What is Quantum Tunneling?

Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in a minute!

In this episode we explain what quantum tunneling is and how it works!

For whom it might concern, how or why would there be an electron inside an atom? (Don't say, "because of quantum tunneling")

Is that speculative knowledge, current theory or science paradigm or perhaps even a factual observation?

The structure of an atom

Structure of an Atom by TutorVista

All matter is made up of atoms. An atom is like a tiny solar system. In the center of the atom is the nucleus which is a cluster of protons and neutrons. The protons have a positive electric charge while the neutrons are electrically neutral. The nucleus makes up almost all of an atom's mass or weight. Whirling at fantastic speeds around the nucleus are smaller and lighter particles called electrons which have a negative electric charge.

An atom has the same number of electrons (- ve charge) and protons (+ ve charge) to make the atom electrically neutral. An extremely powerful force, called the nuclear force, holds the protons together in the nucleus as they naturally repelled one another electrically.

The atoms of each chemical element have a different nucleus. An atom of hydrogen has one proton and no neutrons. An atom of nitrogen has 7 protons and 7 neutrons. Heavy elements have a large number of protons and neutrons. For example, the most common isotope of uranium, uranium-238 has 92 protons and 146 neutrons in its nucleus.

That isn't helpful in answering my question. Just let someone else try explain it.
