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).
Which electron on an atom is the most likely one to be removed during a chemical reaction?
The valence electron, which is the electron located in the outermost energy level of an atom, is the most likely to be removed during a chemical reaction. This is because valence electrons are involved in the formation of chemical bonds and determining an atom's reactivity.
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.
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.
What part of the atom do valence electrons occur in?
Valence electrons occur in the outermost energy level, or valence shell, of an atom. These electrons are involved in the formation of chemical bonds and determining the atom's reactivity and chemical properties.
What can be removed from an atom if ionization energy is supplied?
An electron can be removed from an atom if ionization energy is supplied. Ionization energy is the energy required to remove an electron from an atom, resulting in the formation of a positively charged ion.
What is the energy sources for nuclear energy?
energy is released during atom fissure

What is the definition of lonization energy?
Ionization energy is the amount of energy required to remove an electron from a neutral atom, resulting in the formation of a positively charged ion. It is a measure of how tightly an electron is held by an atom. The higher the ionization energy, the more difficult it is to remove an electron from the atom.
Why formation of anion 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.
What do you call the energy involved when an atom loses an electron?
The amount of energy required to remove an electron form an at is the ionization energy.

What happens when heat or electrical energy is added to an atom?
When heat is added to an atom, its electrons gain energy and move to higher energy levels, causing the atom to become excited. When electrical energy is added, it can either cause the atom to gain or lose electrons, leading to the formation of ions. Both processes can result in changes to the atom's chemical properties.
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.

Thus, when considering the overall energy balance in ion pair formation, the electron affinity contributes positively to the total energy released.
Is formation of anions is exothermic process?
The formation of anions is not always an exothermic process. It can be either exothermic or endothermic, depending on the specific elements involved and the overall energy change during the process. It is important to consider the specific reaction and the energy changes associated with it.
