* Potassium (K) is an alkali metal, meaning it has one valence electron that it readily loses to achieve a stable octet configuration. This results in a +1 charge.

* Sulfate (SO₄²⁻) is a polyatomic ion with a -2 charge.

* To form a neutral compound, two potassium ions (K⁺) are needed to balance the -2 charge of the sulfate ion.

Therefore, the formula for potassium sulfate is K₂SO₄, and potassium has an electrovalency of +1 in this compound.
