There is a greater repulsive force from the negatively charged anion, thus causing the addition of successive electrons to be electrically unfavorable. Energy is necessary to overcome the electrostatic repulsion, making additional electron affinities endothermic.
For the same reason, the noble gases and nitrogen absorb energy even for their first ionization energy. Greater stability = energy released. It requires energy to disrupt that stability.
Energy is absorbed during successive electron affinities because each additional electron added to an atom or ion creates increased electron-electron repulsions, making it less stable and thus requiring more energy to add the next electron. This leads to an overall increase in energy as more electrons are added.

What can be said of the amount of energy that an electron absorbs when it is excited compared to the amount of energy that it releases when it returns to ground state?
When an electron is excited, it absorbs a specific amount of energy to move to a higher energy state. When it returns to its ground state, it releases this absorbed energy in the form of electromagnetic radiation. The energy released is equal to the energy absorbed during excitation, following the principle of conservation of energy.
What is a proton in the nucleus converted into what during electron capture?
During electron capture, a proton in the nucleus is converted into a neutron. This process occurs when an electron combines with a proton in the nucleus, resulting in the emission of a neutrino.
Is energy absorbed or released during freezing?
Energy is released during freezing.
Is energy released during fission but absorbed during fusion?
Energy is released during fusion and fission.
What has to happen for a disaccharide to be absorbed?
Hydrolysis must occur before a disaccharide can be absorbed into the bloodstream. A water molecule is added during this process.
Why are most electron affinities negative numbers?
Most electron affinities are negative because when an electron is added to an atom, energy is released. This released energy causes the system to become more stable, resulting in a negative change in energy. The negative sign indicates that energy is released during the process.
If energy is absorbed during electron sharing the process is said to be?
endothermic
If you make the electron jump downward then return it to the outer ring what do you notice about the photon released or absorbed?
When an electron jumps downward to a lower energy state in an atom, it releases energy in the form of a photon which is emitted. When the electron returns to the outer ring, it absorbs energy in the form of a photon. The energy of the photon absorbed is equal to the energy of the photon released during the downward jump.
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.

How many photons are absorbed during light reaction?
During the light reactions of photosynthesis, hundreds to thousands of photons may be absorbed by a single chlorophyll molecule in the reaction center of a photosystem. These photons provide the energy needed to drive the electron transport chain and convert light energy into chemical energy in the form of ATP and NADPH.
What thing is absorbed by chlorophyll during photosynthesis?
Light is absorbed during photosynthesis. (That's the meaning of photo!)
WHAT HAPPENS IN THE PHOTOSYSTEM 2 protein when it is hit by a photon of light?
In photosystem II, the photon of light is absorbed by a pigment molecule, which causes an electron to become excited. This electron is then passed through a series of electron carrier molecules, creating a flow of electrons used to generate ATP and NADPH during the light-dependent reactions of photosynthesis.
What color wavelengths are absorbed during photosynthesis?
The green color is being absorbed
What are three changes of state during which energy is absorbed?
The three changes of state during which energy is absorbed is: conduction, convection, & radiation.
What is a proton in the nucleus converted into what during electron capture?
During electron capture, a proton in the nucleus is converted into a neutron. This process occurs when an electron combines with a proton in the nucleus, resulting in the emission of a neutrino.
How does insulator get charge by rubbing easier than conductor?
When insulators are rubbed, charges are transferred through a process called triboelectric charging. Insulators have high electron affinities, making it easier for them to gain or lose electrons during rubbing. Conduction, on the other hand, requires mobile electrons which are more restricted in insulators compared to conductors.
