The charge of potassium as metal, elementary, (pure) is zero, neutral, it is an element (K).
Though in compounds it changes to an ION ( K+ ) with charge +1, because it donated its ONE outer electron to an oxidising agent (eg. oxygen).
The charge on a potassium ion of the type stable in salts is +1. Other charges are possible in near-vacuum under the influence of an electrical field, but these ions are not stable at normal temperature and pressure.
Potassium is a group 1 element, so it will form a 1+ ion.
Potassium metal has zero charge and a +1 charge (ionized state).

Potassium permanganate, KMnO4, has charge = 0
K+
Positive
KCl, K is potassium which has a +1 charge and Cl is Chloride which has a -1 unless by itself because it is a diatomic but in this formula it remains a -1 charge.
KPO4 does not exist. PO4 has a 3- charge, and K has a 1+ charge. So, you need to have K3PO4 to have potassium phosphate.
Usually if potassium has a charge, it is +1.
Potassium permanganate, KMnO4, has charge = 0
1+
Charges: Potassium = +1 Ferricyanide = -3
Potassium Dichromate K2Cr2O7 is neutral.
K+
potassium is an alkali metal with a charge of +1. It will bond with anything with a negative charge. With the elements, they want to form perfect bonds. That is, a neutral charge of 0. So the greater the negative charge, the more potassium atoms that can be bonded to it.
Potassium has a charge of +1. It is positively charged.
the chemical formula for potassium and Oxygen is: K2O Because Potassium has a charge of 1+. And Oxygen has a charge of 2- Hope this helps!
KC2H3O2 potassium has a +1 charge Acetate ion has a -1 charge
Potassium is a Group (I) metal. All Group(I) metals ionise to M^+ So potassium becomes K^+. Its ionic charge is '+1'.
+ 1
