How do you write the electron configuration for potassium?
The full electron configuration of Potassium (K) is 1s22s22p63s23p64s1. The abbreviated form – [Ar]4s1 – means the electron configuration of Argon (Ar), plus one electron in the 4s orbital. Argon has 18 electrons. The one additional electron configuration completes the picture for 19 electrons of Potassium.
What element has the electron configuration 3s23p4?
According to the periodic table, this element is sulfur.
Why potassium electron configuration is different?
According to octet rule, the outermost shell of an atom can accommodate maximum 8 electrons (except K shell which can accommodate maximum 2 electrons). Hence, the electronic configuration of potassium is 2,8,8,1 and not 2,8,9.

Why in potassium the 19th electron enters into 4s subshell instead of 3d Subshell?
– The energy of 4s subshell is lower than the 3d subshell. – According to the Afbau principle, the subshell with lower energy must be filled first. – Hence, the 19th electron of potassium enters into 4s subshell instead of 3d subshell.
What are the quantum numbers for the last electron in potassium?
Explanation: The four quantum numbers for an atom refer to the state of the valence or outermost electron. For a potassium atom, the electron configuration is 1s22s22p63s23p64s1 , which means that n=4 .
Which is the correct electron configuration for potassium?
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 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1.
How to write the electron configuration for sulfur ( S )?
How to Write the Electron Configuration for Sulfur (S) In order to write the Sulfur electron configuration we first need to know the number of electrons for the S atom (there are 16 electrons). When we write the configuration we’ll put all 16 electrons in orbitals around the nucleus of the Sulfur atom.
How many electrons can the p orbital hold?
The p orbital can hold up to six electrons. 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 remaining four electrons. Therefore the sulfur electron configuration will be 1s22s22p63s23p4.
