Ans 5 Tq mam for your clear explanation about this concept & urs teaching superb for urs teaching any one Can under stand that type of teaching u gave mam thank u so much
Hy mam... Hope u r fine ... Could understand very well from ur lectures ...thanks a lot .. And the answer for the question is ... In the atomic no.15,the phosphorus element,has 5 electrons in its outermost shell and has its valency as 3
Carbon is the non metal but it can't loss or gain 4 electrons because this process requires much energy, but carbon is very small atom of the 14th group so it doesn't have that much energy to loss or gain 4 electrons so these carbon are special one which can't form ionic bonds (loss or gain electrons)like other atoms the carbon will form Covalent bond(sharing of electrons)
Your teaching is really helping me a lot mam And thank you for this wonderful teaching But the thing is carbon cannot loose electron or gain electron then how will be the valency of the carbon will be+4
Mam I have a doubt that in you have old outermost shell number will be valency number but from 3rd period u started marking two two outermost shell why😢
Ma'am what is a trick to remember the atomic number. Mam for our 10 STD it is enough to remember only 30elements. Mam what is weightage of this chapter according to board exam point of view. Mam plz send the sample questions paper.
Yours energy is excellent, superb teaching
Answer is 5 , the element with atomic number 15 (phosphorus) present in group No. 15 . Hence the valence electrons in this are 5
Ans 5
Tq mam for your clear explanation about this concept & urs teaching superb for urs teaching any one Can under stand that type of teaching u gave mam thank u so much
5 Valence electrons are present in atomic number 15 and my name is virupaksha
Understood mam👍👍
Your teaching is excellent mam
IAM big fan of ur channel
Keep Watching
All my concepts are cleared by your teaching skill. Thank you mam 🙏
Thank you..
Our only request is share with maximum students who are in need..
Sure mam
Mam when your are telling my heart felt sooo happy truly mam Thank you for explaining mam 😊
Marvelous
Perfect explanation mam thanks a lot
Keep watching
Mam, can you give me the link where you explain how to write electtonic configuration?

@@HomeSchoolChannel thank you
Ur teaching very nice madam
mam I like your teaching style and you are best teacher of chemistry ❤
Thank u mam it was very helpful
Super explanation mam
Thank-you mam.
Hy mam...
Hope u r fine ...
Could understand very well from ur lectures ...thanks a lot ..
And the answer for the question is ...
In the atomic no.15,the phosphorus element,has 5 electrons in its outermost shell and has its valency as 3
81st element is in group of 13 and its valence elctron is 1
How?
Mam 50th element is Tin and it's valency is +4and valence electrons are 4
I'm write mam
Mam your explanation is outstanding
5 valence electrons are there in Atomic number-15
5 valency of electron is present in phosphorus
Ha
5 valence elctrons are present in 15th whixh is phosphorus
5 valance electrons the element is phosphorous... May I correct mam
5 electron is present in atomic number 15

Thank you mam 🥰🤗
Thank you so much my l have doubts about valenecy you cleared for me you explained very well mam
Mam pls give me link of video how to write electronic configuration 1s1
........
Nice
Madam u have said 18 group valence electron is 8 but helium has only 2 electrons how it is?
Same here..
5 valence electrons thank you so much
Valence electrons of Nitrogen is 5,
Mam.......🤩
5 valance electrons are there in atomic number 15 From SVP school vishnu vardhan .B
Very nice teaching mam
Keep learning and share videos with your friends also 😊
Thank u mam for u r wondering class
Is it is necessary to remember all elements atomic number mam.............
Thank you mam....
Keep watching
@@HomeSchoolChannel ok mam sure I will watch your videos
Hi kavana
@@HomeSchoolChannel mam please give the link of electronic configuration
5 valence electrons are present in the element phosphorous having atomic number 15
5 valence electrons are present in the element with atomic number 15
5 is tha valance of Atomic number 15.....
Mam 5 valence electrons are present in group 15 elements
15th element is phosphorus and its valence electron is 5
Why valance electrons keep increases from left to right???
Due to atomic number is increased the Valance electrons is also increase
Mam can we write e.c as 2,6 like that instead of 25 2p
yes..you can...
Mam boron electronic configuration what is electron in last shell how we explain
Boron 5 ns2 ns2( np1 outer shell is 1
Mam In exam will they ask to draw any of the periodic table like draw mendeleev's periodic table or draw modern periodic table
No.. They won't ask like that
@@HomeSchoolChannel Ok mam
Thank you mam
Mam valency of 14th group element is -4 only, mam HOW IT IS +4, CARBON IS A NON METAL ONLY MAM
Carbon is the non metal but it can't loss or gain 4 electrons because this process requires much energy, but carbon is very small atom of the 14th group so it doesn't have that much energy to loss or gain 4 electrons so these carbon are special one which can't form ionic bonds (loss or gain electrons)like other atoms the carbon will form Covalent bond(sharing of electrons)
U once see carbon and it's compounds chp intro given by Nalini mam
U will understand better
Super mam thank you so much for doing this lesson so by that I really understand very well
Thank you..
Our only request is share with maximum students who are in need..
Refer your juniors..
@@HomeSchoolChannel yes mam
15 valance electron is there in the atomic number. -5.
Ma'am
Valency of grp 4 elements can either be +4 or -4 nah ma'am?cuz it is easy for thm to either give 4 or take 4 electrons
Neither they can completely lose nor gain electrons
They share elcetrons
But yes what u r asking is also correct as I also have the same doubt
Your teaching is really helping me a lot mam
And thank you for this wonderful teaching
But the thing is carbon cannot loose electron or gain electron then how will be the valency of the carbon will be+4
5 is the answer for the question for what u asked in last
5 valence electrons are present in atomic number 15
Helium having only 2 electron in her lost shell mam pls give answer
Yes .helium have only 2 electrons in its last shell
Mam defination of noble gases please...🙏🙏
Mam in 1st group hydrogen is a gas and all are solid then why it is in 1st group
It doesn't matter it's state we have to conclude only it's valence electron...
it's valence electron is 1 so it arranged in 1st group
Elements are arrange d in term s of atomic number
Mam do we need to memorize periodic table ?
Yes
Mam I have a doubt that in you have old outermost shell number will be valency number but from 3rd period u started marking two two outermost shell why😢
