# What is the most significant distinction between atomic orbital theory and molecular orbital theory?

Orbitals can hold a maximum of two electrons. The main difference between atomic and molecular orbital is that the electrons in an atomic orbital are influenced by one positive nucleus, while the electrons of a molecular orbital are influenced by the two or more nuclei depending upon the number of atoms in a molecule.

Valence bond theory can only be applied for diatomic molecules whereas molecular orbital theory can be applied on polyatomic molecules. In valence bond theory, bonds are localized to two atoms and not molecules while in molecular orbital theory, bonds are localized to both two atoms and molecules.

Likewise, what are the postulates of molecular orbital theory? Main postulates of this theory are Atomic orbitals of comparable energy and proper symmetry combine together to form molecular orbitals. The movement of electrons in amolecular orbital is influenced by all the nuclei of combining atoms.

Likewise, people ask, what is atomic orbital theory?

In atomic theory and quantum mechanics, an atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom’s nucleus.

## What does an sp3 orbital look like?

P orbitals are shaped like figure eights and electrons in p orbitals are slightly farther away from the nucleus than electrons in s orbitals. The sp3 orbital is 25% s character and 75% p character (1 2s orbital, + 3 2p (2px, 2py, 2pz).

What does the molecular orbital theory describe?

Molecular orbital theory. In chemistry, Molecular orbital (MO) theory is a method for describing the electronic structure of molecules using quantum mechanics. Electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole molecule.

### What is basic postulates of molecular orbital theory?

Main postulates of this theory are Atomic orbitals of comparable energy and proper symmetry combine together to form molecular orbitals. The movement of electrons in amolecular orbital is influenced by all the nuclei of combining atoms.

### What are the main points of valence bond theory?

Valence Bond theory describes covalent bond formation as well as the electronic structure of molecules. The theory assumes that electrons occupy atomic orbitals of individual atoms within a molecule, and that the electrons of one atom are attracted to the nucleus of another atom.

### What is bond order in molecular orbital theory?

In molecular orbital theory, bond order is also defined as the difference, divided by two, between the number of bonding and antibonding electrons; this often, but not always, yields the same result. Bond order is also an index of bond strength, and it is used extensively in valence bond theory.

### What is the basic principle of valence bond theory?

The basic principle of VB theory is that a covalent bond forms when orbitals of two atoms overlap and the overlap region, which is between the nuclei, is occupied by a pair of electrons.

### What is the shape of d orbital?

The d orbital is a clover shape because the electron is pushed out four times during the rotation when an opposite spin proton aligns gluons with three spin-aligned protons.

14 electrons

### Why can an orbital only have 2 electrons?

An orbital contains only 2 electrons to make the net magnetic moment of that orbital zero This is because for each orbital the value of spin quantum number is 2 (+1/2 , -1/2). So only two electrons one with spin +1/2 (clockwise) and other with spin -1/2 (counterclockwise) can occupy an orbital.

### What are the 4 atomic orbitals?

There are four types of orbitals that you should be familiar with s, p, d and f (sharp, principle, diffuse and fundamental). Within each shell of an atom there are some combinations of orbitals.

### What does an orbital diagram look like?

Orbital diagrams are pictorial descriptions of the electrons in an atom. Three rules are useful in forming orbital diagrams. According to the Auf Bau Principle, each electron occupies the lowest energy orbital. You jump up a little bit in energy and we get the 2s orbital that make it the 2p sublevel.
