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 cloud of electrons. Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius.
What is the diameter of a hydrogen atom? Answer Wiki. You can look up the covalent radius of hydrogen (37 pm), and double it for the diameter. where [math]\hbar = \frac{h}{2\pi}[/math], [math]k_e[/math] is the Coulomb constant, e is the charge on the electron and [math]m_e[/math] is the electron mass. This expression evaluates to 53 pm, so from this the diameter of a hydrogen atom would be 106 pm.
