Question

which unit is used to measure diameter of an atom​

Answer 1

Answer:

Atomic radii are measured in terms of angstrom (Å ). Anothet unit used for this purpose is nanometer which is equal to 1.0 × 10^- 9 m.

Answer 2

The size of the diameter of the atom is measured in the femtometer.

1 fermi =10⁻¹⁵ m

An isolated atom size can't be measured because we can't find the location of the electrons that surround the nucleus.

The size of the atom can be measured in a various way like:

1.covalent radius

2. ionic radius

3.van der Waal radius

4. metallic radius
