I have what may seem to be a simple question. When an element loses (or gains) an electron, where do they go (or come from)? Are there free electrons just hanging around that are available if needed?

[Priyanka-hqre]

I didn't understand anything. I am soooo damn confused now. Thank you.

[PunamKumari-isro]

9:08 when this is electrically neutral then why does it gain two extra electrons

[rohansachdeva]

Gud evening Mam
Mam why Carbonate have 2 negative charge
Since it's total no. Of electrons are 22. So, when we distribute them into magic numbers we get
2, 8, 8, 4
And since the carbonate must loss those 4 electrons and become a positively charged ion.
Why ❓
Plzzz reply me tomorrow is my exam🙏

[tosifahmad]

Mam can you explain stability of polyatomic anion..

[chemeeeasytri]

At time 7.30 the radical sulphite is explained, at the same time it's name is mentioned as sulphide.
Sulphite and sulphide radicals are two different radicals.
Please see to it.
Nice audible voice .

[adhyatmikgyan]

mam plz tell me that why there would be 2- charge and nothing else

[fntfragger]

Mam how is it decided whether electron would be gain or lose or how many electrons are gain or lose when polyatomic ions

[kidsworld]

Please explain clearly I didn't understand anything but I confused a lot please give clear explanation and post this video again THANK YOU...😔😔

[JatinSharma-ztuw]

Mam atomic no.s of oxygen & hydrogen are 8&1 resp. So there are a total of 9 protons not 7 as you are saying. So plz correct it or justify?

[harshgupta]

Al2(SO4)3 - Aluminium sulphate ka Bataiye kaise hoga mam plzz reply

[rudraharithra]

I have a doubt. Please clear it mam. How can we say the electrons are filled in the shell. I know that K shell occupies 2electrons, L shell occupies 8electrons, M shell occupies 18 electrons and N shell occupies 32 electrons and S-2, P-6, d-10, f-15. You are saying in sulphite Ion 26 electrons had filled the shell?

[YT-dybr]

From where hydroxide ion got one electron?

[fntfragger]

Mam I have a question is it necessary that whatever are the two elements the gain of electron would be 2 only in polyatomic

[anirbanghosh]

Areee. 2 e. 1 e extra Aya kaha se yeh to bol deti didi. Mujhe Jitna Malum tha ab vo bhi Appki daya se bhul gaya. Thank you didi.

[meenakshipathak]

How do S and O3 atoms make bound to form SO3 ion

[dilippurohit]

As a teacher I explained clearly. thank you Madam.

[amanthapa]

Also tell how charge calculated..in this video charge already mentioned

[videobhai]

Uper sulphide likha hai aur niche sulphite sahi se dekho 8:08 par video ko rok kar

[dilippurohit]

Sorry as a teacher i understood clearly. Thank you madam.
