Rutherford's atomic theory

core

a. All the positive charge and most of the atomic masses gathered at a point in the middle of the atom, called the atomic nucleus

b. Atomic nucleus surrounded by electrons at a relatively far distance

c. Atom is electrically neutral because the charge on the nucleus (positive) equal to the charge of electrons that surround it.

weakness

- Can not explain the stability of the atom

- Can not explain the line spectrum of hydrogen atom.
