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 charge of a potassium ion?
Potassium is a group 1 element, so it will form a 1+ ion.
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.
In the compound potassium bromide determine the charge on the potassium ion and the charge on the bromide ion?
The charge on the potassium ion is +1, as it is a Group 1 element. The charge on the bromide ion is -1, as it gains one electron to achieve a full octet in its outer shell.
Which element forms an ion with the same charge as the ammonium ion?
The element hydrogen forms an ion with the same charge as the ammonium ion, which is +1. When hydrogen loses an electron, it becomes a hydrogen ion with a +1 charge, just like the ammonium ion.
What is e major atom in potassium?
The major atom in potassium is the potassium ion, which has a positive charge of +1 and a single electron in its outermost shell. This ion is stable and commonly found in compounds like potassium chloride (KCl) and potassium hydroxide (KOH).
