I dont know how on the atomic model... but i know that Thales Milutus began the theory. As the greek philosipher Democritus followed up on the idea.
With the protons
Protons and Neutrons and on the outside they are Electrons.
In the Bohr model of the atom, the number of protons is equal to the number of electrons because the atom is electrically neutral. The number of neutrons can be determined by subtracting the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number).
The nucleus contains protons and neutrons and is orbited by electrons. ( Apex 2021)
The proton has a positive charge, +1.
The atomic model includes protons, electrons and neutrons.

In a boron model, the neutrons would be located in the nucleus, along with the protons. Boron typically has 5 protons and an average of 6 neutrons, giving it an atomic mass of around 11.
The orange spheres represent protons, which have a positive charge, and the yellow spheres represent neutrons, which have no charge. Protons and neutrons make up the majority of the mass of an atomic nucleus.

A dense nucleus of protons and neutrons surrounded by electron clouds of different shapes and sizes.
electrons are in a cloud outside the nucleus
In John Dalton's model, the subatomic particles are electrons, protons, and neutrons. Electrons are negatively charged particles found in the electron cloud surrounding the nucleus. Protons are positively charged particles located in the nucleus. Neutrons are neutral particles also found in the nucleus.
Ah, the atomic model developed by James Chadwick is called the "neutron model." Just like adding a happy little tree to a painting, Chadwick added the neutron to the nucleus of an atom, bringing balance and stability to the structure. It's a beautiful addition to our understanding of the tiny world of atoms.
The proton has a positive charge, +1.
