the outer is the source not theinner just trust me. factor that in for everything and it all makes sense. think about it. think the universe like a hologram a human would look out and be blinded by the outer wall and the sun would help light things around us my girl is deaf and if i stand in front of the sun shhe cant see my lips so think the original light source as the darkness of space we need stars to see around us like a hologram we are blinded by the spotlight that created us
eventhough, the border between physics and chemistry is a vital part of physics, as well as chemistry, there is a huge lack of information about that topic avaliable.
One type of atome pere element? Moron, there are istopes. You can't visualize a proton like that, no one has ever looked inside a single proton as you show it there. Proton and electron don't form up hydrogen when you move the electron inside to proton as shown in the video. Why do you show a p-orbital when hydrogen is in 1s state. Showing a single electron as hundreds of dots is wrong, thats a snapshot of the locations the electron can be at. There are so much misconceptions in your videos.
no , a classic tire is literally 1 single molecule ..with groups that can repeat ...
the same way DNA is a single molecule .....if u could stretch dna it would have like 3 meters ....but its tighly spiraled inside the nucleus of the cell.
but a tire is just bigger .. the exact name is cross-linked poly-isoprene
the formula is something like (CH3)(CH2)CC(CH2)(CH3) + S8 ...and u get continous intertwined groups ...
repeat that 55 trillion times and u get a rubber tire
This video did not discuss van der Waals interactions, forces or bonds. Also, this video did not discuss metallic bonding. Of the 5 major bonds, this video only talks about 3 of those bonds -- namely, covalent, ionic and hydrogen bonding, this video does not mention anything about van der Waals or metallic bonds.
More than 5 chemical bonds exist in nature. Lets not forget about: aromatic bonds, bent bonds, 3c-2e and 3c-4e bonds just to mention a few.
this is the most informative description i have seen so far on the subject, the graphics have truly enhanced my understanding also, and let not anybody underestimate the value of the comments made so far. do note the references to quantum physics in the 'electron cloud' graphic representation and the comment about modern physics. thankyou, cassiopeia, for the quality educational media.
There is one problem in this otherwise wonderful video. Ionic bonds are weaker than covalent bonds. The reason sugar melts at a lower temperature than salt is that salt's ionic bonds act to hold the entire solid together. Sugar's covalent bonds only act within the sugar molecule. The dipole-dipole forces and London dispersion (sometimes called Van der Waal's) forces between sugar molecules are weaker than ionic bonds. Look at diamond for an example of how strong covalent bonds are.
We agree with you in principle. Chemical bonds of "different types" actually form a range of strengths and there is no really clear delineation between the types. In our effort to simplify the concepts we may have painted too sharp a difference. Comparing Ionic and Covalent bonds in general terms can fall apart when you start to look at specifics.
However, it takes 787 kilojoules per mole to break the Na-Cl bond in sodium chloride while a carbon-carbon covalent bond requires something on the order of 154 kilojoules per mole. As a rule of thumb, the more a bond is like an electrostatic attraction between unlike charges, the more energy it takes to disrupt. Thus the assertion that ionic bonds are stronger than covalent.
Is it 99% sure that electrons are flying around the atom. I've heared that it was prowed to be false, but is still used for demonstration and easier explanation.
The modern view is that electrons trapped in atoms take the form of an electron shell. These shells or orbitals can have a variety of shapes depending on their quantum numbers. The older picture of electrons in atoms traveling in circular orbits around the nucleus is false.
Thanks for your comments. To answer your question, there is no short-range repulsive force between stars or other massive bodies, so if they are on a collision course they will crash into one another.
Thank you CP! I've always wondered if really big things behaved like really small things. Whenever I see a representation of an atom with orbiting electrons, it looks very much like a star with planets. However, I'm starting to guess that the standard illustrations of atoms do not accurately depict what they really look like, and that I am incorrectly drawing parallels where they do not exist.
Fantastic video. I hope you go into teaching. Have you heard about teachertube? It's like YouTube, except that all of the videos are educational and intended as a resource for instructors. I also have a rather ignornat question, but one I've always wondered: do the interactions described in this video parallel interactions between solar systems? When/if two stars drift near one another, do they form "bond distances" or do they crash into each other?

is it possible to make one molecule the size of a grape? or even larger?
would that create a black hole?
xXDominoXx 2 years ago
the tire on your car is one huge singular molecule
and its not a black hole
a black hole is simple alot of mass in a single point in space ..
all black holes have the same size but their event horizon differs according to their strenght.
it has nothing to do with molecules.

@cassiopeiaproject 787 kilojoules per mole m(NaCl) = 58.443 g/mol, and the total for ethylene is ap. 1MJ/mole M(C2H4) = 28.05 g/mol
so the total energy per kg of covalent bonds can be higher............

Disrupting the bonds in something like table salt takes a lot of energy. Disrupting the bonds in a sugar molecule will take considerably less energy.
