Quizplus · Accepted Answer

The ammonium ion has a charge of +1. This means that it has one more proton than it does electrons. Potassium, which is in the same group as ammonium on the periodic table (Group 1), also has a charge of +1 when it forms an ion. Therefore, potassium forms an ion with the same charge as the ammonium ion. None of the other choices have the same charge as the ammonium ion.
