Question

PLEASE HELP ME!!

Write formulas for the following compounds:

a. lithium fluoride, lithium chloride, lithium bromide, lithium iodide, lithium oxide, lithium sulfide

b. sodium fluoride, sodium chloride, sodium bromide, sodium iodide, sodium oxide, sodium sulfide

c. potassium fluoride, potassium chloride, potassium bromide, potassium iodide, potassium oxide, potassium sulfide

d. ammonium fluoride, ammonium chloride, ammonium bromide, ammonium iodide, ammonium sulfide

Answer 1

The chemical formulas provided represent common ionic compounds formed by alkali metals, ammonium ions, and various anions. Formulas such as LiF for lithium fluoride, LiCl for lithium chloride, and NaBr for sodium bromide illustrate the neutrality of charge in these compounds.

Step-by-step explanation:

Writing Formulas for Ionic Compounds

3. Lithium bromide: LiBr
4. Lithium iodide: LiI
5. Lithium oxide: Li2O
6. Lithium sulfide: Li2S
7. Sodium fluoride: NaF
8. Sodium chloride: NaCl
9. Sodium bromide: NaBr
10. Sodium iodide: NaI
11. Sodium oxide: Na2O
12. Sodium sulfide: Na2S
13. Potassium fluoride: KF
14. Potassium chloride: KCl
15. Potassium bromide: KBr
16. Potassium iodide: KI
17. Potassium oxide: K2O
18. Potassium sulfide: K2S
19. Ammonium fluoride: NH4F
20. Ammonium chloride: NH4Cl
