215 pico meters. This is from my Inorganic Chemistry book.
Bismuth has an atomic radius of 156 picometers.
Ba has a larger atomic radius than Mg because Ba has more energy levels and electrons than Mg, leading to increased electron-electron repulsion which pushes the outer electrons further apart. This results in a larger atomic radius for Ba compared to Mg.
If you think to the atomic radius the empirical atomic radius of polonium is 168 pm.
The calculated atomic radius is 184 picometers.
Gallium has an atomic radius of 135 picometers.
the atomic radius of antimony is 159
Neodymium (Nd) has an atomic radius of 181 picometers.
The empirical atomic radius of carbon is 70 pm.
The other word for atomic radius includes the Van der Waals radius, ionic radius, and covalent radius. The atomic radius refers to half the distance between the nuclei of identical neighboring atoms in the solid form of an element.
The atomic radius of protactinium is 180 pm.
Gold has an atomic radius of 144 picometers.
Fluorine has the smallest atomic radius, while Francium has the largest atomic radius.
