This phenomenon is explained by s-p mixing. All the elements in the second period before oxygen have the difference in energy between the 2s and 2p orbital small enough, so that s-p mixing (combination) can occur lowering the energy of the σ(2s) and σ*(2s) and increasing the energy...
Quantum Beats in the Electric-Field Mixing of the n=2 States of Atomic Hydrogen The Lyman-alpha " Stark beats " produced by the coherent decay of the perturbed 2s and 2p states has been extensively studied, for example in collisions of electrons with atoms, 1 in heavy particle collisions 2...
Sp3 hybridisation is formed when one 2s orbital blends with three 2p orbitals to form hybridised orbital structure. The formed structure is a tetrahedron, which means 4 hybrid orbitals with the same features. These sp3 hybrid orbitals have the same level of energy and are delocalised. In sp3...
What is the hybridization of the orbitals of the N atom in NO2+?Which of the following orbitals has the lowest energy? a. 1a orbital b. 1p orbital c. zero orbital d. 1s orbitalThere are how many different p orbitals?In a hydrogen atom, the 2s and 2p orbitals have the same ...
Why copper is diamagnetic while it has one unpaired s electron? What is the value of ece of copper? The electronic configuration for the noble gas is (a) 1s2, 2s2 2p6 (b) Is2, 2s2 2p5 (c) Is2, 2s2 2p6, 3s2 3p6, 4s2 (d) Is2, 2s2. How many electrons are there in 1C...
ferrocene has the formula Fe(C5H5)2 and cosists of two cyclopentadienyl rings coordinated to the iron center via "eta" 5 bonding. The compound is quite stable owing to molecular orbital arguments (ie the 18 electron rule). ferrocenium is the positive ion of ferrocene where iron is in the...
The presence of the small absorption tail indicates the substitutional doping of nitrogen replacing the oxygen atoms in the Ti[O.sub.2] lattice; as a result, an impurity band (mixing of N2p states with O2p states) is formed above the valence band of Ti[O.sub.2]. Chelated Nitrogen-Sulph...
