Mg
Chlorine will have the smallest atomic radius, bromine the largest.
Atomic radius (in 10^-12 m): K : 231 Ca: 197 Sc: 160 Ti: 146 (smallest)
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
atomic radius increases as you go down the group and decreases as you go across the period therefore the smallest atomic radius for group 14 is carbon.
It is krypton as it the far most right on the periodic table, having the smallest radius
Hydrogen has the smallest atomic radius - 25 pm.
Chlorine will have the smallest atomic radius, bromine the largest.
Argon doesnt have the smallest atomic radius, its chlorine.Argon has the largest atomic radius in period 3.
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

Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

Flourine and Phosphorous.
Fluorine has the smallest atomic radii because it is towards the right of the periodic table and on top.
atomic radius increases as you go down the group and decreases as you go across the period therefore the smallest atomic radius for group 14 is carbon.
It is krypton as it the far most right on the periodic table, having the smallest radius
