Compare and contrast a potassium atom and a potassium ion. Explain how to change a potassium ion into a potassium atom and vice versa. In your explanation, show the symbols that would be used to represent the atom and the ion.

A potassium atom, K is in its normal elemental state with 1 valence electron in it's most outer shell. ... However the potassium ion has lost it's valence electron and has therefore formed a positive action, K+ . It instead has 19 protons and 18 electrons, yielding a net positive charge.
