Thus, following the rules on how to fill the orbitals, the electronic configuration of iron (for example) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 , and it is abbreviated form [Ar] 4s2 3d6.

Which element has the ground state electron configuration 1s22s22p63s2?

element Silicon

What is the highest occupied energy level?

What is it meant by the highest occupied energy level in an atom? The highest occupied energy level in an atom is the electron-containing main energy level with the highest number.

Which of the following is the correct electron configuration for Cr3 +?

Ar]3d3

Which is the electron configuration for an oxygen atom?

[He] 2s² 2p⁴

Which is the electron configuration for a neutral atom in the ground state?

We add electrons to fill the outermost orbital that is occupied, and then add more electrons to the next higher orbital. The neutral atom chlorine (Z=17), for instance has 17 electrons. Therefore, its ground state electronic configuration can be written as 1s22s22p63s23p5.

Which neutral atom is isoelectronic with O +?

N

What is the full electron configuration for K?

[Ar] 4s¹

Which if any is the ground state electron configuration for I?

The ground state electron configuration of ground state gaseous neutral iodine is [Kr]. 4d10. 5s2. 5p5 and the term symbol is 2P3/2.

Does SI have 4 energy levels?

Silicon is composed of 14 electrons, 14 protons, and (in most cases) 14 neutrons. In its ground state, silicon has two electrons in the n = 1 energy level, eight in the n = 2 energy level, and four in the n = 3 energy level, as shown on the energy diagram to the left.
