Which of the following statements is correct about the size of atoms?
The size of atoms is in the range of nanometres.
Atoms are the basic units of matter. Their radii typically range from about 0.05 nm (hydrogen) to about 0.27 nm (caesium), which is within the nanometre (< 1 nm) to sub-nanometre range.
Atoms are NOT larger than molecules — molecules are made of two or more bonded atoms. Not all atoms are the same size; size increases down a group and decreases across a period. Atoms are far too small to be seen under an ordinary light microscope, which can resolve only about 200 nm.
The correct statement is : The size of atoms is in the range of nanometres.
