Greater absolute charge - This is because ionic bond results from stronger electrostatic forces of attraction. - The higher the value of charges q₁ and q₂ the stronger will be the ionic bond.
The strength of an ionic bond depends on the ionic radius and the charges of the ions. With an increase in radius, there would be increase in the number if protons and this will also make the inner shells to be more complete. The smaller the radius the stronger the bond. In addition, the higher the number of electron lost, the more stronger the ionic bond.
The water molecules gets trapped in the crystal structure to be analysed and will give a peak in the spectra at about 3500 /cm , and there by hindering with the IR spectra of the sample to be analysed .
The second problem with the contamination of the sample with water is , that water makes the potassium bromide disc opaque which will decrease the absorption of the IR by the sample .
The answer is Strontium(Sr). The reactive increase from right to left. And this element has two valence electrons. So Rb is not correct. Then the very reactive metal is Sr.
The change of state that has been given in the question is called sublimation. It is actually the process in which a solid gets directly converted to gas without changing into liquid. I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
