Electron Configuration Of Sodium In Ground State. The ground state electronic configuration of sodium is 1s22s22p63s1 1 s 2 2 s 2 2 p 6 3 s 1 the excited electronic configuration is written when an electron is excited and jumps into a higher. Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure.
Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure. The first excited state is obtained by promoting a 3s electron to the 3p orbital to obtain the 1s 2 2s 2 2p 6 3p 1 configuration abbreviated as the 3p level. The chemical symbol for sodium is na.
Since 1s can only hold two electrons the next 2 electrons for sodium go in the 2s orbital.
When we write the configuration we ll put all 11 electrons in orbitals around the nucleus of the sodium atom. The first excited state is obtained by promoting a 3s electron to the 3p orbital to obtain the 1s 2 2s 2 2p 6 3p 1 configuration abbreviated as the 3p level. We gots z 11 that starts on the third period with a single 3s electron. Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure.
