![]() ![]() ![]() The name of the compound ends with the -ide term, which means it is a binary compound and an anion. Triiodide ion is the iodine compound with the formula (I3-). Sigma bond is a stronger bond and can exist independently, but the pi bond is weaker and cannot exist independently. Sideways overlapping leads to a weaker bond with high energy and less stability. The type of overlapping observed between the orbitals is sideways overlapping or parallel overlapping. Pi bond: Pi bond is a covalent bond formed by the sharing of electrons present in the orbitals. This type of overlapping leads to a strong overlapping of orbitals and hence a stronger bond, which is a stable bond with minimum energy. ![]() The type of overlapping observed between the orbitals is head-on overlapping or inter-axial overlapping. Sigma bond: The sigma bond is a covalent bond formed by the sharing of electrons present in the orbitals. Bonds formed between the covalently bonded atoms can be of two types: sigma bond and pi bond. Hybridization helps in knowing the types of bonds formed between the two elements. Hybridization occurs in the central atom to get the orbitals of equal energy, and the overlapping of orbitals with equal energy is effective. Hybridization occurs in the central atom, where the electrons in the valence shell exist in orbitals of different energy and shape. Hybridization does not occur in all covalent molecules and occurs in heteroatomic molecules like methane, ammonia, etc. Hybridization occurs in covalent molecules and between the atomic orbitals of the central atom. In a covalent molecule, the element with a high valency is considered the central atom. Hybridization occurs in the central atom only. Hybridization is the phenomenon that involves intermixing of atomic orbitals of the central atom that differ in energy and their re-distribution to an equal number of hybrid orbitals of equal shape and energy. These are far from the nucleus and can easily involve in the bonding with other elements. Valence electrons are those that are present in the outermost shell of an atom. Usually, elements combine with other elements only with the help of valence electrons. Elements that are unstable combine usually with other elements either by losing or gaining or sharing electrons. ![]()
