The construction of atoms primarily involves the binding of protons and neutrons in the atomic nucleus, while electrons occupy the electron shells surrounding the nucleus. Strange and charm quarks, along with muons, belong to a different class of particles known as elementary particles. These particles do not directly participate in the formation of atoms as we commonly understand them.
However, in certain extreme conditions, such as those found in high-energy physics experiments or astrophysical environments, it is possible to observe exotic forms of matter that involve strange/charm quarks and muons. Let's consider two scenarios where such conditions could arise:
Quark-Gluon Plasma (QGP): At extremely high temperatures and densities, such as those achieved in particle accelerators or during the early stages of the universe shortly after the Big Bang, the strong nuclear force that binds protons and neutrons in atomic nuclei weakens. This leads to the formation of a state of matter known as the quark-gluon plasma, where quarks and gluons are deconfined and move freely. Under such conditions, strange and charm quarks can exist in a deconfined state along with up and down quarks. However, it's important to note that this state doesn't resemble the atomic structure we typically associate with atoms.
Neutron stars: Neutron stars are incredibly dense stellar remnants that form after a supernova explosion. The extreme pressures and densities in the core of a neutron star can give rise to unique conditions where strange/charm quarks and muons might exist. In the core of a neutron star, where matter is compressed to extreme densities, it is speculated that a form of matter called "strange matter" could exist. Strange matter consists of a sea of up, down, and strange quarks, forming a new kind of dense material. Muons can also exist in the core of a neutron star due to the extreme conditions. However, it's important to note that the precise nature of matter in neutron stars is still a topic of ongoing research and exploration.
In summary, while it is theoretically possible to encounter strange/charm quarks and muons in extreme environments like those mentioned above, the formation of atoms in the traditional sense involving these particles is not a naturally occurring phenomenon in the everyday conditions of the universe as we currently understand it.
