Fluorine has the smallest radius of the halogens.
A dick that equals to 65 protons and 3 neutrons: c=3
Fluorine, because it has only two energy levels. All the rest have 3 to 7 energy levels, which increases their atomic radii.
Hydrogen with a covalent radius of 25 pm.
Flourine
fluorine
Chlorine will have the smallest atomic radius, bromine the largest.
The ionic radius of the iodide ion, I- is 206pm. It is one of the largest monatomic anions. The ionic radii of the halogen ions increase down the halogen group.
Helium, the noble gas with the smallest atoms.
It is krypton as it the far most right on the periodic table, having the smallest radius
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
Br is the atom with the smallest. K+ is the ion with the smallest radius. In general, the shape with the smallest radius has the smallest diameter
Helium has the smallest covalent radius
Hydrogen has the smallest atomic radius - 25 pm.
Chlorine will have the smallest atomic radius, bromine the largest.
The ionic radius of the iodide ion, I- is 206pm. It is one of the largest monatomic anions. The ionic radii of the halogen ions increase down the halogen group.
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
It is called the radius
The Hydrogen Ion has the smallest ionic radius.
It is krypton as it the far most right on the periodic table, having the smallest radius
Helium, the noble gas with the smallest atoms.
