Question: What element is the electron configuration representing?
1s2 2s2 2p6 3s2 3p6 4s2.
Answer: he given electron configuration: Kr stands for Krypton, Krypton’s atomic number being 1s2 2s2 2p6 3s2 3p6, which symbolizes it.
Krypton is a non-reactive chemical element with an atomic number equal to 36, indicating that each of its atomic nuclei has 36 protons and is composed of 36 electrons with various electrons placed in each of the various orbitals of the atom. It is electron configuration that expects the distribution of these 36 electrons in the different energy levels and sublevels.
Specifically, the configuration indicates that the electrons are distributed as follows: the electrons are situated as – two in the 1s, two in the 2s, six in the 2p, two in the 3s, six in the 3p, and two in the 4s orbital respectively. Such distribution depicts Krypton’s stable configuration of electrons, that is a noble gas surrounded by electrons in all three shells, attaining a completely filled outer shell. This to make it inactive chemically under normal conditions.
