Absolutely! Let’s solve Part 1 of this worksheet step by step.
---
- Metal: Elements typically found on the left side and center of the periodic table (e.g., Na, Mg, Ca, Fe, Cu, Rb, Al).
- Non-metal: Elements typically found on the right side of the periodic table (e.g., O, N, H, F, Cl, I, C, S, P).
- Ionic Bond: Formed between a metal + non-metal.
- Covalent Bond: Formed between non-metal + non-metal.
> ⚠️ Note: Some elements like Aluminum (Al) are metals, even though they can sometimes behave like non-metals in certain compounds — but for basic classification, Al is a metal.
> Also, diatomic molecules like O₂ are pure non-metals bonded covalently to themselves.

- Element 1: Ca = metal
- Element 2: O = non-metal
- Bond Type: Ionic
---
- Element 1: H = non-metal

---
- Element 1: O = non-metal
- Element 2: O = non-metal
- Bond Type: Covalent
> 💡 This is a diatomic molecule — two identical non-metals sharing electrons.

## 🧠 Summary Tips:
- If both elements are non-metals → Covalent
- If one is metal and one is non-metal → Ionic
- Hydrogen is always treated as a non-metal in this context.
- Transition metals (like Fe, Cu) are still metals → form ionic bonds with non-metals.
