Why electron does not emit electromagnetic waves?
In quantum mechanics electron is considered as wave. Electrons actually act as a stationary wave, so there is no transfer of energy. So that is why they do not produce electromagnetic radiation.
Why don t the electrons fall into the nucleus then?
Quantum mechanics states that among all the possible energy levels an electron can sit in the presence of a nucleus, there is one, which has THE MINIMAL energy. This energy level is called the ground state. So, even if atoms are in a very very called environment, QM prohibits electrons from falling to the nucleus.
Why do electrons move?
When a negative charge is brought near one end of a conductor electrons are repelled. When electric voltage is applied, an electric field within the metal triggers the movement of the electrons, making them shift from one end to another end of the conductor. Electrons will move toward the positive side.
What happens to an electron when it emits electromagnetic radiation?
An electron can be excited when its absorbs energy from electromagnetic radiation. An excited electron can fall to a lower energy level. When this happens, energy is lost as electromagnetic radiation. Different changes in energy level cause the emission of different frequencies.
Do electrons really orbit the nucleus?
The electrons do not orbit the nucleus in the manner of a planet orbiting the sun, but instead exist as standing waves. Thus the lowest possible energy an electron can take is similar to the fundamental frequency of a wave on a string.
Why do electrons move around the nucleus?
They move because electron have a lot of energy. Electron is rotate around the nucleus because nucleus have a heavy part and positive charge of the atom so nucleus is stationary and then electron is light part and negative charge with respect to nucleus and not more energy so electron move around the nucleus.
Why do electrons move and not protons?
Electrons move freely within the structure of an atom but protons are bound in the nucleus and therefore immobile. Conductivity will therefore occur when electrons move from one atom to another and not protons due to their immobility.
Why do only electrons move and not protons?
Explanation: Electrons are located in shells surrounding the nucleus of the atom,whereas protons are present inside the nucleus. Electrons can move out of the shells on providing energy, but movement of proton will require a very high amount of energy (so as to break the nuclear force).
