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.

Where is NAD made?
NADPH is made during photosynthesis after light is absorbed.
Water is absorbed from what during digestion?
Water is absorbed from the large intestine into the bloodstream during digestion.
What is a proton in the nucleus converted into what during electron capture?
During electron capture, an electron and proton combine and are converted to a neutron.
Energy is absorbed when a nucleus is split during a nuclear reaction?
No, energy is released rather than absorbed
Is energy absorbed or released during freezing?
Energy is released during freezing.
If energy is absorbed during electron sharing the process is said to be?
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.

During electron capture, an electron and proton combine and are converted to a neutron.
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 are three change of state in which energy is absorbed?
Energy is absorbed during melting, boiling and sublimation.
Is energy absorbed during evaporation?
yes
During meiosis two successive divisions are responsible for the formation of?
There are two successive divisions that are responsible for the formation of eukaryotic cells. This is what produces two daughter cells.
