Answer:
k
Explanation:
electron affinity (EA) depends on various factors like effective nuclear charge (enc) , size of the atom, ellipticity of sub-shell (ep) , nature of configuration.
more is the enc more will be the EA
more is the size less will be the EA
more valance shell ellipticity (closer to the nuclei) more will the EA ( all given element posses P orbital in the valance shell)
Sulfuric acid is the answer
Answer:
When a sodium atom transfer over to a chlorine atom it forms a sodium cation and a chloride anion.
Explanation:
During that time both of the ions would have completely valence shells and energy wise are more stable, the reaction is usually VERY exothermic (Release of heat) which usually produces a bright yellow light.
