What is the electron pair geometry of Br3?
The electron pair geometry of Br3 (tribromide ion) is trigonal planar. This is due to the presence of three bromine atoms bonded to a central bromine atom, with no lone pairs on the central atom. The arrangement minimizes electron pair repulsion according to VSEPR (Valence Shell Electron Pair Repulsion) theory.
How many lone pairs of electrons are there in the ClO3- ion?
Chlorine (nucleus) has 1 lone pair and 3 polar-covalent bonding pairs (the shared pairs with O). Each oxygen (nucleus) has 3 lone pairs and 1 polar-covalent bonding pair (the shared pair with Cl)
Is F- a ligand?
Yes, the fluoride ion (F⁻) can act as a ligand. It is a negatively charged ion that can donate a pair of electrons to a metal center, forming coordinate covalent bonds. As a ligand, F⁻ can coordinate with various metal ions in coordination compounds, influencing their properties and reactivity.
What is the electron pair geometry for io2?
The electron pair geometry for the iodate ion (IO2) is trigonal planar. This is because the central iodine atom is surrounded by three areas of electron density: two bonding pairs from the iodine-oxygen bonds and one lone pair. The arrangement of these electron pairs minimizes repulsion, resulting in a trigonal planar shape.
Why is electron affinity expressed as a positive number in calculating energy of ion pair formation?
Electron affinity is expressed as a positive number in the context of calculating the energy of ion pair formation because it represents the energy released when an electron is added to a neutral atom, resulting in the formation of a negatively charged ion. This process is exothermic, meaning it releases energy, which is why the value is positive in calculations. By convention, positive values indicate energy release, facilitating the understanding of energy changes during ion formation. Thus, when considering the overall energy balance in ion pair formation, the electron affinity contributes positively to the total energy released.
What is an ion pair and how does it form in chemical reactions?
An ion pair is a pair of ions, one positively charged and one negatively charged, that are attracted to each other due to their opposite charges. In chemical reactions, ion pairs can form when a molecule loses or gains an electron, creating ions with opposite charges that then attract each other to form a pair.

What is parent ionization energy?
It is the energy that is needed for ionization to happen. The parent ion is the ion before ionization, after it is known as the daughter ion
What is the number of lone electron pairs in the NO2- ion?
The NO2- ion has one lone electron pair.
What Correctly represents an ion pair and a correct formula for the ionic compound the ions form?
An ion pair is made up of a positively charged ion (cation) and a negatively charged ion (anion) that are attracted to each other due to their opposite charges. For example, in the ionic compound sodium chloride (NaCl), the ion pair consists of the sodium cation (Na+) and chloride anion (Cl-). The correct formula for the compound they form is NaCl.
Why does the H plus ion act as a Lewis acid?
The H+ ion acts as a Lewis acid because it can accept a pair of electrons from a Lewis base to form a coordinate covalent bond. Due to its electron deficiency, the H+ ion is capable of accepting an electron pair, making it a strong electrophile and thus a Lewis acid.
What is meant by ion pair reagent?
An ion pair reagent is a reagent used in analytical chemistry to facilitate the formation of ionic pairs between a charged analyte and a counterion. It involves the addition of a reagent that can associate with the analyte and form a stable ion pair, which can then be selectively extracted or separated. This technique is commonly used in chromatography and extraction methods for the analysis of charged species.
Electric potential energy of an ion?
The electric potential energy of an ion is the energy stored in the electric field surrounding the ion due to its charge. It is directly proportional to the ion's charge and the electric potential at the location of the ion. This energy can be calculated using the formula: U = qV, where U is the electric potential energy, q is the charge of the ion, and V is the electric potential at that point.
