Why does electron affinity tend to become more exothermic as you move right across a period?
Electron affinity tends to become more exothermic as you move right across a period because the effective nuclear charge increases, leading to a stronger attraction between the nucleus and the incoming electron. This results in a more stable electron configuration and a release of energy.

Which group of elements has the highest electron affinity?
Halogens have the highest electron affinity among all elements. This is because halogens have a strong tendency to gain an electron to achieve a full outer energy level and become stable.
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
Is the formation of a stable ionic compound exothermic?
For an element to lose an electron, that electron must become excited to the point it can escape the attractive force. This requires a net energy input, making it endothermic.
Why electron gain enthalpy of Mg and P are almost zero?
The electron gain enthalpies of Mg and P are almost zero because both elements are inherently stable in their neutral state (Mg+ and P-). They have a full valence shell configuration, which makes them reluctant to gain additional electrons and become more stable. This results in low electron affinity values for both elements.
Which group of elements tend to give up electrons and become positive?
Group 1 elements, also known as alkali metals, tend to give up electrons and become positive ions due to their low ionization energy and affinity to lose an electron to achieve a stable electron configuration.
Why the electron affinity is important?
Electron affinity for an atom is important to make it as a molecule.where atom is a small single one and molecule is the combination of two or more atoms.electron affinity is just a desire for attraction of electron by the atom.for example : We should have some affection for others to become their close relation like friends and live together in the same way a single atom should have desire [that is framed as ELECTRON AFFINITY] for electrons to be attached to form molecule
Which group of elements has the highest electron affinity?
Halogens have the highest electron affinity among all elements. This is because halogens have a strong tendency to gain an electron to achieve a full outer energy level and become stable.
Why the value of electron affinity is positive for noble gases?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. They will not accept any more electrons and hence they have positive electron affinity.
What part of the atom is able to be lost or gained?
the energy is require to remove an electron from an atom (ionization energy) but when electron is absorbed in an atom energy is released (electron affinity) however 2nd electron affinity is endothermic ,energy is require.
What is electron gen enthalpy?
Electron Gain Enthalpy is the amount of Energy released when an isolated gaseous atom accepts an electron to become a monovalent gaseous anion.For Example:Atom(gas) +Electron ---->Anion(gas) +Energy(Electron Gain Enthalpy)
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.
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 liquid to a gas endothermic or exothermic?
It is exothermic. The gas must release energy to its surrounding to become a liquid.
Is the formation of a stable ionic compound exothermic?
For an element to lose an electron, that electron must become excited to the point it can escape the attractive force. This requires a net energy input, making it endothermic.
Why electron gain enthalpy of Mg and P are almost zero?
The electron gain enthalpies of Mg and P are almost zero because both elements are inherently stable in their neutral state (Mg+ and P-). They have a full valence shell configuration, which makes them reluctant to gain additional electrons and become more stable. This results in low electron affinity values for both elements.
Why are halogens oxidising agents?
Halogens are strong oxidizing agents because they have a high electron affinity and can easily accept electrons from other atoms or ions, causing them to be reduced in the process. They have a high tendency to gain electrons to achieve a stable electron configuration, making them effective at oxidizing other substances by removing their electrons.
Which group of elements tend to give up electrons and become positive?
Group 1 elements, also known as alkali metals, tend to give up electrons and become positive ions due to their low ionization energy and affinity to lose an electron to achieve a stable electron configuration.
