There are 19 protons in a potassium atom, ion, and isotope. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons.

How many electrons in potassium?
Potassium is a metal element. There are 19 electrons in a single atom.
How many protons are in an ion?
The number of protons present in an ion is equivalent to its atomic number.
What is the number of protons in Fe 3 plus?
There are similar number of protons in the ion and the atom. Fe+3 ion contains 26 protons.
If a nitride ion has a charge of -3 the ion must have how many protons?
The number of protons is 7.
How many protons are in pottasium?
Pottasium is a meta element. Atomic number of it is 19.
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 protons are in a Potassium ion?
19
How many protons does patassium have?
A potassium atom has 19 protons.An uncharged atom therefore has 19 electrons, but in solution many potassium atoms exist as ions (K+), with 18 electrons.
How many electrons potassium ion?
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 many protons and electrons does K have?
19 electrons, 19 protons and 20 neutrons
How many protons are in an ion?
The number of protons present in an ion is equivalent to its atomic number.
How many electrons in potassium?
Potassium is a metal element. There are 19 electrons in a single atom.
What type of ion does potassium form?
Potassium has to lose 1 electron in order to form an ion. Once it does, it is known as a cation (ion with a positive charge,) and its symbol is K+
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.
Which element has19 protons in its nucleus?
Potassium - (K) Potassium's atomic number is 19, which is also the number of protons it has.
What is the number of protons in Fe 3 plus?
There are similar number of protons in the ion and the atom. Fe+3 ion contains 26 protons.
What element has 19 protons 21 neutrons and 18 electrons?
ONLY the K+ ion (not element) has 19 protons and 18 electrons.The isotopic ion with 21 neutrons must be K+-40 , the most rare potassium-ion (0.01%) out of three possibles, the other isotopes are: K+-39 (93%) and 7% is K+-41Explanation:39, 40 and 41 are the mass numbers of the 3 naturally occurring potassium isotopes.Keep in mind that:1. an element is always neutrally charged, so the number of protons (positives, + ) equals the number of electrons (negatives, - )2. the number of neutrons depends on the 'mass number' of the one particular isotope of that element and that the number of protons + neutrons is the mass number
