Chemistry: What is a metal? / Metallic Bonds

⬣⬣⬣
Metallic bonds are one of the 3 main types of intermolecular forces, along with ionic bonds and covalent bonds. Metals are shiny, malleable, ductile, and good conductors of heat and electricity. Is there a reason, chemically, for these characteristics of metal?

In this video we explain the connection between the nature of metallic bonds and these typical features.

*Metals are shiny, malleable, ductile...but why*?
Our latest chemistry video explains why metals are so...metallic!

This feels like an advertisment for metal

I love the illustrations. They make the concepts much easier. I found the hammering of metal-bit especially helpful. Thank you for your wonderful video!

[VidyaSagar-ztiy]

We need more
Videos like this, tq for this clear and simple explanation

[Liam-ebzb]

I was looking for death metal music. Wrong video.

[yazushi]

Very useful
I was having a trouble understanding why are they malleable and ductile but now it's so easy
Thank you so much !!!! Great job

[Prasad-qx]

Thank you very much. This more interesting. especially your animation was exactly synchronised for better understanding.

[edgeeffect]

Never heard of metallic bonds before but, back when I learned chemistry, they didn't mention hydrogen bonds of Van der Waals force either....
(After actually watching video)... thanks for that... conduction of electricity and the nature of semiconductors makes A LOT more sense now.

[schoolwithapril]

Thank you ! I needed a quick metals properties overview for my kiddo. This did the trick!

[alexandrechaillet]

great and easy to understand, a lot of questions that I had for a long time are now clear !!!

[DCSMdYusufAzam]

Such an easy and apparent explanation.
Really like it!!

[markcarey]

Excellent, feels like I learnt more from this than a textbook at school. At least, I understand it.

[royalroyal]

Your vids are SRSLY helpful

Good job you helped a lot

You made my day, I had a quiz the next day

You made it easier for me

Thnx

[shaikhzoya]

Good video but One thing I would like to point out
Gold is the most ductile element not platinum!

[declandorsey]

Very helpful. Thank you so much. I hope all is well.

[seekingsnowflakes]

This video helped me understand metallic bonds much better :-), plus I learned some interesting metal facts :).

This woman has a great voice for science narration!

they say nonmetals are rough but I'm sure a lot of surfaces are as smooth as metal and yet they appear white rather than shiny. An opaque quite smooth surface will have a small amount of reflection but not as much as a mirror or metal has and this is because it's non-metals are translucent. Non-Metal electrons aren't as easily excited therefore the light waves pass below the surface (not having enough energy to excite the electrons the light passes in but nowhere as far as it passes into glass but glass has the same problem of not being able to absorb or reflect light, (atoms are mostly empty space)). The light goes below the surface to a depth greater than the wavelength and so the light that gets re-emitted is out of phase. Enough of it comes out for us to see but its much less powefull. On a metal since the light leaves immediately from the surface even though it radiates in all directions equally from every point interestingly enough that's already how waves behave as they travel through empty space (as if each point in space is re-emitting the same light in all directions). It's as if the light is spreading out in all directions equally. The fact that it's in phase is what creates the wave front. So when it hits a metalic surface it's as if the light simply passed through a window and it's doing simply what it was doing before but the wavefront is traveling in a different direction. However at a microscopic level the photons aren't just bouncing off the metal like a ball would. When the atoms absorb the light they re-emit that light in all directions creating many tiny wavefronts however they all do it at the same time from the same flat surface and the combination of all these tiny wavefronts recreates the original wavefront. The ones that were closer emitted the light sooner and so their wave-fronts are larger than the ones further away from the source the combination of the wavefronts creates a reconstructed wavefront similar to the one that hit the surface.

You are amazing. I wasn't even hoping to get it explained so well in such a short time frame. Thank you so much. (;
