Question

Does an aqueous solution of $Mg_{2}^{+}$ ions have a larger entropy before or after hydration of the ions?

Answer 1

The chemical bond which involves the transfer of “one or more” electrons from one ion to another called ionic bond.

These two ion have opposite charges.

Example:

$Na\quad +\quad Cl\quad \rightarrow \quad Na^{ + }\quad +\quad { Cl }^{ - }\quad \rightarrow \quad NaCl$

The following factors are influence the ionic bond.

· “Low ionization” energy of metal atom

· The ions which are involved in bonding must be a different.

· High electron gain enthalpy of a non-metal atom.

· High lattice energy of compound  

· The electronegativity difference of ions which are involve in ionic bond must be greater than 1.7
