Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.removal of e- from Mg2+?
Mg-
should be exo thermic
why
Mg is more stable than Mg- and more stable = less energy so when it becomes more stable it will release energy hence exo
but removing electron is gonna require some x energy right?
or are saying ki we remove electron with some energy x then it releases energy y
y > x so exo?
no , removing e- would be spontaneous it shouldnt require any external energy , if les say removing e- would make it unstable then it would require energy
like when halogens accept e- they release energy it does not require energy to give them e-
i mean that electron is gonna be held by some force in the orbitals right? so we'll have to bring ionisation energy into action to remove it, no ?
i get that but this is about removing electron
ye a bit of energy , but that gets over ruled by sheer amount of energy released
that's what i said but I'm not sure if that actually happens
ye sometimes it might not be required but most time some energy is required
are those not two different processes then or does it happen very fast or even simultaneously that we take them as one?
its very fast we jsut take it as one
energy is overall released
do yk any example where no energy is required on removal of electron?
uhm ig where e- in outer most orbital just gets ejected by the force due to other e- s
i mean- is it even added when they themselves are ejecting it out ? ðŸ˜
idek classical mechanics does not apply on quantum level cant even totally talk about forces
quantum apply karo then
💀
do u even know what quantum mechanics is?
phsyics applicable for microscopic objects innit?
its way more complex than that , way out of scope of 12th or even collage
ik man i was just kidding and my definition is on point but it is brief and comprehensible unlike quantum itself
Exothermic
Because heat will release from the atom in this process
why

1. The electron gain enthalpies of Be and Mg are positive. What is your opinion? Justify. ... of nobles gases have large positive values. Why?
got it! btw can i take this as a general thumb rule ? Reverse of exothermic being endothermic and vice versa?
okie thanks!!
