chemistry - valency
Q: Metal ‘M’ forms a peroxide of the type MO2, Valency of the metal wrt oxygen is?
Doubt: ik generally it is +2 but if we take an example like sodium peroxide won’t we take the valency of the sodium to be +1 bc I have never seen Na have a charge +2, is it an exception case ?
Excuse me if I am missing a stupid point

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.peroxide has a valency of 2 because of the way the oxygen atoms are bonded in it, hence u will need 2 Na 1+ ions to bond with it and make it neutral
for the structure of peroxide: only 1 covalent bond is formed between the oxygen atoms and both atoms will have an empty space and accept 1 electron (ionic) each (hence 2 valency)
@stormycloud
isnt it like sodium and magnesium only
the others in group 1 form superoxides or just oxides
lower ones, yea down the group form superoxides as well
rather Na and Mg do NOT form superoxides
reason is in jd lee (kindaxD)
nono i said they form peroxides, the others form superoxides
i didnt know the ones below could form peroxides, i looked into it now
i did self study of s block before school started, ig i missed this
nice that you did this! if you wanna look up stuff for jee adv, jd lee is a good resource
Tysm, I asked this to sir today and he explained as well
So for valency of M won’t it be 1? Or am I missing something
ill wait for inorganic to start in school, and ill simultaneously solve jd lee then 👍
this case M has valency 2
since 1 ion of M is required to balance out the peroxide (which requires 2 electrons)
Wait why am I so stupid
Thankyou so much, I have been overthinking this for no reason 🧍🏽♀️
