Question

compare the radii of two species X Y .Give reason for your answers A) X has 12 proton and 12 electron B) Y has proton and 10 electron​

Answer 1

Answer:

The radius of the element X will be larger then that of the size/radius of the element Y .

Explanation:

For the element X there are 12 electrons and 12 protons . Therefore , it is a neutral atom . Y has 12 protons and 10 electrons . So there are 2 more protons that gives Y a charge of +2 .

The atomic size of a cation is always smaller than a neutral atom . This is because cation has less number of electrons and hence more nuclear attractions on electron in cation . Thus the size of a cation is smaller than that of the neutral atom .
