I am not aware of it "not being explained". I would guess that you can explain the relevant aspects with quantum mechanics.
The modern atom is explained by quantum mechanics.
She was attentive, as I explained the theory of quantum mechanics.
Quantum mechanics and relativity are both parts of the same puzzle: how the universe works. They are both equally important, because they both explain things that are not explained by classical physics.
I think the radio waves penetrate according to the barrier leakage or tunneling as explained by quantum mechanics.
all the way down to the smallest and then some
They're called atomic orbitals, and are explained through the use of quantum mechanics.
Principles of Quantum Mechanics was created in 1930.
The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics). Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non-relativistic quantum mechanics is still used, because it is a good approximation at low energies and it is much simpler. Physics students typically study regular quantum mechanics before moving on to quantum field theory.

Basically, quantum mechanics provides the answer for some questions which are previously unanswered like why the energies of each emited electron increases (but the number of electrons not increased) when the frequency of light waves striking the metal surface increased in photoelectric effect? This can only be explained when we regard light waves as particles (photons). So, it is the birth of particle-wave duality concept and quantum mechanics.
The concepts of quantum mechanics were not explored until the 20th century. Newton only lived into the 18th century, so Newton did no work on quantum mechanics.
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
