The given conditions should be satisfied by atomic orbitals of form molecular orbitals:1. The combining atomic orbitals must have an equivalent or nearly an equivalent energy. This means that during a homonuclear...
When two dissimilar atoms having different electronegativities combine to form a covalent bond, the bond pair of electrons are not shared equally. The bond pair shifts towards the nucleus of the atom having greater el...
Electronegativity is the ability of an atom in a chemical compound to attract a bond pair of electrons towards itself. The electronegativity of any given element is not constant. It varies according to the element to...
Bond strength represents the extent of bonding between two atoms forming a molecule. The larger the bond energy, the stronger is the bond and the greater is the bond order.
A chemical bond is defined as an attractive force that holds the constituents (atoms, ions, etc.) together in a chemical species. Various theories have been suggested for the formation of chemical bonds such as the el...
The tendency of an isolated gaseous atom to accept an electron is measured by electron gain enthalpy, whereas the tendency of an atom in a chemical compound to attract a shared pair of electrons is measured by electro...
The following are the causes that cause the ionisation enthalpy of the primary group elements to fall along a group:(i) Elements' atomic sizes grow larger: The number of shells grows as we proceed down a group. As a re...
Sodium has a higher initial ionisation enthalpy than magnesium. This is mostly due to the following two factors:(a) Sodium's atomic size is larger than that of magnesium.(b) Magnesium has a higher effective nuclear char...
The energy required to remove an electron from an isolated gaseous atom in its ground state is known as ionisation enthalpy. Despite the fact that the atoms are far separated in the gaseous state, there are some attrac...
A cation possesses fewer electrons than its parent atom while maintaining the same nuclear charge. As a result, a cation's nucleus attracts electrons more than its parent atom's nucleus. As a result, a cation is small...
