How many oxygen atoms lined up in a row would fit in a one nano meter space?

Seven is the correct answer to this question. To properly answer this question, we first need to identify a few things. First, we need to identify the atomic radius of the oxygen atom. This is approximately measured at .066nm. From there, we need to identify the oxygen atom's diameter.

To find the diameter, we would need to multiply .066 by two. This would give us .132nm. From there, we would divide the previous answer by 1. It gives us a fraction, but as atom numbers are not able to be expressed in fraction form, it would be 7 which is the integer value.

You will need to discover the covalent radius of oxygen in a single bonded state. The diameter of an oxygen atom, when lined up, is 0.146/1nm= 6.84. If you round that number up, it equals seven atoms. The covalent radius suggests the size of an atom that creates part of a single covalent bond.

Covalent radius is given in terms of picometers or angstroms. In theory, the sum of the two covalent radii should be equal to the length of the covalent bond length sandwiched between two atoms, but in practice, the bond's length depends on the chemical environment.

Different radii can be involved for single, double, or triple bonds in a dimensional sense. These relationships are not exact because the size of an atom is not stable. However, it all depends on its chemical environment.
