find the zig-zag line on the periodic table of elements. Look for metals you are familiar with on the table. You should find iron, gold, silver and many others on the left side of the zig-zag line. This is your clue that this is the area that has the metals.
Non-metals are to the right of the zig-zag line.
Metalloids are found along the zig-zag line.Rate this question:

Which class of element is sulfer (S)?
- A.
Metal
- B.
Non-metal
- C.
Metalloid
Correct Answer
B. Non-metalExplanation
To help answer this question, find the zig-zag line on the periodic table of elements. Look for metals you are familiar with on the table. You should find iron, gold, silver and many others on the left side of the zig-zag line. This is your clue that this is the area that has the metals.
Non-metals are to the right of the zig-zag line. Since sulfer is in this area, it is a non-metal.
Metalloids are found along the zig-zag line.Rate this question:
