Exercise \(\PageIndex{1}\)

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

CuCN

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) cyanide

Exercise \(\PageIndex{1}\)

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

N₂O₃

Hint: It is covalent. There is no cation. Use prefixes to tell how many of each element are in the formula.
Answer: dinitrogen trioxide

Exercise \(\PageIndex{1}\)

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

Sn₃(PO₄)₂

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: tin (II) phosphate

Exercise \(\PageIndex{1}\)

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

SO₃

Hint: It is covalent. There is no cation. Use prefixes to tell how many of each element are in the formula.
Answer: sulfur trioxide

Exercise \(\PageIndex{1}\)

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

Ba(OH)₂

Hint: It is ionic. It is predictable, so no Roman numeral is needed. Just name cation and name anion.
Answer: barium hydroxide

Exercise \(\PageIndex{1}\)

Write the formula of the compound below. Hint: is it ionic or covalent?

cadmium bromide

Hint: It is ionic. Draw ions then put them together to make zero charge.
Answer: CdBr₂

Exercise \(\PageIndex{1}\)

Write the formula of the compound below. Hint: is it ionic or covalent?

nitrogen dioxide

Hint: It is covalent. Use prefixes to figure out formula.
Answer: NO₂

Exercise \(\PageIndex{1}\)

Write the formula of the compound below. Hint: is it ionic or covalent?

sulfur hexafluoride

Hint: It is covalent. Use prefixes to figure out formula.
Answer: SF₆
