Molecular orbital theory explains conductivity in metals by describing how atomic orbitals combine to form molecular orbitals that are delocalized over a large number of atoms. In metals, these molecular orbitals form a band structure where the conduction band is partially filled or overlaps with the valence band, allowing electrons to move freely. This delocalization of electrons facilitates the flow of electric current, making metals good conductors. The presence of these overlapping orbitals provides a pathway for electron mobility, essential for electrical conductivity.

What is another name for the molecular orbital theory of bonding in metals?
Another name for the molecular orbital theory of bonding in metals is the band theory. Band theory describes how atomic orbitals combine to form energy bands, which explains the electrical conductivity and other properties of metals. It highlights the overlap of atomic orbitals in a solid, leading to the formation of conduction and valence bands.
How do fluorine atom form negative ions?
it depends on the molecular orbital theory
Why oxyzen is paramagnetic explain it forrm mo theory?
Oxygen is paramagnetic due to the presence of two unpaired electrons in its molecular orbital configuration. In molecular orbital theory, oxygen molecule (O2) consists of two oxygen atoms, each contributing one unpaired electron to form pi* anti-bonding molecular orbitals. These unpaired electrons make oxygen molecule paramagnetic, which means it is attracted to a magnetic field.
What is low line sigma m orbital?
A low-lying sigma molecular orbital is a symmetrical orbital formed by the overlap of atomic orbitals in a molecule. It typically has a relatively low energy level compared to other molecular orbitals, and it plays a key role in bonding between atoms in a molecule. The "m" designation in this context may refer to a molecular orbital belonging to a specific symmetry group in molecular orbital theory.
Why molecular orbital theory superior to valence bond theory and VESPR theory?
Superior is a difficult term. The latest versions valence bond theory and molecular orbital theories give similar answers. The simple old versions work from different premises- valence bond assumes localised pair bonds molecular orbital theory is better ate predicting spectroscopic properties. VSEPR is different again and focuses on the geometry around a central atom- and as such is better than both the simple versions of the other theories.
What is the role of a node in the molecular orbital theory of chemistry?
In molecular orbital theory, a node is a point in a molecular orbital where the probability of finding an electron is zero. Nodes help determine the shape and energy of the molecular orbital, influencing the chemical properties of the molecule.

Can orbital hybridization theory can describe both the shape and bonding of the molecules?
Orbital hybridization provides information about both molecular bonding and molecular shape.
What is the significance of the n2 MO diagram in molecular orbital theory?
The n2 MO diagram in molecular orbital theory is significant because it helps to explain the bonding and electronic structure of molecules. It shows how atomic orbitals combine to form molecular orbitals, which determine the stability and properties of the molecule. This diagram is crucial for understanding the behavior of electrons in chemical reactions and predicting the reactivity of molecules.
What is the difference between the homo and lumo energy levels in molecular orbital theory?
In molecular orbital theory, the HOMO (highest occupied molecular orbital) is the highest energy level that contains electrons, while the LUMO (lowest unoccupied molecular orbital) is the lowest energy level that does not contain electrons. The difference between the HOMO and LUMO energy levels determines the reactivity and stability of a molecule.

What is the significance of the molecular orbital theory in chemistry, and how can it be understood without the use of a molecular orbital diagram?
The molecular orbital theory in chemistry is significant because it helps explain the behavior and properties of molecules based on the interactions of their atomic orbitals. It allows us to predict the stability and reactivity of molecules. One way to understand molecular orbital theory without using a diagram is to think of it as a way to combine the atomic orbitals of individual atoms to form new molecular orbitals. These new orbitals can be bonding, anti-bonding, or non-bonding, which determine the overall stability and properties of the molecule. By considering the overlap of atomic orbitals and the resulting interactions, we can understand how molecules form and behave without needing a visual representation.
Why band theory based on molecular orbital theory?
Band theory is rooted in molecular orbital theory because it explains the electronic structure of solids by considering the overlap of atomic orbitals from adjacent atoms. When atoms come together to form a solid, their discrete molecular orbitals combine to create bands of energy levels, resulting in the formation of valence and conduction bands. This framework helps to characterize electrical conductivity, insulators, and semiconductors, as the distribution of electrons in these bands determines their ability to conduct electricity. Thus, band theory provides a comprehensive understanding of the behavior of electrons in crystalline solids.

What is the disadvantages of molecular orbital approach?
Some disadvantages of the molecular orbital approach include the complexity of calculations involved, especially for larger molecules, as well as difficulties in accurately predicting electronic interactions in systems with strong electron correlation. Additionally, the interpretation of molecular orbital diagrams can sometimes be challenging for non-experts due to the abstract nature of the theory.
Molecular orbital theory is based upon which model of the atom?
Molecular orbital theory determines molecular structure that the electrons are not assigned as individual bonds between atoms, however, are treated as moving under the influence of the nuclei in the whole molecule.
What theory provides information concerning both molecular shape and molecular bonding?
The VSEPR (Valence Shell Electron Pair Repulsion) theory provides information about both molecular shape and molecular bonding. It helps predict the geometric shapes of molecules based on the arrangement of electron pairs around the central atom and takes into account the repulsion between electron pairs to determine the overall molecular shape.
