Potassium has three naturally occurring isotopes: potassium-39, potassium-40, and potassium-41. The most common isotope is potassium-39, which makes up about 93% of naturally occurring potassium.
Assuming it's scandium(III), which is its most common valence state, the formula would be Sc2Se3.

Potassium 31 is potassium's normal state, the way you would find it on the Periodic Table. I presume potassium 41 is an isotope of potassium. (An isotope is the same atom, but it has a different number of neutrons, so the mass differs.)
The most likely oxidation state of an element is determined by the number of valence electrons it has. Elements tend to react in a way that allows them to achieve a full outer electron shell, often following the octet rule. This leads to the most common oxidation state for that element.
The valence of hydrogen which is a common element of living matter is 1. The other elements are oxygen which has a valence of 2, nitrogen has a valence of 3 and carbon has a valence of 4.
