Potassium, or K, has an atomic number of 19. Therefore, its electrically neutral form would have 19 protons and 19 electrons. An ion of potassium, labeled K+, has had one of its electrons removed; therefore it only has 18 electrons.

How is a potassium atom (K) different from a potassium ion (K )?
Potassium consists of potassium atoms with their valence electrons delocalized throughout the metal, put those electrons still essentially "belong" to their atoms. A potassium ion is a potassium atom that has lost its valence electron to another atom molecule or ion and therefore carries a 1+ charge.
Potassium k has an atomic number of 19 it often forms an ion by losing 1 electron how many electrons would the ion have?
18
Potassium (K) has an atomic number of 19. It often forms an ion by losing 1 electron. How many electrons would the ion have?
18
Which is larger NA ion or k ion and why?
A potassium ions is larger than a sodium ion, because potassium ions contain more electrons and consequently occupy more space.
What is the charge of a potassium ion that has 18 electrons and 19 protons?
Since the atomic number of potassium is 19, a potassium ion with 18 electrons has one net positive charge; the formula is K+1.
How many electrons does a potassium ion have?
Potassium ion has 18 electrons.
How many valence electron are in a potassium ion?
Potassium has 19 electrons when it's neutral. It's ionic form is K+. Thus, the potassium ion has one less electron than that, or 18.

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.
Which is larger NA ion or k ion and why?
A potassium ions is larger than a sodium ion, because potassium ions contain more electrons and consequently occupy more space.

Does pottassium (k) gain or lose electrons?
Potassium is more likely to lose its electron to become a positive ion.
