Question

Which is the correct units for measuring nuclear radii?
(1) Micron (2) Millimetre
(3)Angstorm (4) Fermi​

Answer 1

Answer:

the correct units for measuring nuclear radii is Fermi

Answer 2

Option 4 is correct

Fermi​

The femtometre (American spelling femtometer) sign fm (derived from the Danish and Norwegian term femten 'fifteen,' Ancient Greek: o, romanized: metron, lit. 'unit of measuring') is a SI unit of length equal to 1015 meters, or one quadrillionth of a meter . This distance was previously known as a fermi, and it was named after Italian-American physicist Enrico Fermi. It is a standard length-scale in nuclear physics.

1 femtometre = 1 fermi = 0.000001 nanometre = 1015 metres = 1000000 zeptometres

1 mm equals 1000000000000 femtometers.
