Trick to Calculate Atomic Mass of first 20 Elements

#jee2024 #atpstar #neet2024

[atharvajoshi]

Once a wise man said :
"Woh chemistry hee kya, jisme exception naa ho"

[focusfam]

Hydrogen=1
Beryllium=9
Nitrogen= 14
Argon= 40

[sharmaschannel]

Hydrogen=1
Beryllium=9
Nitrogen=14
Argon=40
Chlorine=35.5

[SurajGuptaMEA]

What a simple and charming way of teaching!

[prachi_theofficial]

Hydrogen - 1
Berrylium - 9
Nitrogen - 14
Argon - 40
Chlorine - 35.5

[ifjkwgt]

Also chlorine is the exception... Z=17(odd)...so 2z+1=35 but the value is 35.5 which we used in numerical.. btw thank you mam for this trick ❤

[sujalrade]

Thank you mam exactly it was a super trick

[sharmisthachowdhury]

Thanks a lot ma'am...it helped a lot ..And I think chlorine is also one of the exception -(35.5).

[bhavyanshdhakhad]

Thank you mam, brilliant explanation, found it really helpful.God bless you...

[Technaton_English]

Nehi ise aise yaad rakho Lithium se lekar 3 elemts tak 2Z + 1 phir 3n elements taak 2Z + 0 uske baad se yeh rule dhaang se bina ruke follow hoga aur argon ko +4 yaad rakho

[unknowneplayer]

Just remember H, he, C, N, O, Ca, Mg, Si, S, Ne.. Square thier atomic no. Reameaning are square and +1

[irshadkhan-ekly]

This helps more than my actual teacher 😃

[shyamduttbhatt]

Atomic mass = no. of proton + no. of neutron
Atomic no.= no. Of proton =no. Of electron
NO. . Of neutron = mass no.- atomic no.

[try_new]

Acception=chemistry mam chlorine laughing 😝😝😝😝😝

[lsvvdsm]

Hydrogen 1
Berilium 9
Nitrogen 14
Argon 40

[MdMerajmaths]

There is also 1 exception i.e, chlorine (cl).

[Aryan-ikgh]

Me who doesn't even know atomic numbers of elements 🥲.

[S-K]

This is the point of real life challenge, paying attention on Beautiful Teacher or else Beauty of Education

[Sanjaychaudharyv]

This teacher change my life ... How to learn atomic mass ❤

[kjbozeh]

Many students are asking about CHLORINE so here is the answer....

Bcs Isotopes of chlorine Cl35 & Cl36 are kind of same & equally distributed so bcs of similarities scientist consider these Isotopes as one Chlorine so simply they calculated the average mass which is 35.5 & it's now the mass of Chlorine..

Hope u understand & if I made any mistake apologize for it🙏🙏🙏🙏..
