what about the charge stability
is the electron also emitted -
very thanks
-
how does the proton gain mass and lose energy at the same time. If you take for example fission through electron capture the electron and positron annihilate releasing energy, and that energy must come from somewhere, could someone please explain?
-
It's K because it's Kalium in almost every language.
-
WHT dont you know!?!?!?
-
Your Programming stuff are way better:)
-
So how does this make Data's positronic brain work? (in concept obviously)
-
It is K because potassium is kalium in latin.
-
He I really like your chemistry class!
Here you change K in Ar and an electron.
40/19K -> 40/18Ar + e+
Ar argon is a noble gas. The positron e+ finds an electron e- easily to vanish both electrons.
After a while all K is vaporised as Ar and antimatter. Ha ha. Magic show!
Do not present theory that does not happen in real life. -
Great explanation!
-
I had to stop once you said a positron and electron colliding creates energy, which breaks the law of energy conservation i.e. energy cannot be created or destroyed. There are not 2 separate laws, one saying that you cannot create or destroy energy, and another saying you cannot create or destroy matter. Energy can be converted to matter, and matter can be converted to energy. They are still conserved, but they can be converted to one another. The law applies to both together, not each.
-
I've always heard it as "Matter and Energy can't be destroyed, only converted"
-
now there's proof of antimatter
-
lol
-
Dream Crusher :'(

You know they always told us that energy can NEVER be created nor distorted; but I always believed that, there IS way that energy can be destroyed. Otherwise the world wouldn't make sense.. I mean, what would happen if two energies, equal in power, were to hit each other? Both would cancel each other out, and would be nullified..
-
if you remove one positive charge from K to form Ar, wont u just be removing a proton?
because a positron has the same mass as an electron….a proton on the other hand is much heavier than an electron…
this still doesnt explain how u get a positron out from a normal element -
1:45 in german it is called "Kalium", which fits to the letter "K".
So the question is not why the beginning letter is "K", it is why in English it is called "Potassium". -
This is a hour long lecture in it's self. Basically Mass is the quantity of inertia possessed by an object or the proportion between force and acceleration referred to in Newton's Second Law of Motion. Matter is any substance which has mass and occupies space.
I hope that helps a bit. Take some time thinking about these things.
-
Einstein says, energy is equivalent to mass; k*m = E do you know where the distinction is btwn mass and matter?
-
Thanks Man, extremely helpful
-
(3)…. now, to be simple, electrons are just to small to affect something due to its mass (while the magnitude of the charge DOES affect much) BUT are NOT massless
I personally see that as some kind of segregation or discrimination against electrons but it's just being practical
hope I cleared a bit your doubt (and sorry if I confused you even more) [just wanted to help, I swear, but I'm just 15 ;w;] -
(2)… the nuclear force that binds the protons together gets weaker as the size of the nucleus increases, and
the repulsive electromagnetic force between the protons (all positively charged) grows as there are more protons -
(1) nope, the electrons have very little mass compared to a proton (actually 1/1836 [the 1836th part of the mass of a proton is roughly equal to the mass of an electron])
that difference is so significant that we could say the mass of an electron wont affect much at this point {because you would need an atom with 1836 protons (and hence 1836 electrons) to affect the atomic mass by just 1!} and that is just totally unrealistic because the nucleus would be 'extremely' unstable because: … -
But how come the positively charged electron's mass is equal to the mass of the proton? Shouldn't the mass on both sides be equal?
-
Positron LASER
-
No,,0. Actually means that it contains no protons or neutrons in it (since the definition of mass number : the number of protons+neutrons ))
-
When you write 0 for an electrons atomic mass, are you implying that electrons are a massless particle?
-
Oh sorry 🙂
-
potassium in Latin is kalium 🙂
-
It's potassium.
-
k is from kalium I think..
-
that -> arrow is like ????, you dont know what happens but later you have profit!
-
Please continue doing chemistry tutorials! I like them =)
-
@Misteryman94 Thanks

@teringikbengoed
Ar is argon – it's a noble gas
Au is latin aurum which means "shining dawn" – gold,
Ag is latin argentum which means "grey" or "shining" – silver -
yes sir here in belgium pottasium = kalium
-
Wait, so with a Positron Emission you can create a new element out of a random element only will it be the element with one proton less, but if that works for all matters, than one could turn a period III matter which is (most likely) harmless into a period II matter which unleashes fire-reactions when combined with water, and who knows what the Positron will add to the effect.
Is that really possible? -
and not suitable
-
are u gonna cover that to, because i have to tell pupils of 10 how it works (i am 16)
and your explanations are really good ( episode 1-5 are already usefull, the rest is mostly new) -
and btw from the verry basics episode 1-5
u comepletely skipt/ have forgotten about the basic/normal reactions -
it seems like everybody is Dutch wtf
How can this be???? I m dutch 2 -
its hard 2 be dutch lol
same problems 4 me -
If this where Dutch it would be epic, but now al the Dutch and English words spin through my head. Potassium is Kalium in Dutch. Ar is silver? Or is it Au, no that's gold!
-
Yes K is kalium in most non-english languages
