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
