One millionth of a millimeter
Yes. One carbon atom is bonded to one oxygen atom by two covalent bonds and one coordinate covalent/dative bond, to form a complete molecule.
An atom bonded to only one atom
The size of a single atom can vary depending on the element, but typically it is on the order of 0.1 to 0.5 nanometers in diameter. This is incredibly small, with millions of atoms fitting across the width of a human hair.
I think you need to rephrase your question. The correct (if unhepful) answer is that one carbon atom comprises one atom. Did you mean to ask about protons, neutrons or electrons?
a regular atom
The atomic radius of silicon is approx. 0,11 nm.
About 1 Angstrom.

The width of a silicon atom is about 0.117 nanometers. In comparison to other atoms, silicon atoms are larger than hydrogen and helium atoms, but smaller than atoms like carbon and oxygen.
You would need to line up about 2,500,000 aluminum atoms to match the width of a human hair. This is because the width of a human hair is typically around 70 micrometers, and an aluminum atom is about 0.28 nanometers in diameter.
accuracy width can be changed but fixed width is a permanent one.
One atom of sodium and one atom of fluorine.
one car width
There is one atom in Hydrogen and one atom in Chlorine. All elements are composed of only one atom.
