Question

what is the radius of atom and nucleus

Answer 1

hey mate ⭐⭐⭐⭐⭐⭐

the radius of an atom is more than 10,000 times the radius of its nucleus (1–10 fm), and less than 1/1000 of the wavelength of visible light (400–700 nm).

Radius of a nucleus is of order 10−1510−15and generally measured in fermi or femtometer.

1Fermi=10−15meter1Fermi=10−15meter

1Fermi=1Femtometer1Fermi=1Femtometer

Radius of a nucleus increases with increase in number of nucleons. Nuclear radius ranges from1.75fm(1.75∗10−15)1.75fm(1.75∗10−15) for Hydrogen to 15 fm(15∗10−15)fm(15∗10−15) for heavy atoms as Uranium.

I hope it will help you..

$\huge\boxed{\fcolorbox{violet}{violet}{Answer}}$

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. ... Electrons do not have definite orbits, or sharply defined ranges.
