What is electron configuration of potassium ion?
(Ar) 4s¹Potassium / Electron configuration
How do you find the electron configuration of potassium?
We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the next six electrons. We now shift to the 4s orbital where we place the remaining electron. Therefore the Potassium electron configuration will be 1s22s22p63s23p64s1.
Is the number of proton and electron the same in a potassium ion?
It is always constant. (e.g., H=1, K=19, Ur=92). So if you look for potassium (symbol K in the periodic table), you will find that it has the atomic number of 19. This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons– also 19 electrons.
Which of the following elements is most similar to potassium?
Explain your answer. Sodium and potassium share similar physical and chemical properties because they are in the same family or group called Alkali metals. Both will have the same valence electrons and they are both very reactive.
What is the full electron configuration of potassium?

What is the electron configuration of an ion?
We can determine the electron configuration for an ion by first finding the electron configuration for the neutral atom and then adding or subtracting electrons depending on the charge of the ion.
How do you write the electron configuration for K+?

What is the electron configuration of K+ quizlet?
Since K+ is a cation, the electron configuration of K+ has one less electron than that of K. This means one electron needs to be removed from the outer shell, giving the configuration, 1s22s22p63s23p6. This configuration is the same as the noble gas (Ar), which makes the K+ cation quite stable.
