Why formation of uni-negative ion is exothermiic process?
Because when the negative ion is form the atom evolves energy for gaining an other electron.The energy evolves in anionic process so the formation of negative ion is an exothermic process.
Is energy required or released in the formation of negative ions?
ergy is released in the formation of negative ion
What is positive ion and negative ion in NACl?
Na is positive ion,Cl is negative ion
What is ion formation?
Ion formation is the process by which an atom gains or loses electrons, resulting in a positively or negatively charged particle called an ion. This occurs when an atom gains a negative charge (anion) by gaining electrons, or gains a positive charge (cation) by losing electrons. Ions play a crucial role in chemical reactions and are important for the functioning of biological systems.
What happens to electrons during ion formation?
During ion formation, electrons are either gained or lost by an atom. When electrons are lost, a positively charged ion forms (cation), and when electrons are gained, a negatively charged ion forms (anion). This process balances the number of protons and electrons in the atom to achieve a stable electron configuration.

Why anion formation is exothermic?
During the Formation of postitve ion we have to break the force attraction between nuecleus and electron. while doing so energy is absorbed and process become endothermic.
Is energy required or released in the formation of negative ions?
ergy is released in the formation of negative ion
Why electron affinity of dinegative ion is endothermic?
When an electron is added to a dinegative ion, it is already in a very stabilized state due to the presence of two extra electrons. Adding another electron would result in electron-electron repulsions and destabilize the system, requiring energy input. This leads to an endothermic process for adding an electron to a dinegative ion.
Why formation of di and tri-negaive ions is endothermic process?
when an electron is added to an atom, uninegative ion is formed and enrgy is released. the addition of one more electron is difficult because negative charge or electronic cloud repels it strongly, to overcome this repelsion an amount of energy is needed, which is obtained by surroundings so its an endothermic reaction.
What is the difference between the formation of a positive ion and a negative ion?
positive ion forms when any electron removes from an atom and an anion called negative ion forms when an atom accepts an additional electron
Is dissociation of ammonium chloride endothermic or exothermic?
The dissociation of ammonium chloride is endothermic because energy is required to break the bonds holding the ammonium ion (NH4+) and chloride ion (Cl-) together. This process absorbs heat from the surroundings, making it endothermic.
What happens when a positive ion of the base combines with the negative ion?
When a positive ion of a base combines with a negative ion, they form an ionic compound called a salt. This reaction is known as neutralization and results in the formation of water molecules. The salt produced depends on the specific base and negative ion involved in the reaction.
Is an element with a large negative electron affinity most likely to form a positive ion a negative ion or a neutral atom?
An element with a large negative electron affinity is more likely to form a negative ion because it strongly attracts electrons to achieve a stable electron configuration. This results in the formation of negatively charged ions.
Why is the chlorine ion oxidised when it reacts at the negative electrode?
Chlorine ion is oxidized at the negative electrode because it gains electrons, which is the process of oxidation. In this case, the chlorine ion loses its extra electron to become a chlorine atom, which is an oxidation process.
What do ionic bonds form between a ion with a posative charge and a ion with negative charge?
Ionic bonds form between ions with opposite charges, such as a positive ion (cation) and a negative ion (anion). The positive ion is attracted to the negative ion, resulting in the formation of a strong electrostatic bond between them. This attraction helps to stabilize the ions and create a stable compound.
