Intensive and Extensive properties

In thermodynamics, properties of matter can be classified as either intensive or extensive. Intensive properties are properties that do not depend on the amount of matter present. Examples of intensive properties include temperature, pressure, density, and specific heat capacity. These properties are useful in describing the state of a system and can be used to…

Trigonal bipyramidal

Trigonal bipyramidal is a term used in chemistry to describe the shape of molecules that have five atoms or groups of atoms bonded to a central atom. The shape is named trigonal bipyramidal because it has three equatorial atoms in a plane that form an equilateral triangle, and two axial atoms above and below this…

Pyramidal

“Pyramidal” can refer to several different things depending on the context. Here are some possible interpretations: What is Required Pyramidal Chemical Bonding and Molecular Structure “Required Pyramidal Chemical Bonding” is not a standard term in chemistry. However, based on the context, it appears that you may be referring to a type of chemical bonding or…

Dipole moment

A dipole moment is a measure of the polarity of a molecule. It is defined as the product of the magnitude of the partial charges on two atoms in a molecule and the distance between them. In other words, a dipole moment is the separation of positive and negative charges in a molecule, which results…

Polarity in molecules

In chemistry, polarity refers to the separation of electric charge within a molecule or compound. A molecule can be polar or nonpolar depending on the electronegativity of its constituent atoms and the molecular geometry. When two atoms with different electronegativities are bonded together, the electron pair in the bond is not shared equally, resulting in…

Hydrogen bond

A hydrogen bond is a type of intermolecular force that occurs between a hydrogen atom bonded to an electronegative atom, such as nitrogen, oxygen, or fluorine, and another electronegative atom. The hydrogen atom has a partial positive charge due to the electron-withdrawing effect of the more electronegative atom, while the other atom has a partial…

Molecular orbital energy diagrams for homonuclear diatomic species (up to Ne2)

Hybridisation involving s, p and d orbitals only

Hybridization is a concept in chemistry where atomic orbitals combine to form hybrid orbitals that have different shapes and energies from the original atomic orbitals. The most common types of hybridization involve s and p orbitals, but d orbitals can also be involved in certain cases. Hybridization involving only s, p, and d orbitals is…

Orbital overlap and Covalent bond

Orbital overlap is a concept in chemistry that refers to the interaction between two or more atomic orbitals when they come together to form a chemical bond. When atoms bond together, their atomic orbitals can interact in a way that allows them to share electrons and create a stable molecule. Covalent bonding is a type…

Pauli’s exclusion principle and Hund’s rule

Pauli’s exclusion principle and Hund’s rule are both fundamental principles of quantum mechanics that describe the behavior of electrons in atoms. Pauli’s exclusion principle states that no two electrons in an atom can have the same set of quantum numbers. In other words, each electron in an atom must have a unique combination of values…
