Step-by-step solution for: SOLUTION: Recall of metals non metals and metalloids worksheet ...
You're working on a periodic table classification activity — sorting elements into Metals, Metalloids, and Nonmetals based on their properties and positions on the periodic table.
Let’s break this down step by step and correct/complete the task.
---
## ✔ OVERVIEW OF THE THREE CATEGORIES:
- Properties: Ductile, Malleable, Lustrous, Low Ionization Energy
- Location: Left side and center of the periodic table (Groups 1–12, plus some in 13–16)
- Examples given: N T U B Z G A → these are likely typos or placeholders. Correct common metals include: Na, Ti, U, Be, Zn, Ga, Al, etc.
- Correct placement: The yellow cutout should cover everything to the left of the metalloid staircase, including transition metals, lanthanides, actinides, and alkali/alkaline earth metals.
✔ Your yellow cutout is mostly correct — it covers the left and center blocks. Just make sure it includes:
- All of Groups 1–2
- Transition metals (Groups 3–12)
- Lanthanides & Actinides (bottom rows)
- Some post-transition metals like Al, Sn, Pb, Bi
---
- Properties: Semi-conductors, used in computers
- Elements: B, Si, Ge, As, Sb, Te, Po, At (sometimes only B, Si, Ge, As, Sb, Te are considered classic metalloids)
- Location: Along the “staircase” line from Boron (B) to Polonium (Po)
✔ You listed B and Si — that’s correct, but you’re missing others.
🟢 Your green cutout should be a diagonal “staircase” starting at Boron (B), going down through Si, Ge, As, Sb, Te, and sometimes Po and At.
👉 In your image, the green cutout is correctly placed along the staircase — just make sure it includes all 6–8 metalloids, not just B and Si.
---
- Properties: Dull, Brittle (as solids), High Ionization Energy
- Location: Upper right corner of the periodic table (right of the staircase)
- Elements listed: O, N, C, F, S, H, P, Xe — these are all nonmetals! ✔️
- Also includes: Cl, Br, I, He, Ne, Ar, Kr, Rn, Se
🔵 Your blue cutout is placed in the top-right — that’s correct. But make sure it covers:
- All elements to the right of the metalloid staircase, including noble gases and halogens.
- Also include Hydrogen (H) — even though it’s on the far left, it’s a nonmetal!
⚠️ Important correction: Hydrogen (H) is a nonmetal, but it’s located in Group 1. So if your blue cutout doesn’t include H, you need to add it — even though it’s on the left side.

## 🧩 FINAL CHECKLIST FOR YOUR CUTOUTS:
| Category | Should Include | Your Cutout Status |
|--------------|----------------------------------------------------------------------------------|--------------------|
| Metals | Groups 1–2, transition metals, lanthanides, actinides, Al, Sn, Pb, Bi, etc. | ✔ Mostly correct |
| Metalloids | B, Si, Ge, As, Sb, Te, (Po, At) — staircase line | ⚠️ Add Ge, As, Sb, Te |
| Nonmetals | H, C, N, O, F, P, S, Cl, Se, Br, I, noble gases (He, Ne, Ar, Kr, Xe, Rn) | ⚠️ Add H, Cl, Br, I, noble gases |

## 💡 TIPS FOR PASTING THE CUTOUTS:
- Metals (yellow): Cover everything left of the staircase, including the bottom two rows.
- Metalloids (green): Trace the stair-step line from B to Po — this is the classic dividing line.
- Nonmetals (blue): Fill in everything to the right of the staircase, including Hydrogen (top-left corner).

## ✍️ WRITTEN ANSWER TO SUBMIT:
> Metals are located on the left side and center of the periodic table. They are ductile, malleable, lustrous, and have low ionization energy. Examples include sodium (Na), iron (Fe), and aluminum (Al).
>
> Metalloids lie along the staircase line between metals and nonmetals. They have properties of both and are often semiconductors. Key elements are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), and tellurium (Te).
>
> Nonmetals are found in the upper right corner (and hydrogen). They are dull, brittle as solids, and have high ionization energy. Examples include oxygen (O), nitrogen (N), carbon (C), fluorine (F), sulfur (S), phosphorus (P), and xenon (Xe). Hydrogen (H), though on the left, is also a nonmetal.

## ✔ CORRECTED CUTOUT PLACEMENT SUMMARY:
- Yellow (Metals): Everything left of the staircase + bottom rows.
- Green (Metalloids): Staircase line — B, Si, Ge, As, Sb, Te.
- Blue (Nonmetals): Right of staircase + Hydrogen.
