the electrons or more specifically the valence electrons
The electron was discovered by using cathode ray tubes. When it was discovered that the cathode ray diverted away from the negative end of a magnet to the positive end, it revealed that there was a negative particle present in the ray.
The Higgs boson is referred to as the God particle for the reason that this kind of particle is predicted in physics theory of the Standard Model. Although the particle has nothing to do with God, the belief is, that the detection of this particle would lead to many explanations about the creation of the universe and the big bang and what caused it.
Neils Bohr, in 1913.
Perhaps you meant the meson. Mesons are composed of two quarks, a quark and its antiquark. I'm not sure who predicted them but I believe the pi-meson was the first discovered. Then suddenly many more were discovered that were not predicted and they didn't know what to do until the current Standard Model was developed.
Strong force, weak force, and gravity
yes, they are depicted by a red subatomic particle.
The centre of an atom is called the nucleus. The nucleus contains protons, which have a positive charge and neutrons which have no charge. Electrons are also subatomic particles but they go around the nucleus so they are not in the centre.
Neutron. We didn't know about them yet. Chadwick discovered them some time later.

He added the proton. He thought that the only particle in the nucleus was the proton. The neutron was discovered much later by Chadwick.
a Bohr model is a diagram of an atom that describes the arrangement of the subatomic particles(electrons, neutrons, and protons) protons and neutrons are in the nucleus and the electrons in the electron shells.
Rutherford imagined the atom to be a particle with a thickly concentrated positive nucleus and electrons moving around it.
There are two main sections of an atom: the nucleus and the electron clouds. The nucleus is made up of two subatomic particles called protons and neutrons. The electron clouds are made up of, you guessed it, electrons, which are stored in different orbitals orbiting the nucleus in different directions. Each of the subatomic particles has different charges. Protons have positive charges, electrons have negative charges, and neutrons are neutral, so they have no charge.

Electron. It revolves the nucleus containing protons and neutrons and is the basic reason behind chemical reactions.According to the simplest Bohr model of the atom, the basic negatively charged particle is the electron.Electrons
Electron(s).
Both Democritus' and John Dalton's atomic models had no subatomic particles.
