a pair of spectacles
Phosphorus has larger ionic radius than sulfur. There is more nuclear attraction in sulfur.
Platinum; it has two more electron shells than nickel.
Potassium has a larger ionic radius than sulfur.
Barium has a larger atomic radius than tin.
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
more than one radius
If a mineral contains more than one element it is called a
Sodium (Na) has a larger atomic radius than aluminum (Al).

mixture
Atomic radius of Si is 111pm.Atomic radius of Pb is 175pm.Therefore lead has a larger atomic radius than silicon.
Element b would have a larger atomic radius than element c as you move down a group on the periodic table, the atomic radius tends to increase. This is because each successive element has an additional electron shell, leading to an increase in size.
