Aluminium valency is +3, since it can donate 3 electrons to achieve octet state( stability) and the charge will become positive(cation) since the loss of electrons ( negatively charged particles) will cause the atom to have an imbalance and become positively charged.

Is there any next rule like Duplet, Octet coz..the logic of Duplet and Octet means IF the Electrons of an atom has come completed the capacity of a particular shell(last shell) THEN the atom is stable. So my question is .. Is there any next conderation like Duplet rule was of first shell, Octet rule was of second shell...what's further... Anyone helpful... please solve my doubt...🙂pre

Hello Madam, I am a viewer of your lecture from Abu Dhabi and this give me a fantastic feeling to write that you have got fantastic nature, wonderful knowledge and magnificent methodology of teaching. The core thing is that you make the thing simple rather showing showing the highest degree of complexity during teaching. Once again, I am highly impressed of your soft nature and way of teaching...... GOD Keep you blessed always.
For atomic mass , if atomic no. is even then multiply 2 with atomic no. to get atomic mass . Or if atomic no. is odd then multiply 2 with atomic no. and add 1 to get atomic mass .There are 4 exceptions nitrogen ,argon , hydrogen and beryllium do not follow this rule ..

2,8,18 was a concept ..till now i dont remember why it was taught ...but for configurations...use 2,8,8,8,.... Electrons may be less than 8 but never exceed 8 Eg. For sodium 2,8,1 Only for noble gases ..shells are always filled .. Eg neon 2,8,8 Hope it helps
Ma'am you taught soo well but the slide the screen wasn't clear you weren't rubbing and were writing a soo lot on that everything was great but this was something which every student would have felt
ALUMINIUM = IN FIRST SHELL MAX.2 ELECTRONS CAN FULFILL . AND IN LÀST SHELL 8 ELECTRONS CAN FULFILL SO 2 , 8 , 3 so valency will be positive 3......is it right

I don't know if anyone got this, look at the top right corner of the slide 3:00 , that is the slide of Don't memorize
Ye bhai
OMG 😳
The slide is from "Don't memorize" channel
Yes
where is that vid by them?
its the second slide there is the sign of the channelon the top right corner
Atleast we come to know that Vedantu watches videos of my favourite educational TH-cam channel
@Best-Ever Tech Live no he isnt

actually there is no topic which is hard in it's real sense ,these just are basics which are not clear and make the topic critical and too typical and yaa anubha mam is just wow💯💯👍👍
Exactly
No , there were many camera cut
Homework Answer;
1)NaHCO3→ SODIUM HYDROGEN CARBONATE
2)CO→ CARBON MONOXIDE
3)Limestone→ CALCIUM CARBONATE→CaCO3
4)Caustic Soda→ SODIUM HYDROXIDE→NaOH
NaHCO3 means baking soda
My answers are also same...
Anubha Mama's energy is out of my brain ...😂👍Really appreciate her teaching ..
She's energetic! 😂💜

Aluminium valency is +3, since it can donate 3 electrons to achieve octet state( stability) and the charge will become positive(cation) since the loss of electrons ( negatively charged particles) will cause the atom to have an imbalance and become positively charged.

Valency=➕3
Trivalent cation
Legends are those who are watching it before exams 🤣
Yes bro
Tomorrow's my exam lmao
Yes
🤏😎
Write bro🤟
NaHCO3-----Sodium bicarbonate
CO-----Carbon monoxide
Limestone------Calcium carbonate
Caustic soda------Potassium bicarbonate
Mam how could we know the valency of a compound like carbonate while making calcium carbonate
Yeah! I also watched this whole video for that but wasted my 38 min.
Yaa u are 100% correct I also looked for it
Please ma'am clear our concept
We have to learn it
valency of carbonate is 3 and the formula of calcium carbonate is CaCo3
Home work answer --
1:-) NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen + Oxygen + Oxygen.
2:-) CO = Carbon + Oxygen.
3:-) LIMESTONE = CaCO3 or Calcium+ Oxygen + Oxygen + Oxygen.
4:-) CAUSTIC SODA = NaOH or Sodium + Oxygen + Hydrogen .
This session cleared all my doubts.
Thank a lot mam.🙏🙏🙏🙏😊😃

How to find compund formula with variable valencies,
Like copper whose valency is 1,2
Mercury-1,2 etc
So when forming compund which valencies we have to criss-cross
Nitrogen( electric configuration) is (2,5) and it's valency is (-3)
Yesss
The octet rule state that in the outermost shell of the atom contains maximum of 8 electron👍🏻
Right!
Tq
NaHCO3 - sodium bicarbonate
CO- carbon monoxide
Limestone - calcium carbonate (CaCO3)
Caustic soda - sodium hydroxide ( NaOH)

When the atom gets stability of 8 electrons in the the outer most shell it is said to have an octet
chal chal tere baap ko mat sikha
Is there any next rule like Duplet, Octet coz..the logic of Duplet and Octet means IF the Electrons of an atom has come completed the capacity of a particular shell(last shell) THEN the atom is stable. So my question is .. Is there any next conderation like Duplet rule was of first shell, Octet rule was of second shell...what's further...

For next all shells there will be octet rule only for ex:2,8,8,8,8,8

Octet rule completes when the last shell contains 8 electrons

If valency of flourine is _1 then what will be the oxidation state of flourine?
@Adroit Absart I know but they are telling that both oxidation and valency are same,how can it's possible broo
Valency and oxidation states are different.
Flourine can form 1 bond, so it's valency is 1.
While oxidation state of flourine is -1

But in one video of ur class u told me valency of fluorine is _1 so I asked that
Nice , actually I have already Read it on this lock down condition at my home for extra knowledge.
1 orbit = 2
2 orbit = 8
3 orbit =?
if it has 4th orbit =?
3 =18
4=32

Happy teachers day anubha ma'am ❤️
Octet rule states that last shell must contains 8 electron for stability .

very nice explanation
I really like
Valency of aluminium is 3 🙂🙂
Valency of aluminium is +3 as according to law its2,8,3 and it will lose 3 electron so +3 in order to acheive octate rule or to acheive stability
Can anyone see the logo of "Don't memorise" channel in the top of the board

Ma'am the third shell should have 18 electrons know ma'am ....then why only 8 are considered..why?
Friends anyone pls answer
Brother if u want the answer of ur question u have to learn about subshells and its properties
Ok thank u for ur reply
2,8,18 was a concept ..till now i dont remember why it was taught ...but for configurations...use 2,8,8,8,....
Electrons may be less than 8 but never exceed 8
Eg. For sodium 2,8,1
Only for noble gases ..shells are always filled ..
Eg neon 2,8,8
Hope it helps
😊 thanks
You can understand it in higher classes
Mam i have a doubt to attain stability atom will lose or gain electrons then what about protons because it is said no.of protons=no.of electrons
Nice explanation 👌 it is very useful 👍 thanks ma'am 👍
