Question

1-account for the following.(a)ionic radius of fluroide ion (F-)is 136 pm,while the atomic radius of fluroide (F)is only 64 pm.(b)the second ionization enthalpy of an element is always greater than that if the first ionization enthalpy.​

Answer 1

Answer:

This the ionic radius of fluoride ion (F–) is 136 pm whereas atomic radius of Fluorine (F) is only 64 pm. Loss of an electron from an atom results in the formation of a cation. A cation is smaller than its parent atom because it has fomer electrons while its nuclear charge remains the same
