☺✌Hiii here is your answer..☺✌
free electron in metals.........
When electricity flows, the electrons are considered "free" only because there are more electrons than there should be, and because the transition metals, such as iron, copper, lead, zinc, aluminum, gold etc. are willing to transiently accept and give upelectrons from the d-orbitals of their valence shell.
work function........
work function
the minimum quantity of energy which is required to remove an electron to infinity from the surface of a given solid, usually a metal.
hope it's helpful for you
