Antimony, symbol Sb has an atomic number of 51. This is the number of protons in the nucleus of an atom of Sb, and in a neutral atom it is also the number of electrons. The ground state electron configuration for antimony is:
1s22s22p63s23p63d104s24p64d105s25p3
The ground state electronic configuration of an element X can be determined by using the periodic table. Each element has a unique arrangement of electrons in its atoms. For example, the ground state electronic configuration of carbon (C) is 1s2 2s2 2p2.
Antimony is a solid metalloid.
An atom of antimony in its ground state has 3 unpaired electrons.
The ground state electronic configuration of aluminum is [Ne] 3s2 3p1.
The symbol for sulfur is S. Its electron configuration is 1s22s22p63s23p4
The ground state electronic configuration for sodium is 1s^2 2s^2 2p^6 3s^1. This means that sodium has two electrons in the 1s orbital, two electrons in the 2s orbital, six electrons in the 2p orbital, and one electron in the 3s orbital.
The electron configuration of 1s22s22p3s1 is not the ground state electron configuration of any element. This configuration contains 8 electrons, which in the ground state would be oxygen. The ground state configuration of oxygen is 1s22s22p4.
The most likely electron configuration for a sodium ion (Na+) in its ground state is 1s2 2s2 2p6. This configuration represents the electronic structure of a sodium atom that has lost one electron to become a sodium ion, achieving a stable octet configuration similar to that of a noble gas.
The ground state electronic configuration of a bromine atom is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5. It has 35 electrons distributed in different energy levels and sublevels according to the Aufbau principle.
The electron configuration of sodium in its ground state is 1s2 2s2 2p6 3s1. This is not an excited state configuration, as the electrons are in their lowest energy levels available in the atom. Excited states occur when electrons are in higher energy levels than the ground state configuration.
[Xe] Normally the electronic configuration for Barium would be [Xe] 6s2, but since you want it for Ba2+, you're missing two electrons. You get rid of the 6s2 and get [Xe].
The ground state electron configuration for nitrogen is [He]2s2.2p3.
