Electrons are present in stationary states. the electrons moves to higher energy level if it absorbs energy in the form of electromagnetic energy or moves to a lower energy state by emitting energy in the form of electromagnetic energy of appropriate frequency.

please thank me i request u

Hey there!

Answer:


With Thompson's model of atom, the \alpha particles would be expected to be only deflected by collisions with the electrons in the atom. On the basis of the result of alpha scattering experiment, Rutherford suggested the atom model:


1). An atom may be regarded as a sphere of diameter 10^{10} m but whole of the positive charge and almost the entire mass of the atom is concentrated in a small central core, called nucleus, having a diameter of 10^{-14} m.


2). The nucleus is surrounded by the electrons.
In other words, the electrons are spread over the remaining part of the atom, leaves the plenty of empty space in the atom.


3). As the atom is electrically neutral, the total positive charge on the nucleus is equal to the total negative charge of the electrons in the atom.


4). Rutherford pointed out that the electrons inside the atom are not stationary for if they were at rest, they would be pulled into the positive nucleus due to strong electrostaic force of attraction between the nucleus and the electrons.


He assumed that the electrons are resolving around the nucleus in circular orbits. The necessary centripetal force is provided to them by the electrostaic force of attraction between the nucleus and the electrons.
