Answer :
Answer:
The size of an isolated atom can't be measured because we can't determine the location of the electrons that surround the nucleus. We can estimate the size of an atom, however, by assuming that the radius of an atom is half the distance between adjacent atoms in a solid. This technique is best suited to elements that are metals, which form solids composed of extended planes of atoms of that element. The results of these measurements are therefore often known as metallic radii.
.Explanation:
The radius of an atom is closest in size to a d. nanometer.
Atoms are very very small such that they cannot even be seen by normal microscopes. The size of an atom is about 10⁻¹⁰ meters so its radius is even smaller than that.
This means that it is closest in size to a nanometer which is about 10⁻⁹ meters.
The rest are simply too big because:
- a millimeter is only 10⁻³meters
- a micrometer is only 10⁻⁶ meters
- a minimeter is not a unit of measurement
In conclusion, the closest unit to that of the radius of an atom from the given options is a nanometer.
