Which of the following compounds would be expected to have the strongest ionic bonds?
1)the compound that has the largest ions with the greatest charge
2)the compound that has the largest ions with the least charge
3)the compound that has the smallest ions with the greatest charge
4)the compound that has the smallest ions with the least charge

Answer;

3) the compound that has the smallest ions with the greatest charge

Explanation;

-Because metallic elements tend to lose electrons and nonmetallic elements tend to gain electrons, a pair of contrasting elements will exchange electrons so that both achieve stable electronic configurations. The resulting ions of opposite charge have a strong force of electrostatic attraction, which is called an ionic bond. This bond forms through the complete transfer of electrons from one atom to another, in contrast to the electron sharing of the covalent bond.

-The charge on the ions and the size of the ions involved determine the strength of ionic bonds. Generally the higher the charge on the ions the greater the attraction between the ions and therefore the greater the strength of the bond. The increased attraction between the ions leads to higher melting and boiling points.

the backbone of the dna and rna compound is sugar phosphate.
