mg, ca,k ,rb magnesium, calcium, potassium, rubidium as you do down a group atomic radius increases as you go across a period atomic radius decreases
When going down the groups atomic radius increases. But going through rows radius decreases. Try to by heart the order as i did.
Atomic radius decreases from left to right across the periodic table, and increases as you go down the Periodic Table.
Covalent radii in picometres are: rubidium (235), potassium (220), calcium (180), magnesium (150), beryllium (105).
Be(Atomic Radius)- 94
Mg(Atomic Radius)-141
Ca(atomic radius)-176

Chlorine will have the smallest atomic radius, bromine the largest.
The atoms with the largest atomic radii are found in the lower right side of the periodic table. Smallest atoms are found in the higher left part of the periodic table. He has the smallest atomic radii.
Noble gases have the smallest atomic radius.
N, P, As and Sb

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.
Flourine and Phosphorous.
The atoms with the largest atomic radii are found in the lower right side of the periodic table. Smallest atoms are found in the higher left part of the periodic table. He has the smallest atomic radii.
Hydrogen has the smallest atomic radius - 25 pm.
Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
Noble gases have the smallest atomic radius.
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 increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl
