removal of e- from Mg2+?
Ishizora

Mg-
Gamertug

should be exo thermic
Ishizora
IshizoraOP•7mo ago
why
Gamertug
Gamertug•7mo ago
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?
Gamertug

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
Gamertug
Gamertug•7mo ago
ye a bit of energy , but that gets over ruled by sheer amount of energy released
Ishizora
IshizoraOP•7mo ago
that's what i said but I'm not sure if that actually happens
Gamertug
Gamertug•7mo ago
ye sometimes it might not be required but most time some energy is required
Ishizora
IshizoraOP•7mo ago
are those not two different processes then or does it happen very fast or even simultaneously that we take them as one?
Gamertug
Gamertug•7mo ago
its very fast we jsut take it as one energy is overall released
Ishizora
IshizoraOP•7mo ago
do yk any example where no energy is required on removal of electron?
Gamertug
Gamertug•7mo ago
uhm ig where e- in outer most orbital just gets ejected by the force due to other e- s
Ishizora
IshizoraOP•7mo ago
i mean- is it even added when they themselves are ejecting it out ? 😭

idek classical mechanics does not apply on quantum level cant even totally talk about forces
Ishizora
IshizoraOP•7mo ago
quantum apply karo then
Gamertug
Gamertug•7mo ago
💀 do u even know what quantum mechanics is?

phsyics applicable for microscopic objects innit?
Gamertug
Gamertug•7mo ago
its way more complex than that , way out of scope of 12th or even collage
Ishizora
IshizoraOP•7mo ago
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

got it! btw can i take this as a general thumb rule ? Reverse of exothermic being endothermic and vice versa?
