Why don't electrons in the atom enter the nucleus?
Answers
Answer:
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.
Explanation:
Answer: Electrons are the negatively charged particles that surrounded the atom's nucleus. Electrons were discovered by scientist Sir J. J. Thomson in 1897.
In 1904, Scientist Sir Rutherford demonstrates the existence of positively charged nucleus that nearly all the mass of an atom.
In 1913, a student of Rutherford's created a new model for the atom; he proposed the electrons were arranged in concentric circles around the nucleus like patterned after the movement of planets around the sun i.e. Planetary Motion.
Along with this, he stated that electrons have fixed energy that allows them to avoid falling into nucleus analogous to the rungs of a ladder.
