When an atom loses one or more electrons from its outermost electron shell during a chemical reaction?

you should just be yourself and not let any body tell you other wise.

explanation:

why?

because if they don't love you for your self then they don't deserve you.

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.
