Nobody 'developed' quarks, they have always existed (well, ever since the Big Bang, anyway).
However, the current mathematical model we use to describe quarks was developed by Murray Gell-Mann and George Zweig in 1964.
String theory is the theory that smaller than atoms or even quarks are billions times smaller things called strings waving closed or open bands this is a big supporter of Universe or Multiverse?
4He Helium has two protons, two neutrons, and two electrons.
Atoms are composed of protons, electrons and neutrons (save hydrogen-1, which lacks any neutrons). Protons and neutrons are baryons, which are made up of three quarks. Having said that, the quark, which is a fundamental particle, is smaller than an atom by a great deal. Further, the quark is smaller than either a proton or neutron, as both are made of three quarks. The electron is a fundamental particle, and it is smaller still than a quark.When we look at the fundamental particles as they are described in the Standard Model, only the photon and gluon, which are force carriers, are smaller. It should be noted that the way we relate "smaller" in this case is by stating a mass-energy equivalence and describing the mass of the fundamental particles in terms of energy. Use the link below to see a chart of the sixteen particles that make up the three generations of matter.
A quark may be one of several categories: up (+2/3 charge), down (-1/3 charge), charmed, strange, top, and bottom. A quark, generally speaking, has no subparticles of its own that are generally accepted or discussed, but, in terms of size, the gluon, the gauge boson that mediates the "glue" force between the quarks can be construed as "smaller" in size than a quark.
There is no evidence of a smaller particle than the quarks and electrons and other fundamental particles, but there is a theory of smaller particles called "rishons". The theory states that there are T, V, t, and v rishons. The T and t rishons are antoparticles, the T's having an electric charge of +1/3, and the t's having -1/3. The v and V are antiparticles, but they are both neutral. (Again, this is only theory.)
Electrons for one, and protons and neutrons are composed of quarks
Atoms are considered the smallest unit of matter, made up of protons, neutrons, and electrons. Subatomic particles like quarks and leptons make up protons, neutrons, and electrons, but are not considered smaller than an atom.
A particle smaller than atom is a subatomic particle, protons , neutrons, and , electrons, the smallest one is an electron, smaller than that are point particles and elementary particles, one elementary particle and point particle is a quark, up quarks down quarks the smallest single thing found so far is a GLUON, which is the force which binds/holds quarks together. Where the devil lives in anti matter there are also atoms and subatomic particles and point particles but just anti, anti- GLUON, anti-QUARK, anti-ATOM, anti-SUBATOMIC PARTICLE. There is something called the string theory, and super string theory that theorizes about bosonic/boson strings but it can not be provine yet, and I think a gluon is still alot smaller than a bosonic/boson string if they are true.

When something is smaller than an atom, it is referred to as a subatomic particle. Subatomic particles include protons, neutrons, and electrons, which are the building blocks of atoms. Additionally, there are even smaller particles, such as quarks and leptons, which make up protons and neutrons. These particles are fundamental to the field of particle physics.

A quark is the smallest known particle, which makes up protons and neutrons found in the nucleus of atoms. This means that quarks are smaller than protons, neutrons, atoms, and molecules.
There are quarks in the nucleus of an atom, but they are found there because quarks make up protons and neutrons which make up atomic nuclei. They (quarks) do not have "individual identities" in the nucleus of an atom, but are elementary particles that are the building blocks of composite particles called hadrons. Quarks are never found in isolation anywhere.
protons/neutrons are made of quarks which are smaller than electrons. electrons are smaller than protons and neutrons.

Oh, dude, smaller than an atom? That's like asking what's smaller than a grain of sand in a desert. We're talking about subatomic particles here, like electrons, quarks, and neutrinos. It's a whole microscopic universe down there, man. So yeah, smaller than an atom? We're diving deep into the quantum realm, my friend.
