Because the outermost layer of the shells of the noble gases is filled with the maximum number of electrons - 2 electrons into the s block (s orbital) and 6 electrons into the p block (per 2 in py, px, and pz orbitals).
A molecule is defined as a group of two or more atoms that are chemically bonded together, representing the smallest fundamental unit of a chemical compound. These atoms can be of the same element, forming diatomic molecules like O₂, or of different elements, forming compounds like H₂O. Molecules can vary in size and complexity, from simple diatomic molecules to large macromolecules such as proteins and DNA. The specific arrangement and types of atoms within a molecule determine its chemical properties and behavior.
Carbon is best able to combine with itself and hydrogen to form large molecules due to its ability to form strong covalent bonds with other carbon atoms and hydrogen. This allows for the formation of diverse carbon-based structures such as hydrocarbons, polymers, and complex biomolecules.
A molecule is formed when two or more atoms are joined together chemically, which can include atoms of the same element, like oxygen (O₂), or different elements, such as water (H₂O). The chemical bonds connecting the atoms can be covalent or ionic, depending on how the atoms share or transfer electrons. Molecules can vary in size and complexity, ranging from simple diatomic molecules to large macromolecules.
Potassium fluoride (KF) is not a diatomic molecule because it consists of an ionic bond between potassium (K) and fluoride (F) ions. In an ionic bond, the atoms do not share electrons to form covalent bonds, as is the case in diatomic molecules like O2 or N2.
No, oxygen is not a macromolecule. Macromolecules are large molecules made up of smaller subunits, like proteins, nucleic acids, carbohydrates, and lipids. Oxygen is a diatomic molecule, meaning it consists of two oxygen atoms bonded together.
Carbon is an element which does not tend to form diatomic molecules; it has a variety of different forms such as graphite, coal, or diamond, but all of these are characterized by very large aggregations, not diatomic molecules.
Astatine is not a diatomic element because it is in a group of halogens that are typically diatomic in nature, but astatine atoms are too large and unstable to form stable diatomic molecules. Its reactivity and nuclear instability make it difficult to exist as a diatomic molecule.

Yes, it is possible.
Many molecules such as organic molecules have significantly large amounts of atoms such as sugar/sucrose (C12H22O11). Others have more Many molecules such as organic molecules have significantly large amounts of atoms such as sugar/sucrose (C12H22O11). There other molecules such as DNA and polymers that have no size limit and there is no maximum size of a molecule.
Atoms are the same. In fact mostly light but molecules are very very large. So large that you cant write most of their symbol on the page
Propane consists of small molecules. It is a simple hydrocarbon compound that is composed of three carbon atoms and eight hydrogen atoms.

"polymerization"
A molecule containing a very large number of atoms.
