endo process because it involves breaking of bonds ( requires energy thus energy from surroundings are absorbed)
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.
ergy is released in the formation of negative ion
Na is positive ion,Cl is negative ion
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.
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.
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.

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.
ergy is released in the formation of negative ion
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.
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.
positive ion forms when any electron removes from an atom and an anion called negative ion forms when an atom accepts an additional electron
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.
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.
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.
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.
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.
