addition of one or more electrons to an atom will a) increase size of atom, decrease ionization energy and increase electron affinity b) decrease size of the atom, increase ionization energy and increase the electron affinity c) increase size of the atom, increase ionization energy and decrease the electron affinity d) decrease siza of atom, decrease ionization energy and decrease electron affinity

answer; i believe that the correct answer is (a) potassium(k)

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
