Q) Explain why the second electron affinity is always endothermic...
the answer is
A) A negative electron is added to a negative ion and the two negative charges repel.
^^^ how does that even link to it being endothermic?? o.O

O.k I'm really sorry I can't really help.
I just learned about endothermic reactions this year haha

^^^ ur still a star gazzy

No chem help for you cause we now on the break. No school, no help

^^^ lolz xD
i have my finalz in 2 weeks

liar, almost all schools are on break now even if your school go by quarter, it's still on break

^^^ yh i start on tuesday...
but i still need help!

oh really. Sorry I can't help. I'm only good at math!

Thanks Marwa,your a star too haha

Marwa sorry to tell you this but your book is stupid. That is the worst explanation ever. The reason why it is exothermic is because it energy is released when an electron is taken in by a substance, just liek when 2 elements combine to form a compound it is an exo reaction.

^^^^^^^^^^^there you go, the chem guy is back
