# 6.3.1: Practice Naming

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.

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.

copper (I) sulfide   [The copper must be Cu1+ in order for two of them to balance the one S2–]

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.

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.

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.

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 N3–

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 HSO31–

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 C2H3O21–
