Atomic radius is used to measure the size of an element and its mean distance from the center of the nucleus.

Explanation:

The following shows the atomic radius of the elements in ascending order

Option A:The atomic radius of Al,Na,S,Mg given as

Al=143, Na=186, S=104, Mg=160

The ascending order of above element based on their atomic radius value such as; S<Al<Mg<Na  

Option B:The atomic radius of C,Sn,Pb,Si given as

C=77, Sn=141, Pb=175, Si=117

The ascending order of these element based on their atomic radius value such as; C<Si<Sn<Pb

Option C:The atomic radius of K,Se,Ca,Br given as

K=227, Se=117, Ca=197, Br=114

The ascending order of these element based on their atomic radius value such as; Br<Se<Ca<K

Option D:The atomic radius of Be,Ca,C,B,Mg given as

Be=113, Ca=197, C=77, B=83, Mg=160

The ascending order of these element based on their atomic radius value such as; C<B<Be<Mg<Ca

Option E:The atomic radius of Ga,Al,Cl,P given as

Ga=122, Al=143, Cl=99, P=115

The ascending order of these element based on their atomic radius value such as; Cl<P<Ga<Al

Option F:The atomic radius of O,Se,S,Ne given as

O=73, Se=117, S=104, Ne=70

The ascending order of these element based on their atomic radius value such as; Ne<O<S<Se
