All right, so metals are both malleable and ductile.
00:09
Malleable, of course, means bendable without breaking.
00:17
They will bend.
00:18
And metals are also ductile, meaning they can be drawn or formed into wires.
00:31
Again, without breaking.
00:33
They are not brittle.
00:36
And the question is, you know, why is that? how does the sea of electrons cause that? so let's think about a metal, and this metal has the positive nucleus, or the positive nuclei, i guess i should say, of each atom.
01:01
But the electrons do not belong to any one of these.
01:09
The electrons are all what are called delocalized, meaning they are just free to float around in here.
01:15
So that's why we kind of think of it like a sea of electrons.
01:18
The electrons are free.
01:20
To move, they're free to float.
01:22
We have delocalized electrons.
01:26
Now that is different from a covalent bond where specific electrons are shared and they're part of that bond or ionic compounds where we have ionic bonding where specific electrons are transferred from one atom to another to make ions.
01:40
This is different.
01:41
The electrons are just shared.
01:45
They are delocalized and so the bonds are also delocalized...
