chem HELP!!! ionization (1 Viewer)

[White-Doggy]

Does anybody noe in depth about how ionization occurs? as in wot is the maximum electrons an atom loses? does it just lose as much until it becomes stable (law of octave) or does it keep losing until theres no more electrons?


for eg.

mg ---> mg + + e- (first ionisation)

mg+ ----> mg +2 + e- (2nd ionisation)

mg +2 ----> mg + 3 + e- (3rd ionisation)



does magnesium just stop here because its stable now mg 2+ or is it susceptible to lose more?

 

[undalay]

It'd stop because its stable

They all try to achieve stable electron configuration towards the configuration of the noble gases. Ionisation energy is differnt in each shells and the amount of electrons left.

thnx guys...here comes another dilemma


yeah thats wot i thort, but then, why does lithium have 3 successive ionisations?
shouldnt it just have 2 then it becomes stable?


Li --------> Li+ + e- (first ionisation)



Li+ ------> Li 2+ + e- (2nd ionisation)

ionisation can occur as long as there is enough energy (hence "first ionisation energy"). i mean, even noble gases can be ionised, despite having the "wanted configuration".

as for the actual limit of how ionised an atom can get, i have no idea (not HSC). i would imagine there is no limit, as long as you have the needed energy.

ohh c= that makes more sense. thnx loads everybody ^^,
