Wonderful and a clear explanation. It made me to understand everything clearly. Thanking u for this uploadence of video. The language that used in this video made a clearance of the topic.
The elements that react very vigorously with water and air are immersed in mineral oil....But mg is not so reactive so it doesn’t react with water and oxygen in air so it’s not put in mineral oil...
plz make a vid for transition elements i need in my exam for tmw plz ps. i really admire your work and i love ur vids i showed the to my teacher he gave me plus 5 thanks *TRANSITION ELEMENTS* QUICK PLZZZZ
0:48 Why have you said that beryllium is an exception in losing two electrons? The electronic configuration of beryllium is 2,2 and it will also lose 2 electrons to achieve a stable state. Please answer!
1:26 what do you mean by "shiny and silver', I know that silver is an element, and if I'm not wrong, are trying to say "Shiny and like Silver". Please, do let me know. Thank you!
In finely divided forms Magnesium is easily ignited. It burns with an intense white flame. It can also cause skin irritation. And so you must not touch it with your hands.
this is because, nuclear charge increases AS WELL AS number of shielding electrons therefore, the dominant factor is the more energy levels and so the electrons are further away from the nucleus therefore it is easier for electrons to come off. so we can say Na is more reactive than Li since it is easier to remove electrons.
Each period adds a new layer of electrons, so the last 2 electrons become further and further away from the nucleus which makes them easier to separate from the nucleus so they react more down the group. Reaction depends on exchange of electrons. Easier to gain or lose an electron? Now reactive.
This is because the electrostatic attraction between the nucleus and the outermost electrons " valence electrons" as you go down the group weakens so they can " fall" off easily so making the reaction faster
Is it too much to ask to explain why the elements in group 2 are more dense, reactive, softer going down the group? Think it would be easier to understand the periodic table rather than just memories the facts, also would be more useful in life....I think so anyways.

Glad you liked it! 🙂
Thank you, this helped me with studying for my periodic table test.
Glad it helped! What did you get?
FuseSchool - Global Education can’t really remember, this comment was from ages ago that I kind of forgot I commented it, but I think I got a 6+ ❤️
Nice 🙌🎉
@@jessgrace2191 hobi!!
@@Divina1024 ARMY HERE
excellent teaching!!!!!!!!!!
Thank you! 😃
i love it can u make lesons in maths and english
it helped me get a 9 on my GCSE
Nice one! We've got many maths videos, please check our playlist: ua-cam.com/play/PLW0gavSzhMlTKBNbHH5u1SNnsrOaacKLu.html
Would u mind explaining some entities like
Why magnesium is not stored in oil
Why the melting/boiling point decrease
Please
Yes, please

Effective video 🎊
Glad you think so!

How did your exam go
It's been 5 years how did you do in that exam?
Good like really good
Hold up
What was the exam again
@@AhmedMohammed-sm5yw lol
This videos of properties had helped me a lot
i got 76.5 in chemistry out of 80
Amazing! Wee done 🙌
Thx
❤️ from INDIA
❤️
Whose teacher sent him to watch this video during Science online class
Amazing Thank you😊
Why is magnesium not stored in oil when it is highly reactive with oxygen in the air?
Who was sent here by their chemistry teacher?
You helped so much, thanks 😘
No worries 😊 Happy to help!
Good going
Thank you very much...❤️
Always welcome 😊
Explained very nicely
Thanks a lot!
Thank you I've recently started to seek knowledge. And this is knowledge that I need.
The Isaac Francisco Channel me too , it’s very helpful
The Isaac Francisco Channel what are you going to be when you grow up ? Im going to be a cop
Edgar Ocasio happy
Great
Thanks this really helped me with my homework :)
Why is calcium softer while it’s density is higher than magnesium
0:48 Why have you said that beryllium is an exception in losing two electrons? The electronic configuration of beryllium is 2,2 and it will also lose 2 electrons to achieve a stable state. Please answer!
@Dynamic Because the person in the video said it
top notch productions
It's was perfect, you teach us very well
Thank you! 💜
Thank u so much from India🇮🇳
Most welcome 💜
Love this♥️
Thanku mam
No problem!
hi good job
Agrreeedd
good job
1:26 what do you mean by "shiny and silver', I know that silver is an element, and if I'm not wrong, are trying to say "Shiny and like Silver". Please, do let me know.
Thank you!
Sorry about the confusion! What we meant was that it has grey-white colour or appearance like that of silver.
Love it...😘
Nice explanation very thorough and nice thx!
Thank you all!
👍
1:43 can we use our hands to hold the Magnesium strip?

@@fuseschool thank you for your explanation
Why does the Mg has lower melting and boiling point than Be and also other elements of the group??
Becuase OF COVID-19
?????why magnesium is not stored under the oil
pls note the error in equations at 5:03 they are incorrectly written ,but is correct at 2:05 and 3:02
+KP KP13 thank you for spotting this. I have annotated over the incorrect equations.
Ok
calcium
also transition metals and lanthanides and actinides!
made group 3 to 6 quickly!
Hi
Hi?
why does the reactivity increase as you go down the graph
this is because, nuclear charge increases AS WELL AS number of shielding electrons therefore, the dominant factor is the more energy levels and so the electrons are further away from the nucleus therefore it is easier for electrons to come off. so we can say Na is more reactive than Li since it is easier to remove electrons.
Each period adds a new layer of electrons, so the last 2 electrons become further and further away from the nucleus which makes them easier to separate from the nucleus so they react more down the group. Reaction depends on exchange of electrons. Easier to gain or lose an electron? Now reactive.

05:08 you put the solutions the wrong way
Calcium
Is it too much to ask to explain why the elements in group 2 are more dense, reactive, softer going down the group? Think it would be easier to understand the periodic table rather than just memories the facts, also would be more useful in life....I think so anyways.
Thank you! Noted!
