B. Atomic radius of the element decreases as one moves across from left to right in the 2nd periodic table
C. Atomic isoelectronic species the smaller the positive charge on the cation , the smaller is the ionic radius
D. Amongst isoelectronic species, the greater the negative charge on the anion, the larger is the ionic radius.

Answer

c

Explanation

Among the isoelectronic species , the smaller is +ve charge, the large is the Ionic radius.
ionic radius : `Na^(+) gt Mg^(2+) gt AI^(3+)`
