Question

In the table below, there are sketches of four crystals made of positively charged cations and negatively-charged anions. Rank these crystals in decreasing order of stability (or equivalently increasing order of energy). That is, select "1" below the most stable (lowest energy) crystal. Select "2" below the next most stable (next lowest energy) crystal, and so forth OOOOO OOOOOO 0000001 OOOOOO 000000 (Choose one) හබයයයයි DO000 DO0000€ - DOO@OG D000006 DOO000 കൾക് (Choose one) OO000 00000 00000 DOOOOO DOOOOO DOO DOO OG DO+OA LAO

Answer 1

Solution:

The stabilty of a crystal is inversely proportional to its energy.

The stability depends upon the strength of lattice energy. Higher the lattice energy, higher will be the stability. The lattice energy increases with increasing charge and decreasing size of ions.

Therefore,

B > D > C > A
