Exercise \(\PageIndex{1}\)

Name the compound below. Hint: Is it ionic or covalent? Is the cation predictable or variable?

MgSO₄

Hint: It is ionic. It is predictable, so no Roman numerals are needed. Just name cation and name anion.
Answer: magnesium sulfate

Exercise \(\PageIndex{1}\)

Name the compound below. Hint: Is it ionic or covalent? Is the cation predictable or variable?

Cu₂S

Hint: It is ionic. It is variable, so you must determine the charge needed to make a total of zero charge. Roman numeral is needed.
Answer: copper (I) sulfide [The copper must be Cu¹⁺ in order for two of them to balance the one S^2–]

Exercise \(\PageIndex{1}\)

Name the compound below. Hint: Is it ionic or covalent? Is the cation predictable or variable?

Fe(NO₃)₃

Hint: It is ionic. It is variable, so you must determine the charge needed to make a total of zero charge. Roman numeral is needed.
Answer: iron (III) nitrate

Exercise \(\PageIndex{1}\)

Name the compound below. Hint: Is it ionic or covalent? Is the cation predictable or variable?

Al(ClO₃)₃

Hint: It is ionic. It is predictable, so no Roman numerals are needed. Just name cation and name anion.
Answer: aluminum chlorate

Exercise \(\PageIndex{1}\)

Name the compound below. (We are not dealing with peroxides. The anion is regular oxide.) Hint: Is it ionic or covalent? Is the cation predictable or variable?

PtO₂

Hint: It is ionic. It is variable, so you must determine the charge needed to make a total of zero charge. Roman numeral is needed.
Answer: platinum (IV) oxide

Exercise \(\PageIndex{1}\)

Write the formula of the compound below. Hint: draw each ion first. Then put them together so they make a compound with zero charge.

calcium nitride

Hint: Ca²⁺ and N^3–
Answer: Ca₃N₂

Exercise \(\PageIndex{1}\)

Write the formula of the compound below. Hint: draw each ion first. Then put them together so they make a compound with zero charge.

lithium bisulfite

Hint: Li¹⁺ and HSO₃^1–
Answer: LiHSO₃

Exercise \(\PageIndex{1}\)

Write the formula of the compound below. Hint: draw each ion first. Then put them together so they make a compound with zero charge.

nickel (III) acetate

Hint: Ni³⁺ and C₂H₃O₂^1–
Answer: Ni(C₂H₃O₂)₃
