Argon/Electron configuration
What is the electronic configuration for an element with 18 electrons?
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.
What is electronic configuration of AR 18 as per Aufbau principle?
D 1s22s22p63s23p63d104s24p6. Hint: The atomic number of argon is 18. We can write the electronic configuration by the help of the atomic number and filling up those electrons in s, p, d and f-orbitals. The number of electrons that can be accommodated in s, p, d and f-orbitals are 2, 6, 10 and 14 respectively.
What is the electronic configuration of oxygen Z 8 and argon Z 18?
Looking at the periodic table, you can see that Oxygen has 8 electrons. Based on the order of fill above, these 8 electrons would fill in the following order 1s, 2s and then 2p. So Oxygen’s electron configuration would be O 1s22s22p4.

What is the electronic configuration of oxygen Z 8?
If we look at the element after Nitrogen in the same period, Oxygen (Z = 8) its electron configuration is: 1s2 2s2 2p4 (for an atom). Oxygen has one more electron than Nitrogen and as the orbitals are all half filled the electron must pair up.
