why the electron does not stick to the nuclei?
Electrons do not stick to nuclei because they are constantly in motion and have a negative charge, which creates a repulsive force between the negatively charged electrons and the positively charged nucleus.
Electrons stay in orbit around the nucleus due to the balance between their kinetic energy and the attractive force of the positively charged nucleus. This balance is maintained by the quantum mechanical properties of electrons.
No, electrons cannot come into direct contact with the nucleus because of the Heisenberg uncertainty principle, which states that it is impossible to know both the position and momentum of an electron at the same time. This means that the electron's position is always uncertain and it can never be exactly at the same point as the nucleus.
If an electron gets too close to the nucleus, the repulsive force between the negatively charged electron and the positively charged nucleus will become stronger than the attractive force. This will cause the electron to be pushed away from the nucleus and back into its stable orbit.
Electrons have different energy levels in an atom because they can only exist in specific energy states, as dictated by the laws of quantum mechanics. The closer an electron is to the nucleus, the lower its energy level is. Electrons can move between energy levels by absorbing or emitting energy in the form of photons.
