Neil Bohr discovered that each electron shell has specified energy levels and limited place for electrons.
The atomic model has been refined from "the plum pudding" model,to a nucleus with orbiting electrons,to an awareness of many different sub atomic particles in the nucleus and electrons that are in energy levels,to electrons in sub energy levels and in distinct orbitals with different associated energy and behaviour
No, the tendency is to fill out lower energy levels first.
They have many names. Common ones are orbitals or energy levels.
The concept of quantized energy levels, first proposed by Neils Bohr, states that electrons can only exist in certain possible energy levels, which he pictured as orbits around a nucleus since the energy of an electron is proportional to its distance from the nucleus.

That was Niels Bohr
it was by a scientist called Bohr

The question is more than a little vague. The ground state electronic structure for boron is 1s2 2s2 2p1. In the absence of a magnetic field, this represents three distinct energy levels. The ground state electronic structure for carbon is 1s2 2s2 2p2, which also represents three distinct energy levels in the absense of a magnetic field. If a magnetic field is introduced, it complicates things, because depending on the exact strength of the field it's possible that boron could have electrons in as many as 5 distinct energy levels (and carbon could potentially have six), one for each of the electrons.

The scientist learn about carbon levels that in the atomosphere about carbon dioxide.
Nils Bohr designed an atomic model but eventually someone came up with an even more accurate model. He achieved the Nobel prize for physics.

Energy levels or Energy
Niels Bohr proposed the existence of seven distinct energy levels or electron orbits. He received the Nobel Prize in Physics in 1922.
