Properties of Metals worksheet for educational use.

Let’s work through this step by step.

Step 1: Understand the task

The worksheet is about “Properties of Metals” and has three main parts:

1. Shade the periodic table to show where metals are located.
2. Classify 12 elements as metal, non-metal, or metalloid.
3. Mark statements as true (T) or false (F) about metals.

Since we can’t actually shade a table in text, we’ll focus on parts 2 and 3 — which are written answers.

Part 2: Classify the elements

We need to know whether each element is a metal, non-metal, or metalloid.

Here’s a quick reference:

- Metals: Most elements on the left and center of the periodic table (e.g., sodium, calcium, iron).
- Non-metals: Right side (e.g., oxygen, nitrogen, sulfur, chlorine).
- Metalloids: Along the “staircase” line between metals and non-metals — usually include boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po).

Now let’s go one by one:

(a) Antimony (Sb) → Metalloid
(b) Sulfur (S) → Non-metal
(c) Sodium (Na) → Metal
(d) Silicon (Si) → Metalloid
(e) Iodine (I) → Non-metal
(f) Manganese (Mn) → Metal
(g) Germanium (Ge) → Metalloid
(h) Oxygen (O) → Non-metal
(i) Barium (Ba) → Metal
(j) Boron (B) → Metalloid
(k) Platinum (Pt) → Metal
(l) Uranium (U) → Metal

✔ Double-checking:
- Sb, Si, Ge, B are classic metalloids.
- S, I, O are non-metals.
- Na, Mn, Ba, Pt, U are all metals.

Part 3: True/False statements about metals

Let’s evaluate each statement:

(a) *Mostly occupy the left and middle section of the periodic table.* → True
→ Yes, metals are mostly on the left and center.

(b) *Most or the majority of elements.* → True
→ About 80% of elements are metals.

(c) *They are usually solids at room temperature.* → True
→ Except mercury (Hg), which is liquid.

(d) *Often solid, they are usually brittle.* → False
→ Metals are usually malleable and ductile, not brittle. Brittle is more for non-metals like sulfur.

(e) *Can react with other elements to form ionic compounds.* → True
→ Metals lose electrons to form positive ions → ionic bonds with non-metals.

(f) *Usually poor conductors of electricity.* → False
→ Metals are good conductors!

(g) *Good producers of heat.* → True
→ They conduct heat well.

(h) *Are sometimes found in elemental form in nature.* → True
→ Like gold, silver, copper — sometimes found pure.

(i) *Have a characteristic shiny appearance.* → True
→ That’s called luster — a key property of metals.
