Question

formation of cation is endothermic where formation of anion is exothermic. justify

Answer 1

To form cations, metals lose electrons and to loose electrons energy is required hence it is endothermic

To form anions, non-metals loose electrons and thus heat is liberated and hence exothermic

Answer 2

${\huge{\boxed{\mathbf{\red{♡ANSWER♡}}}}}$

• .Absorption of energy in the formation of cation .
• So it is endothermic x -----> ${x^+}$ +${e^-}$.
• Loss of energy in the formation of anion.
• So it is exothermic .x+${e^-}$---->${x^-}$.
