The Formula for Terbium Sulfate Compound

The formula for a Terbium phosphate compound is Tb₃(PO₄)₄. What would be the formula for a Terbium sulfate compound, given that the charge of Terbium is the same in both compounds?

A) Tb₂(SO₃)₃
B) Tb(SO₄)₂
C) Tb(SO₃)₂
D) Tb₃(SO₄)₄
E) Tb(SO₄)₃

Final answer:

The formula for a Terbium sulfate compound, given that the charge of Terbium is the same in both compounds, would be Tb(SO₄)₂.

Explanation:

The formula for a Terbium sulfate compound, given that the charge of Terbium is the same in both compounds, would be Tb(SO₄)₂ (option B).

In the compound formula, the subscripts indicate the number of each ion needed to balance the charges.

Since the charge of Terbium is the same, we only need one Terbium ion.

The charge of the sulfate ion is -2, so we need two sulfate ions to balance the +3 charge of Terbium. Therefore, the formula for Terbium sulfate is Tb(SO₄)₂.

The formula for a Terbium sulfate compound, given that the charge of Terbium is the same in both compounds?
Which option represents the correct formula for Terbium sulfate compound? The correct formula for Terbium sulfate compound would be Tb(SO₄)₂ (option B).
