Worksheet 1 – Element Hunt Overview
| Question | Correct Answer | Why it’s right |
|---|---|---|
| 1 | O₂ | Oxygen’s atomic number is 8; the question asks for the diatomic molecule. |
| 2 | NaCl | Sodium (Na) + Chlorine (Cl) → NaCl, the classic table salt. Plus, |
| 3 | H₂O | Hydrogen (1) + Oxygen (8) → 2 + 1 = 3; the simplest water molecule. |
| 4 | CO₂ | Carbon (6) + 2×Oxygen (8) → 6 + 16 = 22; carbon dioxide. Because of that, |
| 5 | CaCO₃ | Calcium (20) + Carbon (6) + 3×Oxygen (8) → 20 + 6 + 24 = 50; limestone. |
| 6 | Fe₂O₃ | Iron (26) ×2 + Oxygen (8) ×3 → 52 + 24 = 76; rust. On the flip side, |
| 7 | Al₂(SO₄)₃ | Aluminum (13) ×2 + Sulfate (SO₄) ×3 → 26 + (32 + 64) × 3 = 26 + 288 = 314. |
| 8 | KNO₃ | Potassium (19) + Nitrate (NO₃) → 19 + (14 + 48) = 81. Plus, |
| 9 | CuSO₄ | Copper (29) + Sulfate (SO₄) → 29 + (32 + 64) = 125. |
| 10 | AgNO₃ | Silver (47) + Nitrate (NO₃) → 47 + (14 + 48) = 109. |
Detailed Walkthrough
1. Atomic Numbers and Diatomic Molecules
The first question asked for the diatomic form of the element with atomic number 8. Oxygen is 8, so the answer is O₂. Remember, many elements exist as diatomic gases—H₂, O₂, N₂, Cl₂, Br₂, I₂. When a question mentions “diatomic,” it’s a hint to add the subscript 2.
2. Ionic Compounds
The second question was straightforward: combine sodium (Na) and chlorine (Cl). Sodium is +1, chlorine is –1, so they form the neutral compound NaCl. The trick is to keep the charges balanced.
3. Simple Water Molecule
Hydrogen has an atomic number of 1, oxygen is 8. The question asked for the simplest water molecule, so you just pair one hydrogen with one oxygen. The subscript 2 comes from the fact that two hydrogen atoms bond to one oxygen.
4. Carbon Dioxide
This one is a classic. Carbon is 6, oxygen is 8. Two oxygens plus one carbon give you CO₂. The subscript 2 on oxygen shows there are two oxygen atoms in the molecule.
5. Calcium Carbonate
Here you’re adding three elements: calcium (20), carbon (6), and oxygen (8). The formula CaCO₃ tells you calcium (1) + carbon (1) + three oxygens (3). The subscript 3 on oxygen is a clue that there are three oxygen atoms.
6. Iron Oxide (Rust)
The formula Fe₂O₃ indicates two iron atoms and three oxygen atoms. Iron’s atomic number is 26, oxygen’s is 8. Multiply and add: 26 × 2 + 8 × 3 = 52 + 24 = 76 Small thing, real impact..
7. Aluminum Sulfate
Al₂(SO₄)₃ combines two aluminum atoms with three sulfate ions. Each sulfate ion contains one sulfur (32) and four oxygens (4 × 8 = 32). So each sulfate is 32 + 32 = 64. Multiply by three for the whole molecule, then add the aluminum That's the part that actually makes a difference..
8. Potassium Nitrate
KNO₃ is potassium (19) + nitrate (NO₃). The nitrate ion has one nitrogen (14) and three oxygens (3 × 8 = 24). Sum them: 19 + (14 + 24) = 81 And that's really what it comes down to. Simple as that..
9. Copper Sulfate
CuSO₄ is copper (29) + sulfate (SO₄). Using the same sulfate calculation as before (32 + 64 = 96) and adding copper gives 29 + 96 = 125 And that's really what it comes down to..
10. Silver Nitrate
AgNO₃ is silver (47) + nitrate (NO₃). The nitrate ion is 14 + 24 = 38. Add silver: 47 + 38 = 85. Wait—hold on. The worksheet says 109. Why? Because the question actually asks for the molar mass of silver nitrate, not the sum of atomic numbers. Silver nitrate’s molar mass is 107.868 g/mol, rounded to 108. So the worksheet’s answer of 109 is a trick—rounding up Nothing fancy..
Common Mistakes / What Most People Get Wrong
- Ignoring subscripts – Students often forget that the subscript indicates how many atoms of that element are in the molecule.
- Mixing up atomic numbers with atomic masses – The worksheet sometimes asks for the molar mass, which is a different number.
- Skipping charge balance – For ionic compounds, not checking the net charge can lead to an unbalanced formula.
- Forgetting the diatomic hint – When “diatomic” is mentioned, the subscript 2 is almost always required.
- Misreading the question – Some questions ask for the formula, others for the molar mass. Double‑check what’s being asked.
Practical Tips / What Actually Works
- Write it out – Even if you’re confident, jotting down the formula helps you see where you might have skipped a subscript.
- Use a periodic table handy – Keep one open on your phone or print one out. A quick glance saves a lot of guesswork.
- Check the charge – For ionic compounds, add up the charges. If they don’t cancel to zero, you’ve got a typo.
- Round carefully – When the worksheet asks for a number, read the instructions: “Round to the nearest whole number” vs. “Give the exact value.”
- Cross‑reference – If you’re stuck, see if a previous question uses the same element. Patterns often repeat.
