In `AgBr` crystal , the ion size lies in the order `Ag^(+) lt lt Br^(-)` The `AgHt` crystal should have the following characheristics

In AgBr crystal , the ion size lies in the order Ag^(+) lt lt Br^(-) The AgBr crystal should have the following characheristics

The decreasing order of size of the following ions is

Which of the crystals should be the softest and have the lowest boiling point?

Assertion: The ionic radii follows the order: I^(-) lt I lt I^(+) . Reason: The smaller the value of Z//e the larger the size of the species.

Among the second period elements the actual ionisation enthalpies are in the order Li lt B lt Be lt C lt O lt N lt F lt Ne . Explain why? Be has higher (Delta_iH)_1 than B

Explain the order of electronegativity: I lt Br lt Cl lt F .
