Metallic Bonds

The metallic bonds within metals consist of metal cations surrounded by a sea of electrons and so the outer electrons are delocalized and so they are not associated with any particular atom of the metal and so the delocalized electrons allow metals to be soft and able to shaped or malleable.

I’m going to write up here, the outer electrons are delocalized and now I’m going to write down here characteristics of metals, so because the outer electrons are delocalized metal can be malleable or easily shaped.

The following transcript is provided for your convenience.

Now the metal cations are not held tightly in one, so they can move relative to each other when they’re stuck. I’m going to write here, not held tightly and then in parenthesis I’m going to write metal cations, just to make sure that everyone is clear on what we’re talking about here. In addition to that, these metal cations can be drawn in fine wires, which mean they are ductile and so the cations are able to slide past each other with negative electrons in between and do not experience the repulsive forces.

The sea of electrons acts almost like lubricating oil between moving parts and a piece of machinery. Now the metal cations and various electrons are held tightly together, so I’m going to write MC for metal cations and VE for various electrons are held tightly together and because metal cations and various electrons are held tightly together, metal can have high melting points. Because metal cations and the various electrons are held tightly together mean they have high melting points, so that means the metal can have high melting points over a wide range.

Now the electric current is easily carried by the delocalized various electrons in the sea of electrons and so that makes metal as whole good electrical conductors. I’m going to write up here, electric current easily carried and then I’m going to write down here because metals are good electrical conductors. That’s a look at metallic bonds.
