Oxygen ground state electronic configuration, 19

Give the ground-state electron configuration for each of the following elements (a) Oxygen (b) Silicon (c) Sulfur... 

In practice both natural and synthetic crystals are oxygen deficient, leading to donor levels approximately 0.1 eY below the bottom of the conduction band and consequently to n-type semiconductivity. Doping the crystal with group V elements also induces n-type semiconductivity the usual dopant is antimony. The ground state electronic configuration of the Sb atom is 5s2p3, and when it... 

A different way to represent the ground-state electron configuration is to simply write down the occupied orbitals and to indicate the number of electrons in each orbital. For example, the electron configuration for oxygen is Is2 2s2 2p. ... 

The reaction of a radical with oxygen, a diradical in its ground state electronic configuration, is another example of two radicals reacting with each other. In this case, the reaction of O2 with X forms a new radical, thus preventing X from reacting with an organic substrate. 

The ground-state electronic configuration, in the localized valence-bond description, can be written is lp oh. It can be deduced that the corresponding delocalized MO configuration is la 2a 3a l/7 1/)2 rli- The 2>a and l/>2 are predominantly 0-H bonding orbitals, while the h and 2a are predominantly oxygen lone pairs. 

Figure 2.9 The ground-state electron configuration of O2. Each oxygen atom contributes eight electrons, and each orbital up to the 7r2p set contains paired electrons. The last two electrons occupy separate tt 2p orbitals, with parallel spins...

Water. The oxygen-atom ground-state electron configuration is l 2s 2p with an unpaired electron in each of the AOs 2py and 2p. We thus assume that these AOs along with the hydrogen Is AOs will form electron-pair bonds. The three possible ways of pairing these four AOs to get covalent structures are shown in Hg. 15.18. 

The ground-state electronic configuration of H2O, with eight valence electrons (two from the hydrogens. 2Alp or six from oxygen), is therefore...
