Boron is a metalloid with the symbol B, and sulfate is a polyatomic ion with the formula SO₄²⁻. To form a neutral compound, we need to balance the charges.

* Boron has a +3 charge (B³⁺).

* Sulfate has a -2 charge (SO₄²⁻).

To balance the charges, we need two boron ions (2 x +3 = +6) and three sulfate ions (3 x -2 = -6).

Therefore, the chemical formula for boron and sulfate is B₂(SO₄)₃.
