Question

why is the structure of copper stable

Answer 1

which structure?

Answer 2

LOL Copper FCC structure it has due to high atomic fraction its stable i think!!

Answer 3

copper is stable due to having a high boiling point so is a solid.

Answer 4

it is has a high bp because it is stable, not the other way around.

Answer 5

cause and effect

Answer 6

Copper has the configuration \([Ar]3d^{10}4s^1\). As you might notice it's a bit strange, right? You'd expect it to have: \([Ar]3d^{9}4s^2\) because the s-sub-shell should have been filled and it is 9 steps along the transition metals, hence \(3d^9\). However, it's more stable to have \([Ar]3d^{10}4s^1\) configuration. It is more stable, because 3d sub-shell is full, which is a far more stable arrangement than \(3d^9\). I think this is as much as you need to know for high -school level, however, if this is for an undergraduate study course, you also want to take into account exchange interaction whish is important in explaining this, but all this half shell and full shell effects are just a result of these quantum mechanics which is not covered in high school, and this idea becomes a bit more complex and less easy to explain.
