I don't understand what this is trying to say... can I have help?

The Bohr model was a one-dimensional model that used one quantum number to describe the distribution of electrons in the atom. Schrodinger's model allowed the electron to occupy three-dimensional space, and therefore required three quantum numbers, to describe the distribution of electrons in the atom.

Hi !

Since the atom is made of protons, electrons and neutrons, it is useful to determine how it is formed. It is known that the protons and neutrons are situated in the center of the atom.

However, it is not the case for the electrons. For high school purposes, you don't need to know what is a quantum number. You only need to know that the models were improved over time. Schrödinger gave a more just and complexe model since it calculates the position / distribution (in probability) of the electrons in the atom.

If you have any other questions, feel free to ask them !
