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 else can I help you with?
Is ionization an exothermic or endothermic process?
Ionization is typically an endothermic process because energy is required to remove an electron from an atom or molecule, resulting in the formation of ions. This energy requirement is necessary to overcome the attractive forces between the positively charged nucleus and the negatively charged electron.
When solid lead chloride dissolves in hot water is this endothermic or exothermic?
The dissolution of solid lead chloride in hot water is an endothermic process because energy is absorbed to break the bonds holding the solid together. This energy is needed for the solid to transition into freely moving ions in solution.
To dissolve an ionic solid in water, you must first disrupt the ionic bonds holding the ionic lattice together This is an endothermic process Yet many ionic solids have an exothermic heat of solutio?
In order to dissolve an ionic solid in water, the endothermic process of breaking the ionic bonds holding the lattice together is followed by the exothermic heat of solution when the ions are hydrated by water molecules. The overall process can be exothermic or endothermic depending on the relative magnitudes of the energy changes involved in breaking the ionic bonds and hydrating the ions.
Is obtaining lime from limestone exothermic?
The hydratation of concentrated OH- and Na+ ions (by dilution) is exothermic, it gives an energetically prefered state of matter.(Hydratation is the extra surrounding of the ions by polar water molecules of the solvent).
Is base an endothermic or an exothermic?
Base dissociation is an endothermic process, meaning that it requires energy in the form of heat to occur. The energy is needed to break the bonds within the base molecule and allow it to dissociate into ions.
Is ionization an exothermic or endothermic process?
Ionization is typically an endothermic process because energy is required to remove an electron from an atom or molecule, resulting in the formation of ions. This energy requirement is necessary to overcome the attractive forces between the positively charged nucleus and the negatively charged electron.
How Compare the formation of positive ions with the formation of negative ions in terms of energy changes?
The formation of positive ions typically involves the loss of one or more electrons from an atom, which requires energy input to overcome the attraction between the electrons and the nucleus; this energy is called ionization energy. In contrast, the formation of negative ions occurs when an atom gains one or more electrons, a process that usually releases energy, known as electron affinity, as the added electron is attracted to the nucleus. Thus, while the formation of positive ions is endothermic (requiring energy), the formation of negative ions is exothermic (releasing energy).

Why the process of making ions allows ionic bonding to happen?
The process of making ions involves the transfer of electrons from one atom to another, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions). These oppositely charged ions are attracted to each other due to electrostatic forces, leading to the formation of an ionic bond. This bond is strong because of the attraction between the opposite charges of the ions.
To dissolve an ionic solid in water you must first disrupt the ionic bonds holding the ionic lattice together This is an endothermic process Yet many ionic solids have an exothermic heat of solutio?
When an ionic solid dissolves in water, the ionic bonds holding the lattice together are broken. This process requires energy, making it endothermic. However, when ions are hydrated in water, the formation of new bonds between the ions and the water molecules releases energy, resulting in an exothermic heat of solution.
What is the general term for processes such as the conversion of fluorine atoms to floride ions?
The general term for the conversion of fluorine atoms to fluoride ions is "ionization" or "ion formation." This process involves the gain or loss of electrons, resulting in the formation of ions with a positive or negative charge.
What is the chemical equation for carbonate rock formation?
The chemical equation for carbonate rock formation involves the precipitation of calcium carbonate (CaCO3) from dissolved bicarbonate ions (HCO3-) in water. This process typically occurs in oceans or lakes where calcium ions (Ca2+) and bicarbonate ions are present, leading to the formation of carbonate rocks like limestone or dolomite.
Is the formation of ionic compounds exo or endothermic?
The formation of ionic compounds is typically exothermic, meaning it releases energy in the form of heat. This is because the strong electrostatic attractions between positively and negatively charged ions result in a more stable state compared to the individual atoms.
Why is the electrolysis of aluminium oxide endothermic?
The electrolysis of aluminium oxide is endothermic because it requires a significant amount of energy to break the strong bonds present in the compound. This process involves separating the aluminum from the oxygen, which requires input of energy to overcome the electrostatic forces holding the ions together. Additionally, the high melting point of aluminum oxide necessitates the use of high temperatures to facilitate the electrolysis process, further contributing to its endothermic nature.
