Since they had experiments that showed that when an electron moves to

energy(absorp photon).....therefore:

Yes, in order for an electron to move to a higher
energy state, it requires an input of energy.

Does electron acceleration cause Radiation Absorption?

An atomic shell has nothing to do with acceleration.

However absorption of a photon does cause an electron
to increase in energy.

Ok then an increase in energy is an increase in velocity (and not an
increase in mass) which is an acceleration?

No.

An increase in energy is not necessarily an increase in velocity.

In the case of a jump to a higher energy shell, it DEFINITELY
is not an increase in velocity.

Are you claiming photon absorption will not cause the electron to
increase in speed?


That's correct. An electron bound to an atom is not in
an orbit. A higher shell is not a higher velocity.

Assuming velocity has any meaning in an electron shell at all. IINM,
the average velocity of an electron bound to a shell would have to be
the same as the velocity of the atom... :-)

Unless, of course, one gets into weird areas such as solid-state physics
and metal electron conduction, which I'm less than familiar with,
from a QM level. To be sure, I doubt those are bound as such.

I presume when they say an electron has a velocity of millions of
meters per second in a copper atom but it's drift velocity is in mm
per sec..is un-related (the energy/voltage given to the copper will
not provide a velocity of millions of meter per second to the
electron)?

An electron in a conductor is not bound to a single atom. They
are in a random walk, moving at high speed in random directions.
Applying a voltage causes a bias in that random walk, so they
tend to drift in a certain direction as they bounce around.
