### 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

A. Metals
Explanation
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.

### Which class of element is sulfer (S)?

• A.

Metal

• B.

Non-metal

• C.

Metalloid

B. Non-metal
Explanation
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.
