Why didn’t I find this last week, in my chem exam I had to give the s,p,d
number of chlorine.
Now I know why electron shells come in the order of 2,8,8. But according to
the Pauli exclusion principle, no two elements could have the same electron
shell. If we take a helium atom with 2 electrons in its first and only
shell, we would say that they have the 2 different energy thing states.
Having 2 helium atoms will mean that there are 2 electrons occupying both
states. I’m only 15 and doing GCSE but I’m ahead of my class. So forgive me
if I didn’t fully understand.
In reply to cadkls, you can have 18 electrons in the 3rd shell not just 8.
[This was demonstrated in the video], which I hasten to add was excellent.
can you do a video about the crystal structures and lattice energy etc…?
Thank you so much for this, it really helped clarify all the problems I had
had with intro chem and that followed me into my studies of physics. This
is great.
i’m a 3rd year physics student at university, and i have to say this is the
best explanation of electron shells I’ve ever heard
great videos. better than my prof.at Cal!
Not this specific video. But I have a complete A level revision playlist
which serves that purpose, with a full range of videos covering all the A
level material.
Outstanding videos! you always seem to anticipate and answer the questions
that come up as I watch them! 🙂
He’s fantastic. However, if you think this is great as a third year physics
student, your instructions and texts given to you must be average at best
This is good but it doesnt explain how to find/determine ml or ms. I hope
there is extra credit on this test im going to fail 🙁
you forgot to put the negative sign in the RHS of the schrodinger equation.
It should be Epsi = -h*2/2m d*2psi/dx*2
i love you
great video. Really helped.
Thank you so much for this video and others you did! 🙂
Youtube is my educational learning space, not uni -.-
Yes you are right. I probably conflated too much here. I was expressing the
energy as a negative term (Binding Energy). But I have inserted an
annotation to explain. Thanks.
Nice vid! This is an invitation to see an artist theory on the physics of
light and time! This theory is based on two postulates 1. Is that the
quantum wave particle function Ψ represents the forward passage of time ∆E
∆t ≥ h/2π itself 2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π
that is formed by the w- function is the same uncertainty we have with any
future event that we can interact with turning the possible into the
actual!
best lecturer, period! ^^
Do we know whether electrons will go to shell with m=-1, m=0 or m=1 first?
Or is it random process? If it is, do we know probability distribution?
fantastic for further detail into my as level course!
is this targeted to people who are going to, A level physic from GCSE ?
umm i don’t think glass is a good example, glass is a lot lighter and
taller than curl stone, making it act exactly how you described, but a
curling stone does not act like glass, because its HEAVY and short in
height. I think that curl comes from the simple rotation itself.
have anyone tried the same thing with any other object that is similar
shape and weight? i think any object that is similar shape and weight will
act like that.
that’s also why curling stone does not touch the ground near edges, but
from middle. glass is just completely different thing and acts completely
differently.
Btw, why don’t you partner with youtube/google or one of the youtube
partner programs? you’d get all the “sponsoring” you ever need. your
current video views can easily earn you like 20000 usd a month :)
4:16 is actually false, the friction is not proportionnal to the surface
area.
6:56 FOX hahahhaha
I definitely thought the Canadian professor would be Pierre Baudin from the
University of Alberta. During one of my phys.ed biomechanics classes he was
talking about the research he did with Kevin Martin (Canadian Curler) at
the Saville Center in preparation for the Vancouver Olympics.
As a sport it is the most boring of the olympics, as a science it is pretty
interesting.
Science is amazing!
Why would anyone care about religion when we have stunning facts?
the curl is mostly caused by the sweepers who slightly melt the ice in the
desired direction causing a less friction path that the stone follows
We know the Olympics are long over, but, I for one, have never understood
the sport of curling. Check out this video to see all the physics involved
in this event. #physics #science

And people say curling is boring.
milwaukee wisconsin!
yeahhhh
hey im not sure if this makes a difference, but here i go.
around 2:36, you pushed the glass and spun it, hoping it would go in the
direction of the spin. It did not. it went the opposite direction.
I noticed, that when you pushed the glass, your elbow was a few inches in
the direction that the glass slid to. Instead of guiding the stone or elbow
with the hand, could the reason be that the glass slid in the opposite
direction be that your elbow was causing a “misalignment”.
im prolly jumping the gun, or over thinking it. im just saying it was an
observation haha.
I love how the people who invented the sport most likely didn’t understand
a fraction of these explanations of the strategies they developed just by
playing the game.
We swedes didn’t win the curlingmedal this OS but just you wait. Next time,
Canada! Next time… (or US or other countries 😛 )
LOL DAT FALL DOE!!!
who the fuck cares, its a gay ass sport that shouldnt even be considered a
sport or be in the olympics..
3:05 “Science? RUN!”
lmfao 2:40 haha
i have no idea if this is correct or not. but i think its simply a matter
of the amount of friction.
think of an object moving up and clockwise, the left side is speeding up,
the right side is slowing down.
and as we know all action has equal and opposite reaction, so the
acceleration of the spot to the left would be accelerating the object as
whole to the right.
friction would cause the object to swerve to the left, but as there is less
friction involved, the effect of the rotation itself would be stronger.
am i wrong in my thinking?
the same thing happens with footballers when they impart spin. look at the
roberto carlos free kick of 1997.
These clips are really cool and interesting.
I just get really weirded out by the bible verses in the end of these clips.
Superstition still rules humanity, its so weird.
Har länge undrat över detta :)
Don’t get me wrong, I throughly enjoy Destin’s videos, but whats with all
these youtube channels hyping their Patreon/Subbable things these days? Has
the youtube content creator business fell flat or something? No more google
adsense money in relation to channel growth? I’m just curious if its
because youtube alone isn’t making them enough of a return to support the
channels, or if its an attempt to honestly take the channels even farther
with more capital input. I’m not criticizing them one bit for all the time
and effort people like Destin have put into making their channels what they
are, I’m just concerned if this is a symptom of a much larger problem
across youtube for decent sized channels. I’d appreciate anyone’s insight
on this. Cheers, -aphex
MAYBE IT’S THE THING ON TOP??
