Hey pplz, electrons in metals are accelerating right, and accelerating electrons give off X-rays. Does that mean metals give off X-rays??????

 

[Suvat]

Electrons in metals are standing waves, thus even though they are accelerating, they do not emit energy, otherwise all the electrons will spiral into the nuclei and matter as we know it will cease to exist

.....interesting...nice one abood

 

[Xayma]

Remember that not all acceleration results in an increase in magnitude of velocity, as velocity is a vector quantity a change in direction is acceleration.

Conduction electrons are free electrons that are not bound to the nucleus. Only bound electrons satisfy the condition of standing waves.
In any case if these electrons were standing waves they would never give off energy. They would be superconductors!
X-rays generated are not powerful enough to leave the surface.
Instead they turn to heat....hence heat in conducting wires

Lek HUUUUUUUUUMMMMMMZZZZZEEEEEEEHHHHH!!!!


No one said that X-rays should be the subject of the matter.
Accelerating electrons emit all sorts of EMR, From RAdio to Light to maybe even GAMMA.

I think conducting metals produce Infra red heat directly instead of converting x-rays to heat.
Makes more sense, no??

MY FIRST POST!!!!!!!!!!!!!!!!!!!

uhm ... i haf to say taht i disagree... in metallic bonding, the conducting band/lowest unoccupied moleular orbital/anitbonding orbital and valency band/anitbonding pair/highest occupied molecular orbital overlaps.... they are in a standing wave/orbital hence do not lose energy due to constant acceleration...

also tis dangerous to think electrons physically travel to one pt or an other... cuz on an atomic scale, they exhibit wave property,they trevel in standin wave form...
