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).
Potassium permanganate, KMnO4, has charge = 0
The common charge for the element potassium is +1.
K+
The formula for potassium oxide would be K2O. This is because potassium has a valence of 1 and oxygen has a valence of 2. To balance the charges, you need two potassium ions (each with a charge of +1) for every oxygen ion (with a charge of -2).
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.
Usually if potassium has a charge, it is +1.
Charges: Potassium = +1 Ferricyanide = -3
Potassium permanganate, KMnO4, has charge = 0
The common charge for the element potassium is +1.
In potassium sulfate (K2SO4), the sulfur atom carries a charge of -2 because each potassium atom contributes a +1 charge, resulting in a total charge of +2 for the potassium ions. The overall compound is electrically neutral.
Potassium Dichromate K2Cr2O7 is neutral.
Two potassium ions are needed to balance the charge of one sulfide ion. Potassium has a +1 charge and sulfide has a -2 charge, so two potassium ions with a +1 charge each are required to balance the -2 charge of the sulfide ion.
Potassium is a Group (I) metal. All Group(I) metals ionise to M^+ So potassium becomes K^+. Its ionic charge is '+1'.
You would need two potassium ions to balance the charge of one sulfide ion. Potassium has a charge of +1, while sulfide has a charge of -2, so two potassium ions with a total charge of +2 would balance the charge of one sulfide ion with a charge of -2.
1+
Potassium nitride is composed of potassium (K) and nitrogen (N) atoms. It has the chemical formula K3N. It is an ionic compound where potassium has a +1 charge and nitrogen has a -3 charge.
An atom of potassium-41 becomes a potassium ion with a plus charge by losing one electron. Potassium-41 has 19 electrons in its neutral state, but when it loses one electron, it becomes a potassium ion (K+) with a plus charge and 18 electrons.
