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.

Yotube vids like this helped me study for the GAMSAT, and I’m 35. Even as the brain ‘ages’, products like this make learning easier. Brilliant.

then i m lucky to know youtube coz i go to school
i really like the subject. . . . . . . . . . i have already watched 19 vids of cassiopeiaproject

Great video. Great!

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.

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.
[Translate]
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.
[Translate]
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.

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.
