What's the difference between K(potassium) and K+.

K+ means that it is a positive ion, which means it must be missing a negative charge. This negative charge is provided with an electron.

K+ has one less electron than K, as denoted by the single positive charge.

K is the element; Potassuim metal. K+ is the ionised form (found in water)

Well is there a K-?

It would be rare in a normal situation, but there's no reason that it could not be created
