Worksheet for practicing naming and writing formulas of simple binary ionic compounds.

I'll help you complete this nomenclature worksheet for simple binary ionic compounds. Let me work through each compound systematically.

For compounds 1-10 (given names, need formulas):

To write formulas for ionic compounds, I need to balance the charges so the compound is neutral.

1. Sodium bromide: Sodium (Na) has +1 charge, Bromide (Br) has -1 charge → NaBr
2. Calcium chloride: Calcium (Ca) has +2 charge, Chloride (Cl) has -1 charge → CaCl₂
3. Magnesium sulfide: Magnesium (Mg) has +2 charge, Sulfide (S) has -2 charge → MgS
4. Aluminum oxide: Aluminum (Al) has +3 charge, Oxide (O) has -2 charge → Al₂O₃
5. Lithium phosphide: Lithium (Li) has +1 charge, Phosphide (P) has -3 charge → Li₃P
6. Cesium nitride: Cesium (Cs) has +1 charge, Nitride (N) has -3 charge → Cs₃N
7. Potassium iodide: Potassium (K) has +1 charge, Iodide (I) has -1 charge → KI
8. Barium fluoride: Barium (Ba) has +2 charge, Fluoride (F) has -1 charge → BaF₂
9. Rubidium nitride: Rubidium (Rb) has +1 charge, Nitride (N) has -3 charge → Rb₃N
10. Barium oxide: Barium (Ba) has +2 charge, Oxide (O) has -2 charge → BaO

For compounds 11-20 (given formulas, need names):

11. K₂O: K = potassium (+1), O = oxide (-2) → Potassium oxide
12. MgI₂: Mg = magnesium (+2), I = iodide (-1) → Magnesium iodide
13. AlCl₃: Al = aluminum (+3), Cl = chloride (-1) → Aluminum chloride
14. CaBr₂: Ca = calcium (+2), Br = bromide (-1) → Calcium bromide
15. Na₃N: Na = sodium (+1), N = nitride (-3) → Sodium nitride
16. LiF: Li = lithium (+1), F = fluoride (-1) → Lithium fluoride
17. BaP₂: Ba = barium (+2), P = phosphide (-3) → Barium phosphide
18. Cs₂S: Cs = cesium (+1), S = sulfide (-2) → Cesium sulfide
19. SrF₂: Sr = strontium (+2), F = fluoride (-1) → Strontium fluoride
20. NaCl: Na = sodium (+1), Cl = chloride (-1) → Sodium chloride

Let me double-check my work by verifying the charge balances:

1. NaBr: +1 + (-1) = 0 ✓
2. CaCl₂: +2 + 2(-1) = 0 ✓
3. MgS: +2 + (-2) = 0 ✓
4. Al₂O₃: 2(+3) + 3(-2) = +6 - 6 = 0 ✓
5. Li₃P: 3(+1) + (-3) = 0 ✓
6. Cs₃N: 3(+1) + (-3) = 0 ✓
7. KI: +1 + (-1) = 0 ✓
8. BaF₂: +2 + 2(-1) = 0 ✓
9. Rb₃N: 3(+1) + (-3) = 0 ✓
10. BaO: +2 + (-2) = 0 ✓

All formulas are correctly balanced!
