Difference Between Bound And Free Electrons

What is the difference between bound and free electrons?

Ans:

SN	Bound Electrons	Free Electrons
1.	These electrons are present in the inner orbits of the atom.	Free electrons are found in the outermost orbit of the atom.
2.	i.e. Bound electrons revolve in the orbits closer to the nucleus.	i.e. These electrons revolve in orbits far away from the nucleus.
3.	The nuclear attention on these electrons is maximum.	The nuclear attention on these electrons is minimum.
4.	Bound electrons can not move freely in the side of the crystal.	Free electrons keep on moving freely from atom to atom as well as move randomly in blank spaces among the atoms.
5.	The properties of all bound electrons are not alike.	The property of all free electrons is alike irrespective of the material from which these are obtained.
6.	Their energy is minimum.	Free electrons energy is maximum.
