K+
You can predict the ions of many elements using the periodic table. Metals in Groups 1A and 2A, as well as Al (in Group 3A) lose all their valence electrons when becoming ions. That is, they lose electrons until they have the same number as the previous noble gas. Since K has one valence electron (one more than Ar), it loses that one electron to become K+. (The ion has a positive charge because there are 19 positive protons in the nucleus and only 18 negative electrons.)

What is the chemical ion formula for potassium?
The Chemical Formula for Potassium Ion is K+.
How many electrons does a potassium ion have?
Potassium ion has 18 electrons.
What happens when a potassium ion and a flouride ion combine?
Potassium fluoride of KF is formed.
When a potassium atom forms an ion it loses one electron what is the electrical charge of the potassium ion?
K+
What is a charge of potassium?
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).
What is the charge of a potassium ion?
Potassium is a group 1 element, so it will form a 1+ ion.
Which element forms an ion with the same charge as the ammonium ion?
potassium
Is potassium a polyatomic ion?
No, infact Potassium is the chemical element with the symbol K.
Is potassium neutral or ion?
Potassiuim metal is neutral. Potassium in a solution of water forms an ion. Potassium in a compound with almost any other element forms an ionic bond.
Which element has chemical properties that are most similar to the chemical properties of sodium?
Potassium. Sodium is in group1 (period2) the next heaviest element is potassium (period 3). Potassium forms salts with the K+ ion.
How many electrons does a potassium atom give up when it becomes an ion?
Potassium is a Group I element (group 1) and therefore LOSES 1 electron to achieve full outer shells and become an ion.
What is the chemical formula for sulfate ion and a Potassium ion?
The potassium ion is K+ and the sulfate ion is SO42-
What is the chemical ion formula for potassium?
The Chemical Formula for Potassium Ion is K+.
What happens when potassium achieves a noble gas state?
Potassium loses one electron to form K+ ion that has the noble gas configuration of the element neon.
How many electrons does a potassium ion have?
Potassium ion has 18 electrons.
Which one has the larger radius potassium ion or bromide ion?
Potassium.
Does a banana have potassium atoms or potassium ions?
It has potassium ions... an ion is what fills the highest occupied energy level... if it were just potassium atoms, u would blow up when you eat bananas... once the potassium bonds with another element it becomes stable
