Potassium (K ; Kalium) has Atomic No,. 19 in the Periodic Table.
The '19' tells us that potassium has 19 protons , and 19 electrons.
Potassium's Atomic Mass is '40' . This tells us the total number of nucleons in the nucleus of the atom.
Nucleons is the collective noun for protons and neutrons.
Since by the Atomic No. we know that there are 19 protons , then the number of neutrons is 40 - 19 = 21 neutrons.
Since protons and neutrons are given an arbitrary value of '1' each, then '40' is the atomic mass of patassium.
NB Some of your correspodents have stated that there is only 1 electron. This is completely wrong ; they have misunderstood. It has 19 electrons.
Potassium , like sodium ; Same Group '1' elements), readily ionise ONE electron
So the to form the ion K^(+). The other 18 electrons remains in the ion.
Since there are 19 protons ( 19 (+) positives, there musr be 19 electrons (19(-) negatives) to maintain an uncharged atom .
When one electron is ionised (lost) the atom becomes an ion and contains 19 (+) & 18(-) = 1(+) ; indicated as '+'
So the atomic symbol is 'K' , but the ionic symbol is 'K^(+)'.
K^(+) is a charged species , a cation. NOT an atom .
NNB Potassium can exhibit ISOTOPES . This is where the number of NEUTRONS can vary.
So the isotopes
K-39 has 20 neutrons, 19 protons, 19 electrons
K-40 has 21 neutrons , 19 protons, and 19 electrons
K-41 has 22 neutrons , 19 protons and 19 electrons.
However, as an example , an isotope of K-41 may ionise to K-41^(+)
This ion would contain 22 neutrons, 19 protons, an 18 elecgtrons.
Notice in ALL cases the number of protons does NOT change. A change in the number of protons means that it is a different element.
Hope that helps!!!!
I know that there are
Electrons: 1
Protons: 19
But I am still reaserching the nuetrons
I got this info off Answers.com ironicly so if I am wrong than I have no clue!
The atomic number of potassium (K) is 19. So there are 19 protons and 19 neutrons. In addition, in K-40 isotope, there are 21 neutrons (40 - 19 = 21)

How many protons electrons and neutrons does an atom of potassium have?
An atom of potassium has 19 protons, 19 electrons, and typically 20 neutrons.
How many protons neutrons and electrons in potassium -43?
Potassium-43 has 19 protons, 24 neutrons, and 19 electrons. The number of protons and electrons is determined by the element's atomic number (which is 19 for potassium), while the number of neutrons is calculated by subtracting the atomic number from the isotope mass number.
How many protons neutrons and electrons are in k39?
In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).
How many protons and nutrons does potassium have?
Potassium have th atomic number of 19 this means it has 19 protons in its "core" and in atoms the number of electrons are always equal to the number of protons hence also 19. the number of neutrons however vary dependent on witch potassium isotope it is the average for potassium is however 20 in potassium 39

19 protons.20 neutrons.18 electrons.One less electron that has been donation to form the potassium ion.K +----------------charge on the cation
How many protons electrons and neutrons in the element potassium?
The atomic number of potassium is 19. So there are 19 protons and 19 electrons. The number of neutrons depends on the isotope. The most stable isotope of potassium (K-39) has 20 neutrons (39 - 19 = 20).
How many protons neutrons and electrons are in k39?
In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).
How many protons electrons and neutrons does 31potassium have?
Potassium-31 has 19 protons, 19 electrons, and 12 neutrons. This can be determined by looking at the atomic number of potassium (which is 19) to find the number of protons and electrons, and subtracting the atomic number from the mass number to find the number of neutrons.
