What is the difference between a potassium atom and a potassium 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.
Why is K+ important?
Physiologic Role. Potassium ion (K+) is perhaps the most frequently supplemented electrolyte. Potassium plays an important role in cell membrane physiology, especially in maintaining resting membrane potential and in generating action potentials in the nervous system and heart.
